3.2 -9x+ 7.1 -3x
= (-9x -3x)+ (3.2+ 7.1) (combine like terms)
= -12x+ 10.3
The final answer is -12x+ 10.3~

Answer:
x=3
Step-by-step explanation:
You have to look at the line(axis of symmetry) and determine what number it is it going thought, and whether it is going through the x or y axis.
In this case the axis of symmetry is going through the x axis and 3, therefore the answer is x=3.
Hope this helps!
5x + 10y = 18
x = y -6, we substitute this into first equation.
5x + 10y = 18
5*(y - 6) + 10y = 18
5y - 30 + 10y = 18
So it the last option from the top.
