I'm pretty sure the answer would be B, but not entirely sure. I'm rusty on my linear inequalities. It would make sense because if you divide -21 by -7, the sign would flip and make a positive 3 which is the Y intercept.

8. Solve the system of equations using substitution.
Elodia [21]

Answer:

D

Step-by-step explanation:

In order to solve this we need to plug in the answer choices and make sure they work for BOTH answers!

Let us start with option A. (6,3)  3 = 4(6) + 6     = 3 = 30 This is automaticly wrong because 3 doesnt equal 30. There is no need to try it on the second equation since the first one was wrong.

Next answer choice, B  (3,6)  6 = 2(3) =   6=6. The second equation works perfect for this. Now we have to make sure that it works for the first one as well. 6 = 4(3) + 6   = 6 = 18 which is wrong.

Next, C.  (1,2)   2 = 2(1) = 2=2 Right now lets check the other equation.

2 = 4(1) + 6 = 2=10. Wrong

Last, D. (-3, -6)    -6 = 2(-3)  = -6 = -6 Right now lets check the other equation.

-6 = 4(-3) + 6 = -6 = -6. CORRECT. Answer choice D works for both equations.

Sorry for the wait of response.

Answer : 110 degree

To find angle 1 , we apply outside angle theorem  Lets name each point  Measurement of arc EF=280 degrees  

Measurement of arc GH = 60

Angle D = angle 1

Please refer to the theorem attached below  

angle D = \frac{arc(EF)-arc(GH)}{2}

Now we plug in the values

angle 1 = \frac{280-60}{2}

angle 1 = 110

Measurement of angle 1 = 110 degrees
