Kristen bought two sunflower plants plant a is 8 in tall and is growing at a rate of 3 in per week plant B is 12 in tall and is growing at the rate of 2 in per week right 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 why represents the height of the plant in inches plant a y equals? Plant b y equals? When will the plants be exactly the same height during what week
For plant A:
y = 8 + 3x
For plant B:
y = 12 + 2x
To find when the two plants will be the same height, we set the two equations equal to each other:
8 + 3x = 12 + 2x
Subtracting 2x from both sides:
x = 4
Therefore, the plants will be the same height in the 4th week.
