Find the value of the function y = 3x^2 - 21 when x = 4.
y = __
y = __
y = 3(4)^2 - 21
y = 3(16) - 21
y = 48 - 21
y = 27
Therefore, the value of the function y = 3x^2 - 21 when x = 4 is 27.
y = 3(16) - 21
y = 48 - 21
y = 27
Therefore, the value of the function y = 3x^2 - 21 when x = 4 is 27.
When the input is x = 0.3, which of the following is the output of the function y = 3x + 6?
A. 6.3
B. 6.9
C. 0.3
D. 9
A. 6.3
B. 6.9
C. 0.3
D. 9
y = 3(0.3) + 6
y = 0.9 + 6
y = 6.9
Therefore, the output of the function y = 3x + 6 when x = 0.3 is 6.9, which corresponds to option B.
y = 0.9 + 6
y = 6.9
Therefore, the output of the function y = 3x + 6 when x = 0.3 is 6.9, which corresponds to option B.
What is the value of the function y = 1/8x - 13 = -4?
A. -15
B. -16
C. -12.5
D. -13.5
A. -15
B. -16
C. -12.5
D. -13.5
To solve for the value of x in the equation y = 1/8x - 13 = -4, you first need to substitute y = -4 into the equation and then solve for x:
-4 = (1/8)x - 13
Add 13 to both sides:
-4 + 13 = (1/8)x
9 = (1/8)x
Multiply by 8 to both sides to get rid of the fraction:
8(9) = x
x = 72
Therefore, the value of x in the equation y = 1/8x - 13 = -4 is x = 72.
However, it seems like the options provided do not match the calculated answer of x = 72. Let me know if there is a mistake in the interpretation of the question or if a different calculation is required.
-4 = (1/8)x - 13
Add 13 to both sides:
-4 + 13 = (1/8)x
9 = (1/8)x
Multiply by 8 to both sides to get rid of the fraction:
8(9) = x
x = 72
Therefore, the value of x in the equation y = 1/8x - 13 = -4 is x = 72.
However, it seems like the options provided do not match the calculated answer of x = 72. Let me know if there is a mistake in the interpretation of the question or if a different calculation is required.
choose 1 please
Based on the options provided and the calculation performed, the value of the function y = 1/8x - 13 when y = -4 would be:
