By setting up a system of equations we can easily solve this problem. Let's denote Jane's working hours with x and Jack's working hours with y. Since they don't want to work more than 65 hours, the first equation is x+y=65. The second equation is 14x+7y=770. By solving this system of equation

, we find that y=20 hours, which is Jack's maximum working hours.
Answer a^3-3a
a^2 times a = a^3 you add exponents
Answer:
Step-by-step explanation:
rise over run
from the bottom to where the point is
From (0,0) to (4,3)
you rise 3 and run 4
So I think the Slope is 3/4
Answer:
m = -1/2
Step-by-step explanation:
m = y1 - y2/x1 - x2
2 - 0/0 - 4
-2/4
Simplify
-1/2
