Answer:
Kameron has 5 quarters in his wallet
Step-by-step explanation:
Let
x----> the number of nickels
y----> the number of quarters
remember that
1 nickel=$0.05
1 quarter=$0.25
we know that
x=3y -----> equation A
0.05x+0.25y=2
Multiply by 100 both sides
5x+25y=200
Simplify
x+5y=40 -----> equation B
Substitute equation A in equation B
(3y)+5y=40
8y=40
y=5 quarters
x=3(5)=15 nickels
Answer:
y=12x-125
Step-by-step explanation:
y=12x+3
parallel lines have same slopes,
y-y1=m(x-x1)
y-(-5)=12(x-10)
y+5=12x-120
y=12x-120-5
y=12x-125
It should look like a vertical line on the 2 of the x axis and everything to the right would be shaded.
