Answer:
x= 3 and x= -3
Step-by-step explanation:
x^2 -9 = 0
Factor x^2-9
(x+3)(x-3)
If x+3=0, then x= -3
If x-3=0, then x= 3
Answer: ≥ without the line on the bottom.
Step-by-step explanation:
I am assuming the expression you are talking about are
and
.
If we were to replace w with 4 and calculate, we will find the answer:


Since the first expression,
, is bigger than the second expression, the correct symbol to use is ≥ without the line on the bottom.
<u>Answer:</u>
So all the possible solutions are:
<u />
<u>Solution Steps:</u>
<em>First you need to solve the real inequality to understand how to find the rest of the possible equations. </em>
<u>Add 78 to both sides:</u>
- <u />
Cancels Out
<em>So now we know the real answer, but it ask for all possible answers. </em>
(Means anything larger than 300 when you plug it into x - 78 > 300.)
<u>Numbers that are greater than 378:</u>
1.)
(False)
2.)
(True)
3.)
(False)
4.)
(False)
5.)
(True)
6.)
(True)
7.)
(False)
8.)
(True)
