Answer:
15%
Step-by-step explanation:
set up 15/20= x/100
cross multiply to solve for x
1500=20x
x= 75
15 dollars is 75% of the original price, so there was a 15% change
Step-by-step explanation:
A function f(x) can be scaled by a factor of "a" and translated by (h,k) by the relation:
f(x) -> a f(x-h)+k
substitute f(x) by sqrt(x), then
sqrt(x) -> a*sqrt(x-h) + k
So the given equation is derived from f(x) = sqrt(x), hence a radical function.
To get y you can move the x's to one side, so 120y=500-35x
then you can isolate the y, y= 500/120-35x/120
