It would be 3,000 as it is the next thousand. Since 2,641 is over 2,500 you can round to the next thousand 3,000
-|-3p|
-|-3(5)|
= -|-15|
= -(15)
= -15
The value of the expression when p = 5 is -15.
2x - 1 + 3x = 0
2x + 3x - 1 = 0
(2 + 3)x - 1 = 0
5x - 1 = 0
Just reflect C and D across the y-axis
C is (-4, -4) so A is (-4, 4)
D is (4, -4) so B is (4, 4)
