A ball is thrown vertically upward. After t seconds, its height h, in feet, is given by the function h (t) = -16t^2 + 64t. How many seconds will it take the ball to reach its maximum height?

Find the quotient. 50a2 – 98b2 -5a +7b

Which of the following equations is equivalent to x/3-6/x=1

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
