Answer 1

C: 6

Explanation:

Answer 2

C) 6 inches

Explanation:

Given function:

`Y=1.3x-0.8`

The function compares plant height in inches to the age of plant in weeks.

So, we can say

`Y` represents height of plant in inches.

`x` represents age of the plant in weeks.

In order to predict the height of the plant in 5 weeks, we will plugin
`x=5` in the given function and evaluate
`Y`

⇒
`Y=1.3(5)-0.8`

⇒
`Y=6.5-0.8`

⇒
`Y=5.7` inches

Thus the approximate height of plant in 5 weeks would be
`\approx 6` inches
