Y is directly proportional to x ^2 . If y = 45 when x = 3 find x when y = 180

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 =

Sove the equation 6c + 11 = 2c + 59
