Answer:
(0,0) and (3,0)
Step-by-step explanation:
When you graph y= -2x^2+6x it turns out to be a parabola. So, that means that this parabola actually crosses two points on the x-axis; (0,0) and (3,0)

Answer:
(i)unique solution
Explanation:
We solve for x1 thus in the first equation:
x1-3x3=-3
x1-9=-3
x1=-3+9
x1= 6
We solve for a thus in the second equation:
2x1+ax2-x3=-2
2+a2-x3=-2
a2-x3=-4
a2=-4+x3
If you reduce the 5 for 20, you will get 1 for $4. Therefore, 12×4 will be the answer ($48)
