Answer:
<em>The values are a=6, b=8</em>
Step-by-step explanation:
<u>System of Equations</u>
We are given the system of equations:
ax - by = 4
bx - ay = 10
And it's known the solutions are: x=2, y=1.
Plugging in the solutions:
2a - b = 4 [1]
2b - a = 10 [2]
Now we have to solve the system above. Multiply [1] by 2:
4a - 2b = 8
Now we add with [2]:
3a = 18
a = 18/3 = 6
a = 6
From [2]:
2b - 6 = 10
2b = 16
b = 16/2 = 8
b = 8
The values are a=6, b=8

Answer:
x=6
Step-by-step explanation:
Given the x-intercepts of a parabola: 
The equation of symmetry at the parabola's vertex is x=h
Where 
In this case,

Therefore, the line of symmetry of the parabola is x=6 and is also the x-coordinate of the parabola's vertex.
Answer:
5.5
Step-by-step explanation:
2 times 3 is 6 then but to the other side so plus 6 then You have 2y=11
then you dived it by two so 11 dived by 2 and you get 5.5
