to get the equation of any straight line, we simply need two points off of it, so let's use the points in the picture below.

now, if we use the last point from the table, namely (x , 17), we can see that x = x and y = 17, so let's plug those in the equation
![(17)-5=2(x-1)\implies 12=2x-2\implies 14=2x\implies \cfrac{14}{2}=x\implies 7=x \\\\[-0.35em] ~\dotfill\\\\ ~\hfill (7~~,~~17)~\hfill](https://tex.z-dn.net/?f=%2817%29-5%3D2%28x-1%29%5Cimplies%2012%3D2x-2%5Cimplies%2014%3D2x%5Cimplies%20%5Ccfrac%7B14%7D%7B2%7D%3Dx%5Cimplies%207%3Dx%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20~%5Chfill%20%287~~%2C~~17%29~%5Chfill)
Answer:
The perimeter of the first question is 62
If you draw it, you'll you'll see that it's a rectangle. The length of each side is calculated by adding the widths and heights as in the photo ( red ), and then adding them up. 13 + 18 + 13 + 18 = 62
You do the same with question 2, but this time the rectangle is smaller. (green in the photo)
So the perimeter is:
13 + 14 + 13 + 14 = 54
The answer to question 3 is (-15, -5) as drawn in the photo.
Answer:
12 pencils in each package.
Step-by-step explanation:
Given:
Ethan bought 4 packages of pencils.
No of Packages = 4
No of pencils given to friend = 8 pencils
No of pencils left over =40 pencils
∴Total Number of Pencils = No of pencils given to friend + No of pencils left over =
Total Number of pencils in each package = 
Yes therefore your answer would be −2+6−4 if u simplify that it would be 0<span>

Answer:
9 + f = 16
Step-by-step explanation:
So just say 9 + f = 16 since the tree grew to 16, and the f is the amount.
