Hey!
-------------------------------------------------
Prefect Pipes: 120 + 40 = $160 (y-intercept)
No Leaks Here: 50 + 60 = $110 (y-intercept)
-------------------------------------------------
Hour #1:
Prefect Pipes: 160 + 40 = $200
No Leaks Here: 110 + 60 = $170
Hour #2:
Prefect Pipes: 200 + 40 = $240
No Leaks Here: 170 + 60 = $230
Hour #3:
Prefect Pipes: 240 + 40 = $280
No Leaks Here: 230 + 60 = $290
-------------------------------------------------
$280 < $290
After 3 hours Perfect Pipes is less expensive than No Leaks Here!
-------------------------------------------------
Hope This Helped! Good Luck!
The fill in the blanks is missing a ^2 because it is a completing of squares so it's missing something but the answer is:
y = (x+4)^2 +9
Answer:
THERE YA GOO BROSKI
Step-by-step explanation:
4 x (25 + 4)
4 * 25
4 * 4
(4 * 25) + ( 4 * 4 ) = Distributive Property
4 * 25 = 100
4 * 4 = 16
100 + 16 = 116
*When dividing with a negative, the sign changes directions.
The 4th option would be correct.
{X | - Root 5 < x < Root 5 }
