Answer:
Width=75
length=105
Step-by-step explanation:
Width=x
length=30+x
= 7875=x*30+x
x^2+30x-7875=0
x^2+105x-75x-7875=0
x(x+105)-75(x+105)=0
this relation is a function, y=30x
for every ax or 1 gallon, it goes 30 miles.
Answer:
Step-by-step explanation:
h(g(2)) = h( 2²) = h(4) ; because g(x=2) = 2²
h(4) = 5*4+1 = 21
Answer: B. Exponential. There is a constant rate of decay or decrease.
The y-values decrease by 1/4 of the number that comes before every time.
