Think carefully about the angle relationship the following represents.

What is the value of ∠JML?

Answer:

For the first equation, it is "True for one value of x."

For the second equation, it is "True for no value of x."

For the third equation, it is "True for all values of x."

Step-by-step explanation:

Just solve the equation and check the numbers:

If both numbers are the same, it is "true for all values of x"

If there is a variable and a number, it is "true for one value of x"

If there are two numbers and they are different, it is "true for no values of x"

We need to check whether the given equations are true for all values of \(x\) , one value of \(x\) , or no values of \(x\) .

The equations are ,

solve this equation for x ,

\(\longrightarrow 3x +9=-4.5x+20\\\)

\(\longrightarrow 3x+4.5x =20-9\\\)

\(\longrightarrow 7.5x =11\\\)

\(\longrightarrow \underline{\underline{x =\dfrac{11}{7.5}}}\)

Hence the equation is true for one value of x .

solve out for x ,

\(\longrightarrow 9x +27=9x-12\\ \)

\(\longrightarrow 9x -9x =-27-12\\ \)

\(\longrightarrow 0 = -39\)

This can never to true , so the equation is true for no values of x .

solve out for x ,

\(\longrightarrow 8x+12=12+8x \\\)

\(\longrightarrow 12-12=8x-8x\\\)

\(\longrightarrow 0=0 \)

Hence this equation is true for all values of x .

There are 10 students in a class, 6 of them wear glasses. If a student is chosen at random from the class, then the probability that they do not wear glass is 2/5

Total number of Students = 10

Students who wear glasses = 6

Students who don't wear glasses = 4

Probability is the ratio of favorable outcomes to the total favorable outcomes. The probability formula can be expressed as,

P(E) = (Number of favorable outcomes) ÷ (Total favorable outcomes).

The probability of a student not wearing glasses is,

Probability = Students who don't wear glasses/Total number of Students

Probability = 4/10 i.e., 2/5

Answer:

The equation in the point-slope form for the line that passes through point (-1, -4) and has a slope of -3 is y+4=-3(x+1).

Step-by-step explanation:

Given that:

Line passes through the point = (-1, -4)

Slope of the line = -3

Point slope form of a line is given by;

\(y-y_1=m(x-x_1)\)

Here,

x1 = -1 , y1 = -4 and m = -3

Putting the values in the point-slope form of the equation,

y-(-4) = -3(x-(-1))

y+4= -3(x+1)

Hence,

The equation in the point-slope form for the line that passes through point (-1, -4) and has a slope of -3 is y+4=-3(x+1).

The solution to the system of linear equation above is (7, 3).

To solve the following system of linear equations by elimination method:

3x - 4y = 19

-3x + 4y = 25

We can add the equations together to eliminate the variable y, resulting in 6x = 44.

We can solve for x by dividing both sides by 6, so x = 7.

We can substitute the value of x (7) into either of the original equations to solve for y. In this case, we can use 3x - 4y = 19 and substitute in x = 7. Therefore, 4y = 12 and y = 3.

The solution to the system is (7, 3).

Answer:

To solve the equation x^2 + 4x = 56, we can start by rearranging it to the standard quadratic form:

x^2 + 4x - 56 = 0

Next, we can use the quadratic formula to solve for x:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = 4, and c = -56, so we have:

x = (-4 ± sqrt(4^2 - 4(1)(-56))) / 2(1)

x = (-4 ± sqrt(240)) / 2

x = (-4 ± 15.49) / 2

x = (-4 + 15.49) / 2 or x = (-4 - 15.49) / 2

x = 5.745 or x = -9.745

Therefore, the solutions to the equation x^2 + 4x = 56 correct to one decimal place are x = 5.7 and x = -9.7

Here are the answer choices:

a) (-8,-1)

b) (0,-3)

c) (-2,-4)

d) (4,-4)

We are asked to choose the coordinate pair that is NOT a solution, so let's just test each option!

To test answer choice "a", plug in \(x=-8\) and \(y=-1\) into the original equation, then simplify:

Plug in values: \(-1=-\frac{1}{4} (-8)-3\)

Multiply: \(-1=2-3\)

Subtract: \(-1=-1\)

Notice that we now have a true expression, therefore option "a" IS A SOLUTION, and is thus not the correct answer.

Repeat for option "b" (0, -3):

Plug in values: \(-3=-\frac{1}{4}(0)-3\)

Multiply: \(-3=-3\)

Slope (m) of RH = 3/4

Distance of RH is d =5 units

Midpoint between points R and H is: M(1, 3.5)

Slope (m) = change in y / change in x = y2 - y1/x2 - x1, where:

R(3, 5) = (x1, y1)

H(-1,2) = (x2, y2)

Plug in the values

Slope (m) = (2 - 5) / (-1 - 3)

Slope (m) = (-3) / (-4)

Slope (m) of RH = 3/4

How to Find the Distance between two Points?

Distance formula used is: \(\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\)

R(3, 5) = (x1, y1)

H(-1,2) = (x2, y2)

Plug in the values

RH = √[(−1−3)² + (2−5)²]

RH = √[(−4)² + (−3)²]

RH = 5 units

How to Find the Midpoint?

The midpoint formula used is: M[(x2 + x1)/2, (y2 + y1)/2)

R(3, 5) = (x1, y1)

H(-1,2) = (x2, y2)

Substitute the values

M[(-1 + 3)/2, (2 + 5)/2)

M(1, 3.5)

Therefore,

Slope (m) of RH = 3/4

Distance of RH is d =5 units

Correct answer is " Find a polynomial of the statement For the month of January, the amount of snowfall was 3 inches above average"

To find this value, we need to perform matrix multiplication on matrices A and B. Matrix A is a 3x3 matrix and matrix B is a 3x4 matrix. The product of these two matrices will result in a 3x4 matrix. The exact value of the element in the 3rd row and 2nd column of the product AB is -18.96.

In the given problem, we are interested in the element located in the 3rd row and 2nd column of the resulting product matrix. To obtain this value, we need to multiply the elements of the 3rd row of matrix A with the corresponding elements of the 2nd column of matrix B, and then sum the products.

The calculation involves multiplying (-5) from matrix A with 2 from matrix B, (-4) from matrix A with 0 from matrix B, and (-3.2) from matrix A with 2.8 from matrix B. Then, we sum these products to find the value of the element in the 3rd row and 2nd column of the product AB.

To find the value of the element in the 3rd row and 2nd column of the product AB:

(-5)(2) + (-4)(0) + (-3.2)(2.8) = -10 + 0 + (-8.96) = -18.96

Therefore, the exact value of the element in the 3rd row and 2nd column of the product AB is -18.96.

Therefore, the maximum blood pressure of 200 mmHg occurs at approximately 0.524 seconds, and the minimum blood pressure of 120 mmHg occurs at approximately 1.571 seconds within the time interval 0 ≤ t ≤ 0.75.

To find the maximum and minimum values of the blood pressure function p(t), we need to examine the behavior of the sinusoidal term, -40sin(3t), within the given time interval. The function is a sine wave with an amplitude of 40 and a period of 2π/3. This means that the maximum value occurs at the peak of the sine wave (amplitude + offset), and the minimum value occurs at the trough (amplitude - offset).

The maximum blood pressure corresponds to the peak of the sine wave, which is 40 + 160 = 200 mmHg. To find the time at which this occurs, we set the argument of the sine function, 3t, equal to π/2 (since the peak of the sine wave is π/2 radians). Solving for t gives t = (π/2) / 3 = π/6 ≈ 0.524 seconds.

Similarly, the minimum blood pressure corresponds to the trough of the sine wave, which is -40 + 160 = 120 mmHg. Setting the argument of the sine function equal to 3π/2 (the trough of the sine wave), we find t = (3π/2) / 3 = π/2 ≈ 1.571 seconds.

Therefore, the maximum blood pressure of 200 mmHg occurs at approximately 0.524 seconds, and the minimum blood pressure of 120 mmHg occurs at approximately 1.571 seconds within the time interval 0 ≤ t ≤ 0.75.
