Answer: -27/7
Step-by-step explanation:
Answer:
I believe the reflection line will be on x=1
Step-by-step explanation:
I tend to eyeball the reflection line to make it symmetrical, if I'm not much of a help I apologize
Z(x)=6x^3+19x^2-52x+15
(6*-5)^3+19*-5^2-52*-5+15
Z(x)= -17,700
Initial charge charged by the Singer A = $50
Hourly charge of Singer A = $20
Initial amount charged by Singer B = $100
Hourly rate charged by Singer B = $10
Let us assume the time after which both singers will charge the smae amount of money = x
Then
50 + 20x = 100 + 10x
20x -10x = 100 - 50
10x = 50
x = 50/10
= 5
So after 5 hours both Singer A and Singer B will charge the same amount of money. I hope the procedure is clear to you and you can attempt such problems in future without needing any kind of help.
