It is the fourth option, y+8=3(x-8)
Answer:
x -7
Step-by-step explanation:
f(x)=-3x-5
g(x)=4x-2
(f+g)(x)= -3x-5+4x-2
Combine like terms
= -3x+4x -5-2
= x -7
D= 140° because you take 180 minus the opposite angle
X^2+19x+90
You distribute each number to each other then at the end add the common terms together. Also you add the x’s exponents when distributing or multiplying.
