What are the constants in the equation 3x+2=9
a - 3
b - x
c - 2 and 9, constants have a fixed value
d - none of the above

Answers

Answer:

Option C i.e. 2 and 9, constants have a fixed value is a correct option.

Step-by-step explanation:

In algebra, a constant is basically a fixed value.

Sometimes, a constant is a number for a letter such as a, b, or c for a fixed number.

For example: in ''2x+7=3'', 7 and 3 are constants.

Please note that the number with variable x in the term is a coefficient.

In our case:

Given the equation

$3x+2=9$

Therefore, 2 and 9 are constants, having a fixed value.

Thus, option C i.e. 2 and 9, constants have a fixed value is a correct option.

find the quotient and remainder when 6x^4+ 11x^3+13x^2 -3x+27 is divided by 3x+4. also check the remainder obtained by using the remainder theorem.

Answers

The division of 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 will have a quotient of 2x³ + x² +3x -5 and a remainder of 47 using the remainder theorem.

What is the remainder theorem

The remainder theorem states that if a polynomial say f(x) is divided by x - a, then the remainder is f(a).

We shall divide the 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 as follows;

x⁴ divided by 3x equals 2x³

3x + 4 multiplied by 2x³ equals 6x⁴ + 8x³

subtract 6x⁴ + 8x³ from 6x⁴ + 11x³ + 13x² - 3x + 27 will give us 3x³ + 13x² - 3x + 27

3x³ divided by 3x equals x²

3x + 4 multiplied by x² equals 3x³ + 4x²

subtract 3x³ + 4x² from 3x³ + 13x² - 3x + 27 will give us 9x² - 3x + 27

9x² divided by 3x equals 3x

3x + 4 multiplied by 3x equals 9x² + 12x

subtract 9x² + 12x from 9x² - 3x + 27 will give us -15x + 27

-15x divided by 3x equals -5

3x + 4 multiplied by -5 equals -15x - 20

subtract -15x - 20 from -15x + 27 will result to a remainder of 47

using the remainder theorem, x = -4/3 from the the divisor 3x + 4

thus:

f(-4/3) = 6(-4/3)⁴ + 11(-4/3)³ + 13(-4/3)² - 3(-4/3) + 27 {putting the value -4/3 for x}

f(-4/3) = (1536/81) - (704/27) + (208/9) + (12/3) + 27

f(-4/3) = (1536 - 2112 + 1872 + 324 + 2157)/81 {simplification by taking the LCM of the denominators}

f(-4/3) = (5919 - 2112)/81

f(-4/3) = 3807/81

f(-4/3) = 47

Therefore, the quotient of after the division of 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 is 2x³ + x² +3x -5 and there is the remainder of 47 using the remainder theorem.

A company is re-evaluating the way they produce standard staple strips. Staples are individually cut from one piece of wire then bent and bonded to other staples before being put into boxes for distribution. The company currently uses 8-meter pieces of wire to create these staple strips; however, four other lengths are also available for use. Which is the shortest available wire that can be used to make a staple strip? A. 4-meter piece B. 5-meter piece C. 6-meter piece D. 7-meter piece

Answers

Answer:

Step-by-step explanation:

The given parameters are;

The length currently used to make staple strips by the company = 8-meter pieces

The process of making staples by the company = Cut, bending, and bonding

Therefore, given that the process of manufacturing staple strips are by cutting strips of wire, we have;

The wire most suitable for the manufacture of staple strips is a wire that is a factor of 8

Therefore, among the given options, the wire with length l = 4-meters which is the 8-meter length split into two, is the most suitable, because 4-meter = 8-meter/2, whereby 4 is seen as a factor 8 or 8 = 4 × 2, such that two 4-meter wire strips will make the same quantity of staple pins as one 8-meter strip.

Which values of x are solutions to the equation below 15x^2 - 56 = 88 - 6x^2?
a. x = -4, x = 4
b. x = -4, x = -8
c. x = 4, x = 8
d. x = -8, x = 8

Answers

A quadratic equation is a polynomial equation of degree 2, which means the highest power of the variable is 2. It is generally written in the form: ax^2 + bx + c = 0. Option (d) x = -8, x = 8 is the correct answer.

The given equation is 15x^2 - 56 = 88 - 6x^2.

We need to find the values of x that are solutions to the given equation.

Solution: We are given an equation 15x² - 56 = 88 - 6x².

Rearrange the equation to form a quadratic equation in standard form as follows: 15x² + 6x² = 88 + 56 21x² = 144

x² = 144/21 = 48/7

Therefore x = ±sqrt(48/7) = ±(4/7)*sqrt(21).

The values of x that are solutions to the given equation are x = -4/7 sqrt(21) and x = 4/7 sqrt(21).

The given equation is 15x² - 56 = 88 - 6x². Values of x are solutions to the equation below 15x² - 56 = 88 - 6x² are x = -2.62, 2.62 or x ≈ -2.62, 2.62.

Firstly, let's add 6x² to both sides of the equation as shown below.

15x² - 56 + 6x² = 88

15x² + 6x² - 56 = 88

Simplify as shown below.

21x² = 88 + 56

21x² = 144

Now let's divide both sides by 21 as shown below.

x² = 144/21

x² = 6.86

Now we need to solve for x.

To solve for x we need to take the square root of both sides.

Therefore, x = ±√(6.86).

Therefore, the values of x are solutions to the equation below are x = -2.62, 2.62 or x ≈ -2.62, 2.62.

-4)) is
1. (-4,-41)
2. (-6,1)
3. (-1,6)
4. (1,-6)

Answers

To find T((5, -4)), we can use the linearity property of linear transformations. First, we can express (5, -4) as a linear combination of the given basis vectors:(5, -4) = 5*(1, 2) + (-6)*(0, 1)

Since T is a linear transformation, we can apply it to each term separately:

T((5, -4)) = T(5*(1, 2) + (-6)*(0, 1))

Using the linearity property of T, we have:

T((5, -4)) = 5*T((1, 2)) + (-6)*T((0, 1))

From the given information, we know that T((1, 2)) = (2, 3) and T((0, 1)) = (1, 4). Substituting these values, we get:

T((5, -4)) = 5*(2, 3) + (-6)*(1, 4)

= (10, 15) + (-6, -24)

= (10 + (-6), 15 + (-24))

= (4, -9)

Therefore, T((5, -4)) is (4, -9). None of the options provided match this result, so the correct answer is not among the given choices.

Answers

The argument is weak and uncogent. The argument is weak because it relies on an assumption without sufficient evidence or reasoning. It is also uncogent because it lacks the necessary support to make the conclusion reliable.

The argument states that the range of C scores on the exam is 70–79, and since the person got a C on the exam, they assume they got a 75. This is a weak argument because it relies solely on the assumption that the person's C grade falls exactly in the middle of the given range.

The argument is uncogent because it fails to provide sufficient evidence or logical reasoning to support the conclusion. It assumes that the person's C grade must be exactly in the middle of the range without considering other possibilities or factors that may affect the grading system.

The argument overlooks important factors such as the specific grading criteria, individual performance relative to other students, potential grade curves, or any specific feedback provided by the instructor. Without this additional information, it is not reasonable to conclude that the person's grade is exactly 75.

To make the argument stronger and cogent, additional evidence or reasoning should be provided, such as specific grading criteria or feedback from the instructor, to support the conclusion that the person's grade is most likely a 75 within the given C range.

Step-by-step explanation:

When you take a number to the power of a fraction, you write it as the root of the denominator to the power of the numerator. The denominator is the bottom number and the numerator is the top number.

Given the slope and a point on the line, find the equation of the line in
the form y = mx + b. Identify the y-intercept.

m=7/4

(4,-6)

Answers

The equation of line in slope intercept form is y=(7/4)x-13 and the y-intercept is b=-13.

Given that a line is passes through the point (4,-6) and the slope is m=7/4.

We want a line that passes through (4,-6) and the slope is m=7/4.

To find the equation of a line we want to write the equation in the form y=mx+b where m is the slope and b is the y-intercept.

Given that the m=7/4.

The given point is (x₁,y₁)=(4,-6).

Now, we will write our equation by using the point-slope form. The point-slope form is:

y-y₁=m(x-x₁)

Now, we will substitute the values to find new equation, we get

y-(-6)=(7/4)(x-4)

y+6=(7/4)(x-4)

Further, we will apply the distributive property a(b+c)=ab+ac, we get

y+6=(7/4)x-(7/4)4

y+6=(7/4)x-7

Now, we will subtract 6 from both sides, we get

y+6-6=(7/4)x-7-6

y=(7/4)x-13

Hence, the equation of line in slope intercept form where a line that passes through (4,-6) and the slope m=7/4 is y=(7/4)x-13 and the y-intercept form is b=-13.

Applying DeMorgan's law to the given propositions, we have:

¬((w∨p)∧(¬q∧q∧w)) ≡ ¬(w∨p)∨¬(¬q∧q∧w).

By negating the conjunction and distributing the negations, the logical equivalence is maintained. Therefore, the correct choice is:

what is the solution to the equation sqrt x^2 2x-25 ? assume the range is all real numbers.

Answers

The solution to the equation $sqrt(x^2 + 2x - 25)$for all real numbers is: x ∈ [-5, 3]

We can begin by observing that the term within the square root is a quadratic polynomial, and we can rewrite it as follows:$x^2 + 2x - 25 = (x + 5)(x - 3)$.Now, let us consider the square root of this expression: $sqrt[(x + 5)(x - 3)].$ Since the range is all real numbers, this expression is only defined for values of x such that (x + 5)(x - 3) is non-negative or greater than or equal to zero. This means that either (x + 5) and (x - 3) are both positive, or both negative.

We can create an inequality to represent this condition:(x + 5)(x - 3) ≥ 0Now we can plot the two roots, -5 and 3, on a number line. These are the points where the function changes sign. Between these points, the inequality (x + 5)(x - 3) ≥ 0 will be satisfied if both factors are negative, or both factors are positive. We can also note that $(x + 5)(x - 3) = x^2 + 2x - 25$ is zero at the two roots, -5 and 3. This means that the inequality will be satisfied if x lies on the interval [-5, 3].

You have to create 3 functions to make hills on a grap

Requirements are in the photo.

4. Write equations for three hills that do meet the requirements. Sketch them on one axis. (For the
purposes of this exercise, this is a sketch, so the steepness and minimums and maximums of the
graphs do not need to be exact). (6 points: 1 point for each equation, 1 point for each sketched curve)

Answers

Answer:

Hill 1: F(x) = -(x + 4)(x + 3)(x + 1)(x - 1)(x - 3)(x - 4)

Hill 2: F(x) = -(x + 4)(x + 3)(x + 1)(x - 1)(x - 3)(x - 4)

Hill 3: F(x) = 4(x - 2)(x + 5)

Step-by-step explanation:

Hill 1

You must go up and down to make a peak, so your function must cross the x-axis six times. You need six zeros.

Also, the end behaviour must have F(x) ⟶ -∞ as x ⟶ -∞ and F(x) ⟶ -∞ as x⟶ ∞. You need a negative sign in front of the binomials.

One possibility is

F(x) = -(x + 4)(x + 3)(x + 1)(x - 1)(x - 3)(x - 4)

Hill 2

Multiplying the polynomial by -½ makes the slopes shallower. You must multiply by -2 to make them steeper. Of course, flipping the hills converts them into valleys.

Adding 3 to a function shifts it up three units. To shift it three units to the right, you must subtract 3 from each value of x.

The transformed function should be

F(x) = -2(x +1)(x)(x -2)(x -3)(x - 6)(x - 7)

Hill 3

To make a shallow parabola, you must divide it by a number. The factor should be ¼, not 4.

The zeroes of your picture run from -4 to +7.

One of the zeros of your parabola is +5 (2 less than 7).

Rather than put the other zero at ½, I would put it at (2 more than -4) to make the parabola cover the picture more evenly.

The function could be

F(x) = ¼(x - 2)(x + 5).

In the image below, Hill 1 is red, Hill 2 is blue, and Hill 3 is the shallow black parabola.
