Answer:
1. 6x − 6 at x = 3
= 6(3) - 6
= 18 - 6
= 12
Answer: A. 12
2. 6x − 1 at x = −10
= 6(-10) - 1
= -60 - 1
= -61
Answer: B. -61
3. 12x + 10 at x = 2
= 12(2) + 10
= 24 + 10
= 34
Answer: C. 34
4. −6x + 7 at x = 11
= -6(11) + 7
= -66 + 7
= -59
Answer: D. -59
5. −9x − 5 at x = −2
= -9(-2) - 5
= 18 - 5
= 13
Answer: E. 13
