G(x)=-2x-4
f(x)=15+0.75x
the common solution Q is their intersection-> calculate x by setting them equal:
-2x-4=15+0.75x
-2x-(3/4)x=19
-(11/4)x=19
x=-4*19/11
x=-76/11
calculate y:
f(-76/11)=15+(3/4)*(-76/11)
=15+(-3*19/11)
=15+(-57/11)
=15+-5-(2/11)
=10-(2/11)
=108/11
so the solution is a) (-76/11, 108/11)

Answer:
Step-by-step explanation:
Draw a horiz. line. Locate x = -7 on this line. It will be 7 units to the left of the origin. Now draw a vertical, dashed line thru x = -7. Shade the area to the right of this dashed line. The shaded area represents the solution set of x > -7.
