Answer:
Using Transformations
Step-by-step explanation:
Hey there! I'm happy to help!
To find the x value of the midpoint, you add the 2 x values and divide by 2.
-8+6=-2
-2/2=-1
For the y value, you do the same thing but with the y values.
7-9=-2
-2/2=-1
Therefore, our midpoint is (-1,-1).
Have a wonderful day! :D
Answer:

Step-by-step explanation:
Represent the sofa with S and the love seat with L.
So, we have:
--- Total Cost

Required
Determine the value of L
Substitute 2L for S in the first equation.


Divide both sides by 3



<em>Hence, a love seat costs 117.0</em>
<em></em>
<u>Using Graph</u>
See attachment for graph
S is plotted on the y-axis and L is on the x-axis.
The green line represents
while the orange line represents 
When the line of the graph is traced to the x-axis, we have:
