value of x is 
and value of y is 
Step-by-step explanation:
We need to find Which expression could be substituted for y in the second equation to find the value of x
The given equations are:
For putting value of y in second equation, we will find from equation 1
From equation 1:
Putting value of y i.e y=10+2x in equation (2) to find value of x
So, now finding value of y by putting value of x= -29/4 in eq(1)
So, value of x is and value of y is

Answer:
1) (-3,-2)
2) x=-3
Step-by-step explanation:
1) The vertex of a parabola is the turning point that is the minimum or maximum of the graph, based on the shape of the parabola. In this case, the vertex is the minimum. By looking at the coordinate points, we can tell that the minimum value where the graph changes the direction is at (-3,-2).
2) The line of symmetry is the line on the graph that cuts the shape exactly in half. This means that if you were to fold the graph along this line, the two sides would be identical. All parabolas have a line of symmetry and it always matches the vertex. The equation for the line of symmetry will be x= whatever the x-value of the vertex is. So, for this graph, the line of symmetry is x=-3.
Answer:
8a(5a - 4)
Step-by-step explanation:
To factor this expression, see what numbers and variables these two terms have in common. I can see that they both have the variable a, so a can be factored out.
40 and -32 also have 8 in common, because they are both cleanly divisible by 8.
Now we can factor 8a out of 40a^2 - 32a. Think of how many times 8a goes into 40a^2 and -32a.
8a(5a - 4)
