A) 4*N -Q = 0
B) .05N + .25Q = 2.10
Multiply B) by 4
B) .2N + Q = 8.40 Adding this to A)
A) 4*N -Q = 0
4.2N = 8.40
N = 2 Nickels
Q = 8 Quarters
Answer:
A
Step-by-step explanation:
slope is rise over run 4/1 so the slope is 4 and intercept is 3.
Answer:
The correct option is A.
Step-by-step explanation:
The given equation is

Put x=0, in the given equation.

The y-intercept is (0,32).
Put y=0, to find the x-intercept.





Therefore the y-intercepts are (-4,0) and (8,0).
The vertex of a parabola
is


Put x=2 in the given function.



The vertex is (2,36).
Therefore option A is correct.
