Answer:
10 inches tall in the 5th week
Explanation:
It looks like Melissa's equation, y = 2x, is a good representation of her tomato plant's growth. In this equation:
- "x" represents the number of weeks that have passed.
- "y" represents the height of the tomato plant in inches.
The equation y = 2x reflects the doubling pattern you mentioned. Each week, the height of the plant doubles from the previous week's height. This is a simple and accurate way to predict the height of her tomato plant at any given week, assuming the doubling pattern continues.
For example, if you want to know how tall the plant will be in the 5th week (x = 5), you can plug this value into the equation:
y = 2x
y = 2(5)
y = 10
So, the tomato plant would be 10 inches tall in the 5th week according to this equation.
