I'm attaching the solution.. feel free to ask if you have questions.. I basically did long division. Hope this helps.
Answer:
When two quantities increase or decrease together they are said to be directly. proportional
1/9
Here's the proper explanation:
Since the vertex is (2,-1), the original equation will look like this: y=a*(x-2)^2-1
When the substitution happens we get to this:
0=a*(5-2)^2-1 then 1=a*(5-2)^2 -> 1=a*9
So, a=1/9! Written in another form:
1/9x^2-4/9x+4/9-1
Hope could help :)
The answer is 117/8 and that is simplified decimal form is. 14.625
First the left fraction 3 x 8=24+3=27 so it is 27/8
Then the right 4 x 3=12+1=13
27 x 13=351
8 x 3=24
351/24
