Answer:
D. -15
Step-by-step explanation:
f(x)=7
f(x) = -3x + 6
Then substitute x for 7 and solve linearly.
-3(7)+6
-21+6
=-15
The answer is D
Answer:
x = 120-95
Step-by-step explanation:
The correct equation for the expression is:
∠AFC = ∠AFB+ ∠BFC
Given that
∠AFC = 120°
∠BFC = 95°
Substitute
120= ∠AFB+95
∠AFB = 120-95
If ∠AFB = x
The required equation will be:
x = 120-95
