F(x) = 2-4x; f(-5) a. 25 b. -22 c. 21 d. 22 pls like now

We are told that f(x) = 2 - 4x and we want to find f(-5).

To do this, we put -5 in for x in all places on both sides of the equals sign. The left side tells us the input while the right side tells us the output.

f(x) = 2 - 4x

f(-5) = 2 - 4(-5)      < notice how x and - 5 match

f(-5) = 2 - (-20)      by applying the multiplication of 4 and -5

f(-5) = 2 + 20        by applying the parentheses

f(-5) = 22

Thus, f(-5) is 22 and choice D is best.

u bout ugly as   a mf

step-by-step explanation: lol

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to
