This is an equation of a parabola that opens upwards.

Answer:
The x-coordinate of the solution to this system of equations is 3
Step-by-step explanation:
Given the system of equations:
....[1]
....[2]
Add equation [1] and [2] we have;

Simplify:

Divide both sides by 3 we have;
x = 3
Substitute in [1] we have;
3+y = 3
⇒y = 0
Solution for the given system of equation is= (3, 0)
Therefore, the x-coordinate of the solution to this system of equations is 3
Answer:
660.08
Step-by-step explanation:
1. first you will need to line up the decimals and make sure the places are correct
647.2
+ 12.88
2. Then you just add them
