Question

Evaluate –x + 2.7 for x = 0.9. A. –1.8 B. –3.6 C. 1.8 D. 3.6

Answer 1

Option C is the correct answer.

Step-by-step explanation:

Here we need to evaluate –x + 2.7 for x = 0.9.

That is f(x) = –x + 2.7 and we need to find f(0.9).

                f(x) = –x + 2.7

                f(0.9) = –0.9 + 2.7

                f(0.9) =  2.7 - 0.9

                f(0.9) = 1.8

Option C is the correct answer.

Answer 2

C.1.8 because -0.9+2.7 is equal to 1.8
