Explanation:
If y varies inversely as x, the two variables can be represented in an equation in the form
y
=
k
x
where
k
is some constant.
We are given that
y
=
5
when
x
=
6
. We can plug this into the above equation to find what
k
is:
5
=
k
6
30
=
k
Based on this we can create our equation:
y
=
30
x
And then find
x
when
y
=
2
:
2
=
30
x
2
x
=
30
x
=

Answer: I HELP YOU......... I dunno the answer oops guess i won't help oh well to bad so sad.. jk WUT UP CHICA DE CASA?
Step-by-step explanation:
The third one is a point with the first equation.
I had to simplify the second equation.
It simplified to,
The second one with the above is didn't go through so I'd say no solution.

Answer: (y-2)(y-7)</h3>
=====================================================
Explanation:
To factor this, we need to find two numbers that
- A) multiply to 14 (last term)
- B) add to -9 (middle coefficient)
Through trial and error, you would find that the two numbers are -2 and -7
-2*(-7) = 14
-2 + (-7) = -9
So that's why the given trinomial factors to (y-2)(y-7)
You can use the FOIL rule to go from (y-2)(y-7) back to y^2-9y+14 again.
