Awnswer:
y=-19x+(the y intercept)
Step-by-step explanation:
y=mx+b
m(slope)=rise/run
(-11,-12) (-8,-21)
-21-12/-8-11
-33/-19
y=-19x+b
(You didn't add what the y intercept was, so you'll have to do that part when you awnswer.) :)
Answer: C
Step-by-step explanation:
f(x) = x² and g(x) = x + 1
This is composite function, i.e function of a function
g(f(x)) = g(x²), since f(x) = x²
f(-2) = (-2)² = 4
g(f(-2)) = g(4) = 4 + 1 = 5
You can set up an inequality to solve this. You can either do big to small --> or small to big --> . I'm going to be using big to small because I think it's a little easier.
Cross multiply and you will get:
Isolate x:
x =
x = 45
