Answer:
I think the answer is 81.
Step-by-step explanation:
Vertical angles are congruent.
x + 3 = 84
- 3 = -3
--------------
x = 81
Answer: a = 3
Step-by-step explanation: when you multiply 6 by -3 you get -18 and if you add 16 you get -2
so the slope is -3 and the y-intercept is 16
so a*-3 + 16 = 7
by subtracting 16 on both sides you get
-3a = -9
and to get a by itself you divide -3 on both sides
a = -9/-3
a= 9/3
a = 3
With the information given, we can set up the following system of equations:
