Answer:

b) x = 7

Step-by-step explanation:

16+5x = x+12

Subtract 16 from both sides

5x = x+28

subtract x from both sides

4x = 28

divide 4 from both sides

x = 7

Hope this helps :)

Answer:

Step-by-step explanation:

I substituted the x value with the different options. I kept doing that until the equation made sense.

<h2>Hello!</h2>

The answer is: $g(x)=-\sqrt[3]{x-1}$

Let's check the roots and the shown point in the graphic (2,-1)

First,

$0=-\sqrt[3]{x-1}\\\\0^{3}=(-\sqrt[3]{x-1})^{3}\\\\0=-(x-1)\\\\x=1$

then,

$g(0)=-\sqrt[3]{0-1}\\g(0)=-(-1)\\g(0)=1\\y=1$

So, we know that the function intercepts the axis at (1,0) and (0,1), meaning that the function match with the last given option

( $g(x)=-\sqrt[3]{x-1}$ )

Second,

Evaluating the function at (2,-1)

$y=-\sqrt[3]{x-1}\\-1=-\sqrt[3]{2-1}\\-1=-\sqrt[3]{1}\\-1=-(1)\\-1=-1$

-1=-1

It means that the function passes through the given point.

Hence,

The equation which represents g(x) is $g(x)=-\sqrt[3]{x-1}$

Have a nice day!

Write an inequality for the graph. Then, in words, describe all the values of that make the inequality true.

-3 > x

The values that make this inequality true are those that are less than -3. The inequality does not include -3.
