Answer:
e = 250 + 15m
Step-by-step explanation:
The earnings or "e" are determined by the solution of the $250 he's earned from the start and the $15 he earns are dependent on the amount of mattresses he's sold so "m" has to be multiplied by the 15.
Answer:
![y=8](https://tex.z-dn.net/?f=y%3D8)
![RS=77, ST=31](https://tex.z-dn.net/?f=RS%3D77%2C%20ST%3D31)
Step-by-step explanation:
Note that the entire segment RT is the combined lengths of RS and ST. So:
![RT=RS+ST](https://tex.z-dn.net/?f=RT%3DRS%2BST)
We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:
![108=(9y+5)+(3y+7)](https://tex.z-dn.net/?f=108%3D%289y%2B5%29%2B%283y%2B7%29)
On the right, combine like terms:
![108=(9y+3y)+(5+7)](https://tex.z-dn.net/?f=108%3D%289y%2B3y%29%2B%285%2B7%29)
Add:
![108=12y+12](https://tex.z-dn.net/?f=108%3D12y%2B12)
Subtract 12 from both sides. The right cancels:
![96=12y](https://tex.z-dn.net/?f=96%3D12y)
Divide both sides by 12:
![y=8](https://tex.z-dn.net/?f=y%3D8)
So, the value of y is 8.
To find RS and ST, substitute 8 for y. So:
![RS=9y+5](https://tex.z-dn.net/?f=RS%3D9y%2B5)
Substitute 8 for y:
![RS=9(8)+5](https://tex.z-dn.net/?f=RS%3D9%288%29%2B5)
Multiply:
![RS=72+5](https://tex.z-dn.net/?f=RS%3D72%2B5)
Add:
![RS=77](https://tex.z-dn.net/?f=RS%3D77)
Do the same for ST:
![ST=3y+7](https://tex.z-dn.net/?f=ST%3D3y%2B7)
Substitute 8 for y:
![ST=3(8)+7](https://tex.z-dn.net/?f=ST%3D3%288%29%2B7)
Multiply:
![ST=24+7](https://tex.z-dn.net/?f=ST%3D24%2B7)
Add:
![ST=31](https://tex.z-dn.net/?f=ST%3D31)
Graphs like these (lines) come in the form y = mx + b where m is the slope and b is the y intercept. Y intercept is where the graph intersects the y axis so the value would be 5
