Answer:
y=10/4-7
Step-by-step explanation:
Answer:
See attachment
Step-by-step explanation:
We want to graph the system
2x+y=8
-x+2y=6
Let us rewrite the lines in slope intercept form:
y=-2x+8

The first line has a slope of -2 and a y-intercept of 8
The second line has a slope of 1/2 and a y-intercept of 3
We can no graph the lines as shown in the attachment.
To find the slide we can us the pythagorical theorem that say:
![h=\sqrt[]{l^2_1+l^2_2}](https://tex.z-dn.net/?f=h%3D%5Csqrt%5B%5D%7Bl%5E2_1%2Bl%5E2_2%7D)
Where l1 and l2 iare the leg of the triangle so in our problem will be:
![\begin{gathered} h=\sqrt[]{28^2+21^2} \\ h=\sqrt[]{784+441} \\ h=\sqrt[]{1225} \\ h=35 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20h%3D%5Csqrt%5B%5D%7B28%5E2%2B21%5E2%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B784%2B441%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B1225%7D%20%5C%5C%20h%3D35%20%5Cend%7Bgathered%7D)
So the slide is 35 ft
B, no
Subtract 2c from both sides to get
-c=-4
Multiply by -1 to get
c=4
