Question

You plant an 8-inch-tall tomato plant that grows 5 inches taller each week. On the same day, you plant a 14-inch-tall tomato plant that grows 3.5 inches taller each week. Graph a system of equations that represents the heights y (in inches) of the plants after x weeks. Use the graph to solve the system.

Answer 1

y = 5x + 8

y = 3.5x + 14

You need to graph each equation on the same graph paper and see where the two lines cross. That point is your answer.

I will give you a start.
The first graph has a point (0,8) and the second graph has a point (0, 14)

Find two more points for each graph and that will help you find your lines.

Answer 2

UGHHH none of these help this poor 8th grader out heller

Answer 3

You have a total of 45 dimes and quarters. You have 3 more quarters than dimes. Which system of equations can you use to find the number x of quarters and number y of dimes you have? Use the system to determine how much money you have in quarters and dimes.

I'm really confused o how to do this.

Answer 4

Bruh can y’all just help… jus gimme the answer. You plant an 8-inch-tall tomato plant that grows 5 inches taller each week. On the same day, you plant a 14-inch-tall tomato plant that grows 3.5 inches taller each week. Graph a system of equations that represents the heights y (in inches) of the plants after x weeks.
