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.
Answer (Note: the bold are answers):
First question answer:
Point = (3,1)
Slope = 3
y = 3x + b
(1) = 3(3) + b
1 = 9 + b
1 - 9 = b
-8 = b
y = 3x - 8
The second question answer:
y = mx + b
Get two points:
(3,-7) and (4,-11)
m = -11 - (-7) / 4 - 3
m = -11 + 7 / 1
m = -4 / 1
m = -4
b = + 3
y = -4x + 3
You will get paid $323.75 if you work 35 hours and get paid $9.25 per hour
The answer would be 16 3/4 divided by 3 7/8
