By definition of absolute value we have two equalities:
2x + 1 = 10
2x + 1 = -10
For 2x + 1 = 10:
2x + 1 = 10
2x = 10-1
2x = 9
x = 9/2
For 2x + 1 = -10:
2x + 1 = -10
2x = -10-1
2x = -11
x = -11 / 2
Answer:
{-11/2, 9/2}
0 means u do not move right or left at all and the 4 means u move up 4 units.
Answer:

Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the measure of the third angle of the triangle on the bottom
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
Let
x ----> the measure of the third angle


step 2
Find the measure of angle m
we know that
----> by vertical angles
therefore

1. 6
2.8
3.3
hope this wasn’t late
The answer is D
Make it into improper fraction
Then flip 2/5 to 5/2 reciprocal
Multiply
