A) 4(25-3y)+5y=9
100-7y=9
91=7y
y=13
(-14,13)
b) 14-x=x-10
2x=24
x=12
(12,14)
c) 4x=12
(3,7)
d) 18.5x+10.4y=200
x+y=130
Answer:
y = 17x
Step-by-step explanation:
Buying price: $75,300
Selling price: $80,250
You want to find out how much more the selling price was when compared to the buying price.
To find the difference in prices, simply subtract the selling price with the buying price.
$80,250 (buying price) - $75,300 (selling price) = $4,950 (price difference)
The selling price is greater than the buying price of the house by $4,950

Answer:
(2, 2 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ 
(x₁ + x₂ ) , (y₁ + y₂ ) ]
Here (x₁, y₁ ) = (A(5, 8) and (x₂, y₂ ) = B(- 1, - 4) , thus
midpoint = [ (5 - 1), (8 - 4 ) ] = (2, 2 )
