Answer:
1. -7.5
2. $1
3. 40
Step-by-step explanation:
For number 1, it can be solved by using the PEMDAS method, or see explanation below:
6x - 4x - 36 = 6 - 2x
2x - 36= -2x + 6
4x + 36 = 6
4x = -30
x = -15/2 or -7.5
For number 2, substitute 3 into both equations:
f(x) =1.50(3) + 2.00
and
f(x) = 2.00(3) + 1.50
This would get $6.50 and $7.50, which, if subtracted, gets $1.
For number 3, do something similar to the previous problem. Substitute 3 for x. It would be 5(2^3), or 40.
Hope this helps!

Step-by-step explanation:180-38
Answer:
5x-y=50
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are the same
In this problem
The west edge of the basketball court is located on the line
y = 5x + 2 -----> the slope of this line is m=5
If the east edge cannot intersect with the west edge
then
east edge and west edge must be parallel
so
The east edge could be
5x-y=50
because
y=5x-50 ----> the slope of this line is m=5
