Question

A plant is already 42 centimeters tall, and it will grow one centimeter every month.Let H be the plant's height (in centimeters) after M months.Write an equation relating H to M. Then use this equation to find the plant's helght after 35 months.Equation:D-ORХ5?Plant's height after 35 months: centimeters

Answer 1

write the height of the plant after m months as a linear function in which the y-intercept is the plant's initial height (42 cm) and the slope is the growth the plant experiences after each month (1 cm)

`H=M+42`

then, after 35 months

`\begin{gathered} H=35+42 \\ H=77 \end{gathered}`

The plant's height after 35 months is 77 cm.
