Answer:
She forgot to flip the sign in the last step.
Step-by-step explanation:
In inequality, if you multiply or divide by a negative number, you would have to reverse the inequality sign.
Marice forgot to do this in the final step. She had to divide '-8' to get x completely on one side. All other steps are correct.
The correct answer is x ≥ -1.
Hope this helps.
The rest of the question is as following
=====================================
<span>Which
statement about the graph is true?
</span><span>1. The curves do not intersect.
</span><span>2. The
curves intersect at one point.
</span><span>3. The curves intersect at two points.
</span>4. The
curves appear to coincide.
==================================================
Solution:
See the attached figure
The blue graph represents the function log₆(x-1)
The red graph represents the function log₂(2x+2)
As shown from the figure
the curves does not meet.
Therefore, the correct statement is option 1
<span>1. The curves do not intersect. </span>
