Answer:
Option C is correct.
She is not correct as she use the wrong y intercepts when graphing the equations.
Step-by-step explanation:
Given the system of equations:
.....[1]
. .....[2]
equate these two equations we get;
![\frac{2}{3}x-5=-2x+3](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx-5%3D-2x%2B3)
Add 5 to both sides we get;
![\frac{2}{3}x = -2x+8](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx%20%3D%20-2x%2B8)
Add 2x to both sides we have;
![\frac{8}{3}x = 8](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7Dx%20%3D%208)
Multiply both sides by 3 we get;
8x = 24
Divide both sides by 8 we get;
x = 3
Substitute the value of x in [2] we have;
y = -2(3)+3 = -6+3
Simplify:
y = -3
Therefore, the correct solution for this given system of equation is (3, -3)
You can see the graph of these equations below.
I think it's 6.80 hope it helped
S/4-6.8=-9.8
S/4= -9.8+6.8
S/4= -3
S=-3*4
S= -12
