Answer:
36 quarters 48 dimes 64 nickels
Step-by-step explanation:
quarter = q
dime = q+12
nickel = 2q-8
$17 = 1,700 cents
(q)25 + (q+12)10 + (2q-8)5 = 1,700
25q +10q+120 +10q-40 =1,700
45q+80 = 1,700
45q = 1620
q= 36
36 QUARTERS x25 = 900cents
48 DIMES x10 = 480 cents
64 NICKELS x 5 = 320 cents
TOTAL 1,700 cents ($17)
We can use the Front Outside Inside Last (FOIL) method to expand the double bracket
![(3x+5)(5x-1)](https://tex.z-dn.net/?f=%283x%2B5%29%285x-1%29)
Front ⇒
![(3x)(5x)=15 x^{2}](https://tex.z-dn.net/?f=%283x%29%285x%29%3D15%20x%5E%7B2%7D%20)
Outside ⇒
![(3x)(-1)=-3x](https://tex.z-dn.net/?f=%283x%29%28-1%29%3D-3x)
Inside ⇒
![(5)(5x)=25x](https://tex.z-dn.net/?f=%285%29%285x%29%3D25x)
Last ⇒
![(5)(-1)=-5](https://tex.z-dn.net/?f=%285%29%28-1%29%3D-5)
Put the four terms together we have
![15 x^{2} -3x+25x-5](https://tex.z-dn.net/?f=15%20x%5E%7B2%7D%20-3x%2B25x-5%20)
, then collect like terms

Step-by-step explanation:
according to the drawing,
for x = 0 => y = 12
the coordinates of y-intercept : (0, 12)
so, y = f(0) = 12
The correct answer is 12 only
