Answer:
m<A = 65
Step-by-step explanation:
(4x-3) + (x+8) = 90
5x + 5 = 90
5x = 85
x = 17
m<A = 4(17) - 3
68 - 3 = 65
Answer:
-12
Step-by-step explanation:
What it means by f(-1) is that x is -1.
So all you do is plug -1 into the x areas like this: -3(-1)^2+2(-1)-7=-12.
Y= 3.5t+2
you spent 3.5 hours on each test
(3.5(4)+2= 16)
