-5x=-25
Divide by -5
x=5
3x-2(x+5)=-3+18

3x-2(x+5)=15
3x-2x-10=15
x-10=15

x=25
assuming 10 numbers ( 0-9)
and 26 letters (A-Z)
10^4 x 26^2 = 6,760,000
Hello :
x =(1/4)y²
<span> the coordinate point for the vertex is : O ( 0, 0)</span>
To find slope you do y2-y1 over x2-x1. So 4-6 is -2. And 3-1 is 2. So -2/2 is -1. The slope is -1.
