In a study a researcher measured a plant to be 8 cm tall. If the plant continues to grow 2 cm every week, after how many weeks will the plant reach the height of 24 cm?

8 weeks

Step-by-step explanation:

Given

weekly

Required

Determine the duration it gets to 24 weeks

First, we need to represent the scenario as a function.

Let the number of weeks be w.

So:

f(w) = Initial Height + Growth * Number of Weeks

This gives:

When the duration is 24 weeks,

We have that:

Substitute 24 for f(w)

Make 2w the subject of formula

Make w the subject of formula

Hence, it'll take the plant 8 weeks to get to 24cm

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
