Explain why a change from 20 to 40 is a 100% increase, but a change from 40 to 20 is a 50% decrease. Increasing 20 to 40 is the

STALIN [3.7K]

Answer:

To find increase/decrease, divide the starting number by the ending number.

20 ÷ 40 = 0.5

0.5 can be represented by 50%.

40 ÷ 20 = 2

2 can be represented by 200%. This is why decreasing 40 to 20 is a 200% increase. In the wording, it says it's a 100% increase. That would be 20 plus 20 times 1 (which is the same as 100%) which is 40.

The midpoint of AB is M(-2, -1). If the coordinates of A are (-7, 2), what are the coordinates of B?

slega [8]

Answer:

Coordinates of B is (3,-4)

Step-by-step explanation: $\frac{-7+x^{2} }{2}=-2$

$\frac{2+y^{2} }{2} =-1$

You multiply -2 by 2 to get -4 and then create the equation $-7+x^{2} = -4$ then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)
