Answer: The steps are not correct in several places. The correct result is "x > 2"

Explanation:

First row: they multiply both sides by 2, but on the right hand side the multiplication should act on the entire term "(3-2x)" so 2(3-2x)=6-4x

Second row should be now: 3x-8 > 6-4x | now adding 8 to both sides:

Third row should look like this : 3x > 14 - 4x

Fourth row: we want to bring the term 4x to the left so it should be something like this:

3x > 14 - 4x | add "4x" to both sides

which results in

3x + 4x > 14 - 4x + 4x

7 x > 14 | divide both sides by 7

x > 14/7

x > 2

What is the decay factor of the exponential function represented by the table?

Nina [5.8K]

Answer:

Option 2 is correct.

Step-by-step explanation:

We have been provided a table of values of an exponential function and we are asked to find out the decay factor of the function.

Upon looking at our table we can see that every time x increases by one our y value remains one-third of the previous value.

To find out decay factor we will subtract 1/3 from 1.

$1-\frac{1}{3} =\frac{3-1}{3} =\frac{2}{3}$

Therefore, decay factor of the exponential function is $\frac{2}{3}$ and option 2 is correct choice.

Let's solve for x :

$\sqrt{x - 2} - x = - 2$

$\sqrt{x - 2} = x - 2$

$1 = \dfrac{x - 2}{ \sqrt{x - 2} }$

$1 = \sqrt{x - 2}$

$x - 2 = 1$

$x = 3$
