I need help on this one please
saw5 [17]

Answer:

B

Step-by-step explanation:

When looking at the number line, we can see the distance between A and B is one unit

A |-2| + |-1| = 2+1 =3    That is not 1 unit

B 2-1  =1  that is  1 unit

C  -2 + -1 = -3  that is not 1 unit

D  |-1| - (-2) = 1 + 2 =3  that is not 1 unit

Even though it says all expressions,  there is only 1 that shows a distance of 1 unit

Please help me solve this 200(20)^x>500x+400
s2008m [1.1K]
Hi there!

200(20)^x > 500x + 400

Let's find the critical points of the inequality

200(20^x) = 500x + 400

Now we can divide both sides by 200

(200(20^x))/200 = (500x + 400)/200

20x^x = 5/2 x + 2

There are no critical points.

Thus,

The answer is: No solution

As always, it is my pleasure to help students like you.
