7 - 9w = - 29

Subtract 7 from both sides

- 9w = - 36

Divide by - 9 on both sides

w = 4

The first step for solving this expression is to move the constant to the right side of the equation and then change its sign.
-9w = -29 - 7
Calculate the difference on the right side of the equation by extracting the negative sign.
-(29 + 7)
Now add the numbers together,, add the negative sign and put it back into the original equation.
-9w = -36
Divide both sides of the equation by -9.
-9w ÷ (-9) = -36 ÷ (-9)
Remember that any expression divided by itself equals 1,, so the expression becomes the following:
w = -36 ÷ (-9)
Since dividing two negatives equals a positive,, the expression changes to:
w = 36 ÷ 9
Lastly,, divide the numbers to get your final answer.
w = 4
Let me know if you have any further questions.

1) The x-axis represents the energy ( $E$ ), in joules. The y-axis represents the amplitude ( $x$ ), in milimeters.

2) The curve depicts an monotonous decrecent rate of change.

3) The amplitude is directly proportional to the root square of the energy.

<h3>How to analyze a graph relationship between two variables</h3>

In this question we have a relationship between two variables, in which we must apply principles of functional analysis to respond three questions presented in the statement.

Now we proceed to answer the three questions below:

What is on the x-axis? The y-axis? R/ The x-axis represents the energy ( $E$ ), in joules. The y-axis represents the amplitude ( $x$ ), in milimeters.
How would you describe the rate of change of the line? R/ The curve depicts an monotonous decrecent rate of change, that is, the slope converges to zero when the energy tends to infinite.
What does this tell you about the relationship between amplitude and energy? R/ The curve show a strong similarity with a function of the form $x = A\cdot \sqrt{E}$ . Hence, the amplitude is directly proportional to the root square of the energy.
