Hi there!
Let the amount of hours Kim worked be represented by X.
Her total earnings on a Friday night can be expressed as $30 + ($1.25 × the amount of hours). We can now set up a function for her total revenue (represented by Y).

When Kim works 3 hours we need to plug in x = 3 into the formula.

Therefore, after 3 hours of working, Kim would have made $33.75

Let the two numbers be x and y.
The sum is 45, therefore
x + y = 45 (1)
The difference is 5, therefore
x - y = 5 (2)
Add equations (1) and (2).
x + y + (x - y) = 45 + 5
2x = 50
x = 25
From (1), obtain
25 + y = 45
y = 45 - 25 = 20
Answer: 20 and 25
slope = change in height/change in time
(0,6) (2,3)
= (6-3)/ ((0-2)
= 3/-2
=-3/2
The slope is -3/2
