Answer:


18.5\operatorname{cm}

Step-by-step explanation:

Given that today the plant is 5 cm high.


h_0=5\operatorname{cm}

the plant grows 1.5 per day;


\text{rate = 1.5 cm/day}

Let x represent the number of days;

The height of lynn's plant after x days is;


h_x=1.5x+5

after 9 days;


x=9

substituting;


\begin{gathered} h=1.5(9)+5 \\ h=18.5\operatorname{cm} \end{gathered}

Therefore, lynn's plant is 18.5 cm tall after 9 days,
