4 .

y = (½) x

The bottom of a vase is a square.each side measury y+11 units.the square has a perimeter of 55 units what is the value of y?

Quick use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit. {f(x) = x - 6 / -x² + 8 {g(x) = i x i (dont know how to add an image) select all that apply. (-3.3, 3.3) (3.3, -3.3) (3, -3) (3, 3) (-3, -3) (can select multiple)

Ineed stat i need this to be simplified! 9(5x)
