Substitute x with 3.

f(3) = |4(3)^2 - 3(3)|

f(3) = |4(9) - 9|

f(3) = |36 - 9|

f(3) = |27|

f(3) = 27

Absolute Value keeps the number positive regarding it's sign.

Hope This Helped! Good Luck!

X-intercept mean y=0

2/5x+1/10(0)=2

2/5x=2

X= 5

X-intercept = (5,0)

Y-intercept means x= 0

2/5(0)+1/10y=2

1/10y=2

y=20

Y-intercept = (0,20)

emilio had $150 on a gift card he used the gift card to purchase 8 dvds. adam had $175 on a gift card and used the gift card to

Artyom0805 [142]

150 - 8d = 175 - 10d
-8d + 10d = 175 - 150
2d = 25
d = 25/2
d = 12.5...so each dvd costs 12.50

150 - 8(12.5) = 150 - 100 = 50
175 - 10(12.5) = 175 - 125 = 50

so they will each have 50 bucks left on their card
