(2x+3)^5 expanded using binomial theorem

Subscriptions to a popular fashion magazine have gone down by a consistent percentage each year and can be modeled by the function y = 42,000(0.96)t. what does the value 42,000 represent in the function?

Write the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7. t

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28
