A polynomial is an expression consisting of variables and coefficients and factoring is the process of breaking down a polynomial into simpler units

A polynomial is an expression consisting of variables and coefficients, which are combined using only addition, subtraction, and multiplication. For example, 3x^2 + 2x - 1 is a polynomial, where x is the variable, 3 and 2 are coefficients, and ^2 and ^1 are exponents.

Factoring is the process of breaking down a polynomial into simpler units, which can be multiplied together to obtain the original polynomial. The simplest units are usually linear expressions, which have the form ax + b, where a and b are coefficients. For example, the polynomial 3x^2 + 2x - 1 can be factored into (3x - 1)(x + 1) by identifying two linear expressions that when multiplied together produce the original polynomial.

Factoring is an important tool in algebra, as it can help to simplify expressions, solve equations, and identify the roots of a polynomial.

The inequality to determine the number of runs per inning, p Kim's team could have scored is; 4r + 6 > 17

Let r represent the number of runs per inning. Thus for 4 innings, we have 4r.

The team already has 6 runs. Now add the additional runs to this to get;

4r + 6

The team wants to score more than the other team, this means they need more than 17 and so the inequality required is;

4r + 6 > 17

Subtract 6 from each side to get;

4r + 6 - 6 > 17 - 6

4r > 11

Divide both sides by 4 to get:

r > 2.75

Approximating to a whole number gives;

r > 3

Step-by-step explanation:

The amount of money that you will have in eight years from today is $29,315.79 (rounded to 2 decimal places).

To find out the amount of money that you will have in eight years, you need to use the future value formula, which is:FV = PV × (1 + r)n

Where, FV = future value

PV = present value (initial investment) r = annual interest rate (as a decimal) n = number of years

First, you need to find the future value of the gift amount of $17,000 in two years.

Since it's a gift and not an investment, we can assume an interest rate of 0%.

Therefore, the future value would simply be:

PV = $17,000r = 0%n = 2 years

FV = $17,000 × (1 + 0%)2FV = $17,000

Now, you will loan that amount at 9.75% interest for six more years.

So, you need to find the future value of $17,000 after 6 years at an annual interest rate of 9.75%.

PV = $17,000

r = 9.75%

n = 6 years

FV = $17,000 × (1 + 9.75%)6

FV = $29,315.79

Therefore, the amount of money that you will have in eight years from today is $29,315.79 (rounded to 2 decimal places).

The boundaries of the class 1.87-3.43 are D) 1.865-3.435. The lower boundary is 1.865 and the upper boundary is 3.435.

The boundaries of the class 1.87-3.43 can be determined by subtracting and adding half of the smallest possible unit of measurement to the given class limits. In this case, since the given class limits are 1.87 and 3.43, we need to find the boundaries by subtracting and adding half of the smallest possible unit of measurement.

Let's assume the smallest possible unit of measurement is 0.01.

To find the lower boundary:

Lower Boundary = Lower Limit - (0.01/2)

Lower Boundary = 1.87 - 0.005

Lower Boundary = 1.865

To find the upper boundary:

Upper Boundary = Upper Limit + (0.01/2)

Upper Boundary = 3.43 + 0.005

Upper Boundary = 3.435

Therefore, the boundaries of the class 1.87-3.43 are:

The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.

To solve the inequality y + 7 ≤ -1, we need to isolate the variable y on one side of the inequality sign.

Starting with the given inequality:

y + 7 ≤ -1

We can begin by subtracting 7 from both sides of the inequality:

y + 7 - 7 ≤ -1 - 7

y ≤ -8

The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.

In the context of a number line, all values to the left of -8, including -8 itself, will make the inequality true. For example, -10, -9, -8, -8.5, and any other value less than -8 will satisfy the inequality. However, any value greater than -8 will not satisfy the inequality.

Answer: $4

Step-by-step explanation:

Answer:

x = 11

z = 86

Step-by-step explanation:

8x + 6 and 10x-16 are vertical angles

Vertical angles are pairs of angles that are opposite each other and have the same vertex, or point of intersection. They are formed when two lines intersect at a point, and are always congruent, or of equal measure.

To solve this equation, we need to isolate the variable x on one side of the equation. To do this, we can start by subtracting 6 from both sides of the equation:

8x + 6 - 6 = 10x - 16 - 6

8x = 10x - 22

Now we can subtract 8x from both sides of the equation:

8x - 8x = 10x - 22 - 8x

0 = 2x - 22

To solve for x, we can add 22 to both sides of the equation:

0 + 22 = 2x - 22 + 22

22 = 2x

Finally, we can divide both sides of the equation by 2 to find the value of x: 22 / 2 = 2x / 2

x = 11

Therefore, the solution to the equation is x = 11.

Now that we have x, z is a supplementary angle to 8x + 6 (or you could do 10x - 16)

Supplementary angles are pairs of angles that add up to 180 degrees. They are formed when two lines intersect at a point, and the angles formed at the intersection are supplementary.

First plug in x, 8x + 6 = 8(11) + 6 = 88 + 6 = 94

180 - 94 = z

z = 86

Answer: 201

Step-by-step explanation: Ok this is very simple for those of you who are stuck on this. First you divide 12 by 268. You would get 22 with a remainder of 4. This in fractions would be 22 1/3. So he would be driving 22 1/3 miles with 1 galloon of gas. If you multiply this by 9 you would get 201 miles which is how much he can drive in 9 gallons of gas.

Answer:

\(y = \frac{1}{3} x - 2\)  (But I can't find it in your options)

Step-by-step explanation:

The coordinates are (0,-2) and (6,0)

Finding the slope:

=> Slope = \(\frac{rise}{run}\)

=> Slope = \(\frac{y2-y1}{x2-x1}\)

=> Slope = \(\frac{0+2}{6-0}\)

=> Slope = 2/6

=> Slope = m = 1/3

Finding the y-intercept:

y-intercept = b = -2

Because this is the point where x = 0 According to coordinate (0, -2)

So, the slope intercept equation becomes:

=> \(y = mx+b\)

=> \(y = \frac{1}{3} x - 2\)

Answer:

y = 1/3 x - 2.

Step-by-step explanation:

The slope of the line = (y2 - y1)/(x2 - x1)

= ( 0 - (-2)) / (6 - 0)

= 2/6

= 1/3.

Using the point slope form of the line  with m = 1/3 and (x1,y1) = (0,-2):

y - y1 = m(x - x1)

y - (-2) = 1/3(x - 0)

y + 2 = 1/3 x    

y = 1/3 x - 2.

The expected number of games before Paul goes broke is 7.5.

Let X be the number of games played before Paul goes broke. For each game, Peter wins with probability p = 2/3, and loses with probability 1-p = 1/3. Let Y be the amount of money won by Peter in each game. Then Y = 1 with probability p, and Y = -1 with probability 1-p. The expected value of Y is:

E(Y) = (1)(p) + (-1)(1-p) = 2p - 1 = 1/3

The expected value of X can be found using the formula:

E(X) = E(total amount won by Peter) / E(Y)

Since Peter starts with no money and Paul starts with $10, the total amount won by Peter after X games is 10 - X. Thus, we have:

E(X) = (10 - E(total amount won by Paul)) / E(Y)

The total amount won by Paul after X games is X dollars, since he bets one dollar on each game. Thus:

E(total amount won by Paul) = X

Substituting this into the previous formula, we get:

E(X) = (10 - X) / (1/3) = 30 - 3X

To find the expected value of X, we need to solve the equation E(X) = 30 - 3X for X. This gives:

4X = 30

X = 7.5

Therefore, the expected number of games before Paul goes broke is 7.5.

Step-by-step explanation:

The problem uses division, but we can create a proportion to see how the division works.

Since we know that Chelsea can make 1 hamburger with 0.16 pounds and allow x to represent the number of burgers Chelsea can make with 2.24 lbs of meat, we have:

\(\frac{2.24}{x}=\frac{0.16}{1}\)

\(2.24=0.16x\)

As the proportion shows, we can divide 2.24 by 0.16 to get x = 14.

Check: 0.16 lbs * 14 patties = 2.24 lbs

Answer:

1 1/2 cups

Step-by-step explanation:

original amount = 2 1/4 cups = (2 × 4 + 1)/4 cups = 9/4 cups

2/3 of original amount = 2/3 × 9/4 cups = 18/12 cups = 3/2 cups = 1 1/2 cups

The angle is 25 degrees

The inverse matrix of the given matrix using Gauss-Jordan elimination method is:

[-7, 4, 0 ]

[-1, 0.5, 0 ]

[-0.5, 0.25, 0.5 ]

To find the inverse matrix using Gauss-Jordan elimination, we augment the given matrix with an identity matrix of the same size:

[1, -2, 0 | 1, 0, 0]

[2, -6, 4 | 0, 1, 0]

[0, -1, 3 | 0, 0, 1]

Next, we perform row operations to transform the left side of the augmented matrix into an identity matrix. We start by performing row operations to create zeros below the diagonal entries:

[1, -2, 0 | 1, 0, 0]

[0, 2, 4 | -2, 1, 0]

[0, -1, 3 | 0, 0, 1]

Next, we use row operations to create zeros above the diagonal entries:

[1, 0, 8 | -7, 4, 0]

[0, 1, 2 | -1, 0.5, 0]

[0, 0, 2 | -1, 0.5, 1]

At this point, the left side of the augmented matrix has been transformed into an identity matrix, while the right side has become the inverse matrix:

[1, 0, 0 | -7, 4, 0]

[0, 1, 0 | -1, 0.5, 0]

[0, 0, 1 | -0.5, 0.25, 0.5]

Therefore, the inverse matrix of the given matrix is:

[-7, 4, 0 ]

[-1, 0.5, 0 ]

[-0.5, 0.25, 0.5 ]

By performing the necessary row operations using the Gauss-Jordan elimination method, we have successfully obtained the inverse matrix. The inverse matrix is a useful tool in various mathematical operations, such as solving linear equations and computing transformations.
