Using the given linear function of best-fit, the most likely approximate height of the plant after 8 weeks would be of 7.4 centimeters.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
The line of best-fit goes through points (0,1) and (5,5). Point (0,1) means that the y-intercept is of b = 1. The slope is given as follows:
m = (5 - 1)/(5 - 0) = 4/5 = 0.8.
Hence the equation that gives the approximate height after x weeks is:
y = 0.8x + 1.
After 8 weeks, the expected height is:
y = 0.8 x 8 + 1 = 6.4 + 1 = 7.4 centimeters.

<u>Answer:</u>
One cookie is $1.72
<u>Step-by-step explanation:</u>
So. We are given a bit of information here that we must process. The biggest things we need to know are:
A cupcake= $2.75
24 Cookies in Total=?
Total Bill= $44.03
So, at this point in time, we can set up our equation with what we know, where our ? will equal X.
$2.75+X=$44.03.
This is a simple one step equation. We are going to subtract $2.75 from both sides, which cancels out on the left, and leaves:
X= $41.28
Now that we know the total of the cookies without the cupcakes, we can now set up a new equation such as: (The 24 comes from the number of cookies Mr.Perkins bought).
$41.28/24=?
Now divide.
Each cookie costs $1.72
Answer:
72:48
Step-by-step explanation:
as you divide 120 by 5 as 3+2=5 and that equals 24
24x3=72
24x2=48
