Answer: F(x) = 5x^2 + 10x
Answer:
f(2)=-15
Step-by-step explanation:
y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.
.7X+.25*100=.6(100+X)
.7X+25=60+.6X
.7X-.6X=60-25
.1X=35
X=35/.1
X=350 GALLONS OF 70% ANTIFREEZE WILL BE NEEDED.
