The first thing we must do in this case is to solve both inequations.
We have then:
Inequality 1:
6 -2x <12
6-12 <2x
-6 <2x
-6/2 <x
-3 <x
Inequality 2:
7 + 2x <-11
2x <-11-7
2x <-18
x <-18/2
x <-9
Answer:
(-inf, -9) U (-3, inf)
There are millions of solutions I’d recommend going to desmos and putting in a polynomial to find out if it does
Answer:
The margin of error is multiplied the square root of 2 (I got it right on my test)
N3Y+7 can have infinate solutions
