Answer:
x >=5 or x <=-3
Step-by-step explanation:
Solve an absolute value inequality
3|x-1| >= 12
Divide each side by 3
3/3|x-1| >= 12/3
|x-1| >= 4
Now there are two solutions
x-1 >= 4 or x-1 <= -4
Add 1 to each side
x-1+1 >= 4+1 or x-1+1 <= -4+1
x >=5 or x <=-3
Correct option is A) [-13/4, 9/4] .
<u>Step-by-step explanation:</u>
Here we have following equation as |2 + 4x| = 11 or , . We need to solve for the value of x .Let's find out:
We know that Modulus Function is both positive & negative for particular values of x , i.e.
|2 + 4x| is positive :
⇒
⇒
⇒
⇒
|2 + 4x| is negative :
⇒
⇒
⇒
⇒
Therefore , Correct option is A) [-13/4, 9/4] .
The answer is A. 14h + 11d
because if you 3d and 8d it will give you 11d
the take 24h and subtract to 10h it will give you 14h
so when you write it you answer is 14h + 11d
Hope this helps! :)
