Answer:
The reason why linear pairs and vertical angles are used to prove lines are parallel is because they area transversal drawn through the parallel lines will form angles on each of the two parallel lines including;
1) Supplementary linear pairs and
2) Vertical angles
3) Alternate angles
Given that either;
a) The corresponding angles that form the linear pairs are congruent
b) The corresponding vertically opposite angles are congruent
c) The corresponding alternate angles are congruent, we have;
The two lines are said to be parallel.

Answer:
-27
Step-by-step explanation:
9(4x – 15)
Substitute 3 for x
9((4)(3) - 15)
Multiply (4)(3) = 12
9 ( 12 - 15 )
Subtract 12 - 15 = -3
9(-3)
Multiply 9(-3) = -27
Plug in two values for x, say, 0 and 1.
Lets start with solving the equation when x=0.
y=2(0)-3
y=0-3
y=-3.
So, when x=0, y=-3. Graph (0, -3)
Next, x=1
y=2(1)-3
y=2-3
y=-1
So, when x=1, y=-1. Graph (1,-1)
Draw a line between the two points, and that should be your answer! Hope this helped :)
Here is you're answer:
In order to find the answer you have to find the common denominator and then subtract.

- Find the common denominator:



Therefore you're answer is "2/15."
