-0.4 because it is 3.6 - 4
Answer:
Five x squared plus two
Step-by-step explanation:
An exponent of two is always pronounced as "squared"
Answer: x = 16, x = 8
Step-by-step explanation:
|a| > 0, there are two solutions
|a| = 0, there is one solution
|a| < 0, there are no solutions
So, in this problem, we have two solutions.
In absolute value, the expression inside can be equal to itself OR its opposite.
Ex: |y| = y, |y| = -y
So, we can write two equations:
x - 12 = 4, x = 16
-x+12 = 4, x = 8
Check: |16 - 12| = |4| = 4
Check: |8 - 12| = |-4| = 4
Answer to the nearest tenth is 20.8
No because (0,1) isn't a solution for both equations. It is for the first one, but not the second.
