Answer:
16
Step-by-step explanation:
Distance formula = 
Depending on which point is A and Which point is B, the answer is one of the two.
However, there is no such thing as negative distance, so your answer is 16 points in a certain direction.
Answer:
p = 2a-22
a= p-20
these will help you find the actual value
Step-by-step explanation:
this is not for the actual value
pierre = p
alex = a
p = a+20
p-20 = a
p+22 = 2a
p = 2a-22
2(2ax-y)=3ax-4y
4ax-2y=3ax-4y
Move 3ax from the right to the left. You do so by subtracting 3ax from both sides. Once doing so, you should have:
ax-2y=-4y
Isolate ax. You do so by adding (-2y) to both sides. After doing so, you should have:
ax=-2y
To isolate y by itself, you divide everything by -2, thus, equaling y= ax/-2

Answer:
Step-by-step explanation:
The third line of the solution is incorrect. It should be ...
5x +2 = -5x +2
Then the one solution can be found:
10x = 0 . . . . . . . . . add 5x-2 to both sides
x = 0
Answer:
x = 8 and y = 21
Step-by-step explanation:
Alternate interior angles are equal. Therefore, 7x + 12 = 12x - 28
12 = 5x - 28
5x = 40
x = 8
Now, supplementary angles have a sum of 180. Therefore, 12x - 28 + 9y - 77 = 180
Substitute 8 in for x and 12(8) + 12 + 9y - 77 = 180
96 - 28 - 77 + 9y = 180
9y - 9 = 180
9y = 189
y = 21
