N-nickels, q-<span>quarters

n+q=13=>n=13-q

0.25q+0.05n=2.25
0.25q+0.05(13-q)=2.25
0.25q+0.65-0.05q=2.25
0.20q=2.25-0.65
0.20q=1.6
q=1.6:0.2
q=8
n=13-8
n=5

Why does a y-intercept not count as a zero?
Genrish500 [490]

Answer:

It only counts as a zero when the y-intercept is (0,0).

Step-by-step explanation:

The zeros of a quadratic function are always written as (x,0), while the y-intercept is always written as (0,y). Therefore, in order for a y-intercept to be a zero, it must be (0,0), because the y-coordinate in any zero is 0. At any other time, the y-intercept is not a zero.
