Jack bought a tree to plant in his front yard. The tree grows at an approximate rate of 9 inches per year. After 4 years the tree is at 5 feet tall. Write an equation in slope intercept form to find the hight (in feet) of the tree, y, after x years. Then, find the number of years it will take the tree to reach 20 feet

What does it mean by solve the exponential equation for x?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

If you flip a coin 3 times, what is the probability of flipping heads 3 times? a. p(3 heads) = 3/8 b. p(3 heads) = 1/6 c. p(3 heads) = 1/8 d. p(3 heads) = 1/2
