Solve \(\frac{-72}{x} = 9\) using the distributive property.
Answers
Step by Step:
1) -72/x = 9 first, you multiply both sides by x and get -72= 9 * x
2) -72= 9 * x second, you divide both sides by 9 to isolate x by itself -72/9 = 9 * x/ 9 (the 9 cancels on the right side of the equation leaving x by itself)
Leaving you answer to be x = -8
Answer:
The answer is
→ \(x=-8\)
Step-by-step explanation:
Given: \(\frac{-72}{x} = 9\)
Solve:\(\frac{-72}{x} = 9\)
Step 1: Multiply all terms by the same value to eliminate fraction denominators.
\(\frac{-72}{x} = 9\)
⇒ \(x * \frac{-72}{x} = x * 9\)
Step 2: Cancel multiplied terms that are in the denominator.
\(x * \frac{-72}{x} = x * 9\)
⇒ \(-72 = x * 9\)
Step 3: Re-order terms so constants are on the left.
\(-72 = x * 9\)
⇒ \(-72 = 9x\)
Step 4: Divide both sides by the same factor.
\(-72 = 9x\)
⇒ \(\frac{-72}{9} = \frac{9x}{9}\)
Step 5: Simplify.
Divide the numbers.\(\frac{-72}{9} = \frac{9x}{9}\)
⇒ \(-8 = \frac{9x}{9}\)
Cancel terms that are in both the numerator and denominator.\(-8 = \frac{9x}{9}\)
⇒ \(-8 = x\)
Move the variable to the left.\(-8x = x\)
⇒ \(x = -8\)
Hence, \(x = -8\) is your answer.

Answers
Answer:
$19.00
Step-by-step explanation:
The answer would obviously not be the first 2 due to those being lower than the sale price so it would have tot be one of the bottom 2 so i chose one of the two and figured out what 20% off those prices would be to see which matched with $15.20 :) pls give me brainliest
Answer:
C
Step-by-step explanation:
Because 20% of 15.20 is 3.04.
Then, 3.04+15.20= C) $18.24

\(\textsf{(e)} \quad 9x^2-72x+144\)
(f) Not equivalent.

Equivalent expressions are expressions that simplify to the same expression.

Part (c)
The expressions are not equivalent.
The coefficients of the x-variables are the negatives of one another, and the constants are different numbers.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)

The median is the middle value in the data set. Since there are five values in the data set, the middle value is the third value, which is 35. Therefore, the median of the data set is 35.
To find the mean, we need to add up all the values in the data set and divide by the total number of values:
(3 + 31 + 35 + 36 + 38) / 5 = 28.6
Therefore, the mean of the data set is 28.6.
the median is always the middle number so the median is 35. hope this helps you to remember in the future

How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answers
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)
