If f(x) = x^2 and g(x) = 1/2x + 3, find g(f(-1)). A.) -1 B.) 1/25 C.) 1/5 D.) 1

1 answer:

5 0

F(x)=x^2
x=-1→f(-1)=(-1)^2→f(-1)=1

g(x)=1/(2x+3)
g(f(-1))=g(1)→x=1→g(1)=1/[2(1)+3]=1/(2+3)→g(f(-1))=1/5

Answer: Option C.) 1/5

Answer:

m∠ TRS = 60° , m∠ SRW = 120°

Step-by-step explanation:

First, find x

∠TRS = ∠VRW (vertically opposite angles are equal)

x + 40° = 3x

x - 3x = -40

-2x = -40

x = -40/-2

x = 20

m∠ TRS = 60° [x + 40 = 20+40 = 60]

m∠ SRW + m∠ TRS = 180° (linear pair)

m∠ SRW + 60° = 180°

m∠ SRW = 180° - 60°

m∠ SRW = 120°

hope this helps you
