Describe the transformation that took place if f(x)=x? became f (x) = 0.2(x - 5)2 – 2

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

How many solutions does the nonlinear system of equations graphed bellow have?

Will give a: 122 b: 90 c: 48 d: 180
