Olivia needs $36 to buy a coat. She has saved $8 and plans to work as a babysitter to earn $7 per hour. Which inequality shows the minimum number of hours, n, that Olivia should work as a babysitter to earn enough to buy the coat? 8 + 7n ≤ 36, so n ≤ 4 8 + 7n ≥ 36, so n ≥ 4 7n ≥ 36 + 8, so n ≥ 6.3 7n ≤ 36 + 8, so n ≤ 6.3

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
