6x=78
x=13
Answer:
D)The equation is f(x)=3x^2−9x+3, and the parabola opens upward.
Answer:
(6,2)
Step-by-step explanation:
When solving a system of simultaneous equations, we want to see where the graphs intersect.
2x+5y =22 is the red line
x+y = 8 is the green line
They intersect at a point
The point is x=6 y=2
