Let's actually find the sol'n set.
<span>Line A: 2x + 2y = 8
Line B: x + y = 4
becomes
</span><span> 2x + 2y = 8
x + y = 4
------------------ Multiply the 2nd equation by -2, obtaining -2x - 2y = -8,
and then add your result to the first equation:
</span> 2x + 2y = 8
-2x - 2y = -8
------------------- Combine all 3 columns.
0 + 0 = 0
0 always = 0, so there are infinitely many solutions to this system.

Answer:
Step-by-step explanation:
2x-3y=6
-3y = -2x + 6
y = -2x/-3 + 6/ -3
y = 2x/3 - 2 {y =mx + c}
slope = 2/3
The required line's slope is also 2/3 as it is parallel to this line
Point(9, -3)
y -y1 = m(x-x1)
y - (-3) = 2/3 (x - 9)
y + 3 = 2x/3 - 2*9/3
y + 3 =2x/3 - 2*3
y + 3 = 2x/3 -6
y = 2x/3 - 6 - 3
y = 2x/3 - 9
Answer: 111.72 m^2 if they want round its 112
Is from O to C 14m
A=pixr^2
3.14x14^2= 615.44 m/2 half circle = 307.72
Area of triangle A= 1/2bh. .5x28x14=196
307.72-98=196= 111.72 m^2
