Given the definitions of f(x) and g(x) below, find the value of (f og)(-1). f(x) = -x + 3
g(x) = 2x2 + x - 9

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
