The axis of symmetry for parabola is x = 3.
Using derivative to solve for axis od symmetry is easier.
Step-by-step explanation:
the the equation used is take 1000 marbles - 243 marbles then you'll surely get your answer
Answer:
Whoa, that's a lot to answer...
15. 30000=500x
16. y=58x+5
in 16, the total cost is y, so y has to be in 1 side for itself. and we need to add the amount of tickets and the fee (5$). So we get that equation.
|r+3| = (r+3) when r ≥ -3 so for r ≥ -3
r + 3 ≥ 7
r ≥ 4
|r+3| = -(r+3) when r < -3 so for r < -3
-(r + 3) ≥ 7
r + 3 ≤ -7
r ≤ -10
The answer to this question is r ≤ -10, r ≥ 4
