X is -2 I think if you’re solving for x if not 3^4 is 81
I think it’s either 8 or negative 8
Given:
is the transversal that intersects the lines r and s.
Required:
Pairs of alternate exterior angles.
Explanation:
Line q intersects the lines r and s.
The alternate exterior angles are,

Answer:
Thus the required answer is option 2.
Answer:
5x^2-12x-2
Step-by-step explanation:
Use distributive property, then add like terms. See file below for steps.
Answer:
Step-by-step explanation:
Use substitution, y=3x+18 so -12x+4(3x+18)=-24. From here you can try to solve for x
-12x+12x+72=-24
The xs cancel, which leaves you with 72=-24
Since 72 cannot equal -24 there is no answer to this system of equations
