Plant A: y = 8 + 3x
Plant B: y = 12 + 2x
To find when the plants will be exactly the same height, we set the two equations equal to each other:
8 + 3x = 12 + 2x
Subtract 2x from both sides:
8 + x = 12
Subtract 8 from both sides:
x = 4
Therefore, the 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
Plant A: y = ____
Plant B: y = _____
When will the plants be exactly the same height?
