Complete the square
first isolate x terms
y=(x^2-4x)-9
complete square inside (take 1/2 of square of b )
-4/2=-2, (-2)^2=4
add 4-4 inside
y=(x^2-4x+4-4)-9
complete the square
y=((x-2)^2-4)-9
y=(x-2)^2-4-9
y=(x-2)^2-13
Answer:
2 is your answer
Step-by-step explanation:
If h(x)= 5 then 5= 2x +1
so 5 = 2x + 1
-1 -1 on both sides
then 2x = 4
2 2 divide by 2
which x = 2
Hope my answer has helped you!
When two people answer your question, there is a crown on both, then click the one you want to give it to.
