On a coordinate plane, an absolute value graph has a vertex at (negative 1, negative 3). Which function is represented by the graph?

f(x) = |x – 1| + 3
f(x) = |x + 1| – 3
f(x) = |x – 1| – 3
f(x) = |x + 1| + 3

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
