Hey!
The first step to solving the rest of this problem would be to distribute the parenthesis in -( 5x - 10 ).
<em>Original Equation :</em>
-( 5x - 10 )
<em>New Equation {Changed by Distributing the Parenthesis} :</em>
- ( 5x ) - ( -10 )
Now we'll simplify the equation.
<em>Old Equation :</em>
- ( 5x ) - ( -10 )
<em>New Equation {Simplified} :</em>
-5x + 10
Okay, now that that part of the equation has been changed, we can add the simplified part to our entire equation.
<em>New Equation :</em>
5x - 9 - 5x + 10
Next we need to group like terms.
<em>Old Equation :</em>
5x - 9 - 5x + 10
<em>New Equation {Changed by Grouping Like Terms} :</em>
5x - 5x - 9 + 10
And now we add the similar elements.
<em>Old Equation :</em>
5x - 5x - 9 + 10
<em>New Equation {Changed by Grouping Like Terms} :</em>
-9 + 10
And finally we simply add the numbers.
<em>Old Equation :</em>
-9 + 10
<em>Solution {Old Equation Solved} :</em>
1
<em>So, this means that 5x - 9 - ( 5x - 10 ) is</em> 1.
Hope this helps!

Answer:
4)x=2
5) (-3,4)
Step-by-step explanation:
4) f(x)=x^2-4x+4-4+5
f(x)=(x-2)^2+1
f(x)=a(x-h)^2+k
Axis of symmetry is x=h
h is 2, so axis of symmetry is x=2
5) f(x)=x^2+6x+9-9+13
f(x)=(x+3)^2+4
f(x)=a(x-h)^2+k
Vertex is (h,k)
So, vertex is (-3,4)
Sorry, I can't answer the first 3, cause I don't understand what a-value, b-value and c-value mean.
And also is this college math, cause I'm in middle-school, and I know how to do it.
