Answer:
Y=7+3x, x=-3, y=-2
Step-by-step explanation:
3x-5y=1. Equation 1
3x-y=-7. Equation 2
-y=-7-3x isolate for y in equation 2
y=7+3x multiplied by -1 to get positive y
3x-5(7+3x)=1 substitute y value of equation 2 (7+3x) into equation 1
3x-35-15x=1
-12x=36
x=-3
solve for y.
3x-5y=1
3(-3)-5y=1
-9-5y=1
-5y=10
y=-2
3/2^2 or 0.75 because you have to take the middle value (3), divide it in half, then square it. That would be 0.75.
Answer:
Uh yeah Its right...i think
Just make sure if its right
X=4 y=10
Because when you look at the intersection of the two lines they intersect at (4,10) (x,y)
