Ok here it is:
4x-5y=40
2x+10y=20
I used the second equation and decided to get x
2x+10y=20
Subtract 10y from both sides.
2x=-10y+20
Divide both sides by 2
x=-5y+10
Put that in for x for first equation
4(-5y+10)-5y=40
Distribute the 4
-20y+40 -5y =40
Combine like terms
-25y+40=40
Subtract 40 from both sides
-25y=0
Divide by -25 on both sides
y=0
Substitute the y in for the 2nd equation
2x+10(0)=20
2x=20
Divide both sides by 2
x=10
So x=10 and y=0
Answer:
The maximum value of the range is 4.
The range of g(x) is {-1 < y ≤ 4}.
Step-by-step explanation:
The range refers to the set of y - values the linear piecewise function contains, which would be {-1 < y ≤ 4}.
The domain refers to the set of x - values the linear piecewise function contains, which would be {-4 ≤ x < 3}.

Answer: $163.85
Explanation:
1) Data:
Purchase price: $ 113.00
mark up: 45%
2) Formula
selling price = purchase price + mark up
mark up = % * purchase price
3) Solution
mark up = 45% * $ 113.00 = 0.45 * $ 113.00 = $50.85
selling price = $ 113.00 + $ 50.85 = $ 163.85
Answer: $ 163.85
