Answer:
D. 16
Step-by-step explanation:
1. Because these are vertical angles (opposite pair of angles that are formed by intersecting lines), these are congruent. That means (8x-8) = (7x+8).
2. (Solving)
Step 1: Subtract 7x from both sides.
Step 2: Add 8 to both sides.
Step 3: Check if solution is correct.
Therefore, the answer is D. 16.
Answer:
Step-by-step explanation:
Given
Set: -10 to 10
Required
Write as interval notation
We start by writing the given parameter as an inequality
The direct representation of and
in interval representation of sets is
and
, which shows that the beginning and end of the interval are inclusive;
So, the above inequality in interval notation is:
