Question

Evaluate –x + 2.7 for x = 0.9.

A. –1.8

B. –3.6

C. 1.8

D. 3.6

Answer 1

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

Answer 2

Option C is the correct answer.

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.
