Question

Find the output of the function y equals -3x - 7 when input is -5

Answer 1

Find the value of the function y equals 3x to the second power minus 21 when x equals 4

Answer 2

When the input is x equals 0.3, which of the following is the output of the function y equals 3x + 6

a. 9
b. 0.3
c. 6.3
d. 6.9

Answer 3

are you sure

Answer 4

What is the value of the function y equals 1/8x minus 13 when x equals negative 4

Answer 5

To find the output of the function, we substitute the input value (-5) for x in the function y = -3x - 7 and solve for y.

y = -3(-5) - 7
y = 15 - 7
y = 8

Therefore, when the input is -5, the output of the function y = -3x - 7 is 8.

Answer 6

To find the value of the function, we substitute the input value (4) for x in the function y = 3x^2 - 21 and solve for y.

y = 3(4)^2 - 21
y = 3(16) - 21
y = 48 - 21
y = 27

Therefore, when x is equal to 4, the value of the function y = 3x^2 - 21 is 27.

Answer 7

To find the output of the function when the input is x = 0.3, we substitute the input value x = 0.3 in the function y = 3x + 6 and solve for y.

y = 3(0.3) + 6
y = 0.9 + 6
y = 6.9

Therefore, when x is equal to 0.3, the output of the function y = 3x + 6 is 6.9.

Therefore, the correct answer is d. 6.9.

Answer 8

I made an error in my previous response. Let me correct that calculation again.

Given:
y = 3x + 6
x = 0.3

Substitute x = 0.3 into the function:
y = 3(0.3) + 6
y = 0.9 + 6
y = 6.9

Therefore, when x is equal to 0.3, the output of the function y = 3x + 6 is 6.9

So, the correct answer is indeed d. 6.9.

Answer 9

To find the value of the function, we substitute the input value (-4) for x in the function y = (1/8)x - 13 and solve for y.

y = (1/8)(-4) - 13
y = (-1/2) - 13
y = -0.5 - 13
y = -13.5

Therefore, when x is equal to -4, the value of the function y = (1/8)x - 13 is -13.5.
