What are the domain restrictions of the expression?

Hello from MrBillDoesMath!

  h <> 10 and h <> 2      ( <> means not equal)

Discussion :

The domain restrictions are where the denominator  is 0. In this problem that occurs when

h^2 -12h + 20 = 0.

Factoring this equation gives

(h-10) (h-2) = 0

So   the values h = 10 and h =2 are NOT in the domain of this function,

Regards, MrB

h^2 - 12h + 20 can be factored to:

(h-10)(h-2)

These cannot be zero so, h cannot be 10 or 2.

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can
