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.

3/5n - 4/5 = 1/5n....multiply everything by 5 to get rid of the fractions
3n - 4 = n
-4 = n - 3n
