The perimeter of a rectangle is 138 meters and the area is 1080 square
meters. Find the length and the width of
the rectangle.

The variable z is directly proportional to x, and inversely proportional to y. when x is 4 and y is 13, z has the value 1.2307692307692. what is the value of z when x= 9, and y= 20

Which graph corresponds to the function f(x) = x2 + 4x – 1?
