Well, let's see that we can find the midpoint with this formula:
We have the midpoint and one of the endpoints so:
We have this now:
So the pair is (0, -37)

System of Linear Equations entered :
[1] x + 2y = 5
[2] x - y = 4
Graphic Representation of the Equations :
2y + x = 5 y + x = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = y + 4
// Plug this in for variable x in equation [1]
[1] (y +4) + 2y = 5
[1] 3y = 1
// Solve equation [1] for the variable y
[1] 3y = 1
[1] y = 1/3
// By now we know this much :
x = y+4
y = 1/3
// Use the y value to solve for x
x = (1/3)+4 = 13/3
Solution :
{x,y} = {13/3,1/3}
X=-2
In standard form:
x=2^-1
Hope this helps :)
Answer:
40% discount
Step-by-step explanation:
Take the original price and subtract the new price
20-12
The discount is 8
Divide the discount by the original price
8/20 =.4
Multiply by 100 to get the percent
.4 * 100 = 40%
There is a 40 percent discount
