To find when the two plants will be the same height, we can set the two equations equal to each other and solve for x:
For Plant A:
y = 8 + 3x
For Plant B:
y = 12 + 2x
Setting the two equations equal to each other:
8 + 3x = 12 + 2x
Solving for x:
3x - 2x = 12 - 8
x = 4
Therefore, the two plants will be exactly the same height after 4 weeks.
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=
=
