Let g(x) = 8 - x + 6x Evaluate g(5)
- A.
27
- B.
33
- C.
28
- D.
-27
Correct Answer
B. 33Explanation
The given function is g(x) = 8 - x + 6x. To evaluate g(5), we substitute x = 5 into the function. g(5) = 8 - 5 + 6(5) = 8 - 5 + 30 = 33.Rate this question:

- B.
9
- C.
-3
- D.
21
Correct Answer
C. -3Explanation
The function h(x) is not given, but we are asked to evaluate h(16). The answer given is -3. This suggests that when x is equal to 16, h(x) is equal to -3.Rate this question:

- B.
-5
- C.
13
- D.
21
Correct Answer
D. 21Explanation
To solve the function h(x) = -2x + 13 for x = -4, we substitute x = -4 into the function. By substituting the value, we get h(-4) = -2(-4) + 13 = 8 + 13 = 21. Therefore, the correct answer is 21.Rate this question:
