Answer:
B.
Step-by-step explanation:
First, the equation must be solved, so x + 6 ≤ -9
Step 1: Subtract 6 from both sides to cancel the +6; The new equation is
x ≤ -15.
This means that the inequality must have a filled in circle starting at -15, and an arrow going to the left because -15 is greater.
For proof, substitute -20 for x:
-20 ≤ -15 ←This is true
Answer:
x = 29
Step-by-step explanation:
If the lines are parallel
< CBA = < DAB due to the fact that they are alternate interior angles
42 = DAB
We also know that
DAB + BAC + CAE = 180 since they form a straight line
Substituting the given values
42+ 109 + x = 180
Combine like terms
151 + x = 180
151+x-151 = 180-151
x = 29
