Kristen bought two sunflower plants plant is 8 inches tall and is growing at a rate of 3 inches per week Plan B is 12 inches tall and is growing at a rate of 2 inches per week right two equations to represent each sunflower plant of the plants to continue to grow at the same rate and your equations X represents the number of weeks and wire represents the height of the plant in inches when will the plants be exactly the same height
For plant A:
y = 8 + 3x
For plant B:
y = 12 + 2x
To find when the plants will be 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 after 4 weeks.
