How do you solve 4y+18=20

What does the relationship between the mean and median reveal about the shape of the data

After t seconds, a ball tossed in the air from the ground level reaches a height of h feet given by the equation h = 144t-16t^2. after how many seconds will the ball hit the ground before rebounding?

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5
