Question

Kristin bought two sunflower plants. Plant A is 8 inches tall and is growing at a rate of 3 inches per week. Plant B is 12 inches tall and is growing at a rate of 2 inches per week. Write the two equations to represent each sunflower plant if the plants to continue to grow at the same rate. In your equations, x

represents the number of weeks, and y
represents the height of the plant in inches. (1 point)
Plant A: y=

Plant B: y=

Question 2
When will the plants be exactly the same height?

This question requires you to show your work.

(1 point)
The plants will be exactly the same height during week
.

Answer 1

Plant A: y = 8 + 3x

Plant B: y = 12 + 2x

To find when the plants will be exactly the same height, set the two equations equal to each other:

8 + 3x = 12 + 2x

Subtract 2x from both sides:

x = 4

Therefore, the plants will be exactly the same height during week 4.
