Commutative Property
5x + 5y = 5(x+y)
-2x = y^5 or y^5 = -2x y = (-2x)^(1/5)
If you mean 7-y = 5 then y = 2
y^5/2
y5 * y3 * y = y5 * y3 * y1 = y5+3+1 = y9
It is an algebraic expression for 9 reduced by 5 times y.
If you mean x-y = 5 then y = x-5 whereas it has a slope of 1 and a y intercept of -5
y-5 = 32 y5 = 1/32 and so y = 1/2
7
y2 * y-5 = y2 / y5 = 1/y3
If y = 5 then there is no slope because the line is parallel to the x axis
If you mean: 3x-y=5 then y=3x-5 and the perpendicular equation is y=-1/3x-7
