Let f(x) = -2x - 7 and g(x) = -4x + 6. Find (g . f)(-5)

26

3

–59

–6

–59

Step-by-step explanation:

f(x) = -2x - 7

f(x) = -2(-4x + 6) - 7

f(x) = 8x - 12- 7

f(x) = 8x - 19

f(x) = 8(-5) - 19

f(x) = -40 - 19

f(x) = -40 - 19

f(x) = - 59

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
