Evaluate the algebraic expression 9 + 3(x - 2) for x = 5. Evaluate the algebraic expression for the given values of the variables. N x2 - 3(x - y). for x = 10 and y = 1 W The formula C = (F - 32) expresses the relationship between Fahrenheit temperature, F, and Celsius temperature, C. Use the formula to convert 41OF to its equivalent temperature on the Celsius scale. A football is kicked vertically upward from a height of 2 feet with an initial speed of 60 feet per second. The formula h = 2 + 60t - 161" describes the ball's height above the ground, h, in feet, t seconds after it was kicked. Use this formula to find the ball's height 3 seconds after it was kicked.
