See attachment for graph
Step-by-step explanation:
Given
![x + 2y = 7](https://tex.z-dn.net/?f=x%20%2B%202y%20%3D%207)
Required
Draw the graph
First, we identify at least 2 possible values of x and y
Let ![x = 1](https://tex.z-dn.net/?f=x%20%3D%201)
Solve for y
![x + 2y = 7](https://tex.z-dn.net/?f=x%20%2B%202y%20%3D%207)
![1 + 2y = 7](https://tex.z-dn.net/?f=1%20%2B%202y%20%3D%207)
![2y = 6](https://tex.z-dn.net/?f=2y%20%3D%206)
![y = 3](https://tex.z-dn.net/?f=y%20%3D%203)
So, a point is: ![(1,3)](https://tex.z-dn.net/?f=%281%2C3%29)
Let ![x = 3](https://tex.z-dn.net/?f=x%20%3D%203)
Solve for y
![x + 2y = 7](https://tex.z-dn.net/?f=x%20%2B%202y%20%3D%207)
![3 + 2y = 7](https://tex.z-dn.net/?f=3%20%2B%202y%20%3D%207)
![2y = 7 -3](https://tex.z-dn.net/?f=2y%20%3D%207%20-3)
![2y = 4](https://tex.z-dn.net/?f=2y%20%3D%204)
![y = 2](https://tex.z-dn.net/?f=y%20%3D%202)
So, another point is: ![(3,2)](https://tex.z-dn.net/?f=%283%2C2%29)

Using equation of motion.
S = ut + (1/2)gt²
Where S = Height, t = time, g = acceleration due to gravity = 9.8 m/s²
time, t = 8 seconds
Since it was dropped from height, initial velocity, u = 0
S = 0*t + (1/2)gt²
S = (1/2)gt²
S = (1/2)*9.8*8² = 4.9 * 8 * 8 = 313.6
Therefore the ledge is 313.6 m tall.
The student will have $135 in her bank account at the end of the ninth week. You can fine this out by finding out the amount she deposits a week and to do this you would take the $30 and divide it by 2 because she had $30 at the end of the second week.
30/2=15
So you see that the student deposits $15 each week, so to find out how much money she will have in 9 weeks you will multiply her $15 by 9.
15x9=135
So the student will have $135 at the end of the ninth week.
Answer:
9/20
Step-by-step explanation:
First, turn the fractions into decimals then divide them and you get .45.
Find .45 in a fraction and it's 9/20. That's its simplest form.
