Answer: 60 hours
(I'll help you with the first one only because you need to learn this)
Step-by-step explanation: 36 divided by 3 is 12 and 720 divided by 12 is 60
If it was reflected over the x-axis it would become (4,-3).
X*y=72
x = 5y-2
x=72/y
72/y=5y-2
72=5y^2-2y
5y^2 -2y - 72 = 0
(5y+18)(y-4)=0
y = -18/5 discard
or y = 4
4x=72
x=18
(18,4)
Answer:
x y
0 .75
3 3.75
9 9.75
Step-by-step explanation:
You add .75 to whatever number x equals, to get y.
