If 3^2x+1 = 3^x+5 what is the value of X
cupoosta [38]

Answer:

4

Step-by-step explanation:

Since the base is the same, 3, you can just get rid of it using the principles of log. What you're left with is:

2x + 1 = x + 5

Now just solve for x:

2x - x = 5 - 1

x = 4

Name a value for x that will complete the inequality that is shown. Then, explain why the value makes the inequality true.
Alex17521 [72]
<h3>Answer:    0.157</h3>

========================================================

Explanation:

Convert the fraction 9/50 to decimal form. You can use either long division or a calculator.

You should find that 9/50 = 0.18 which is the same as 0.180

So the original compound inequality is the same as saying 0.125 < x < 0.180

This tells us that x is between 0.125 and 0.180 where x is not equal to either endpoint. We simply need to pick anything in this interval. It can be anything you want (I recommend to use a number line to help pick a value). One such value is 0.157. There are infinitely many values you can select from.

The number 0.157 is between 0.125 and 0.180, ie  0.125 < 0.157 < 0.180

It's very similar to saying 157 is between 125 and 180, ie 125 < 157 < 180.
