Answer:
Step-by-step explanation:
The last one -- D -- is the closest correct answer. None of them, however, is right.
y = -1/4 x + 8 Let x = - 8
y = -1/4 * - 8 + 8 The standard rule is starting from the left, do the multiplication first then do the addition
- 1/4 * - 8 will first of all give you a positive result. When 2 minuses are multiplied they give a positive answer.
-1/4 * - 8 = 1/4 * 8
1/4 * 8 = 2
y = 2 + 8
y = 10
So the ordered pair (-8 , 10) is the answer.

Answer: x=65
Since they're vertical angles both sides are equal to 145 degrees
So, 145-15= 130 to get rid of the constant
Then, 130/2=65
To check you work add up all of your solutions to get 145
2*65=130 & 130+15=145
Therefore, x=65
