Is b = 7 a solution to the inequality below? 13 > 7 + b

Answers

Answer:

No, for this to be true B would need to equal 5.

Step-by-step explanation:

We need to plug in 7 for B, which is 13 > 7 + 7. Once we follow order of operations, we see that this is 13 > 14, which is not true. In order to have less than 13, we need the smaller side to equal 12. 14-2 is 12, so we subtract 2 from 7 and get 5.

Answer:

Step-by-step explanation:

13>7+b

13>7+7

13>14 = wrong

Answers

Given parameters:

Elevation of hiking = 142ft

Descent of Jane = 325ft

Height of second hiker = 24ft below sea level

Unknown:

Jane's elevation relative to the second hiker = ?

Solution:

The sea level here is the reference plane and the elevation here is zero;

Jane 142ft 142ft above sea level

Seal level 0ft 0ft Second hiker

24ft

183ft(below sea level)

The elevation of Jane in relation to the second hiker is 183 - 24 = 159ft below the second hiker.

Answers

Answer: Horizontal asymptote at y = 2

As x approaches negative infinity, the e^x term slowly approaches 0

This means 2+e^x approaches 2+0 = 2

So that's why we have a horizontal asymptote at y = 2
