Which graph shows the solution to the inequality -3x-7 <20?
1 answer:
Answer:
x > -9
Step-by-step explanation:
The solution to the inequality is obtained as follows:
-3x -7 < 20
-3x - 7 + 7 < 20 + 7
-3x < 27
-3x/(-3) > 27/(-3)
x > -9
Notice that when you divide by a negative number, the inequality sign changes.
In the picture attached, the graph of the solution s shown. Notice that -9 is not included in the solution.

Answer:
a. Bisector is at point M
b.
Step-by-step explanation:
Question is not well formatted:
Given
Solving (a): The segment bisector
From the given parameters above
We have AM and MB
The common point in AM and MB is M;
This indicates that the bisector is at point M
Solving (b): The value of AB
First we need to determine the value of x
Because M is the point of bisector;
