Add 25 to both sides x-25 +25 =7 +25
x =32
When the squared terms are of different signs, the equation generally describes a hyperbola. This one has its vertices at x=±30, so the parameters of interest are
domain: (-∞, -30] ∪ [30, ∞)
range: (-∞, ∞)

We have:

Substitute for x and y



Step-by-step explanation:
- -9x+18<-27
- -9x+18-18<-27-18
- -9x<-45
- x>-45/-9
- x>5
I think 6 because 12=3x-6
