Answer:

  D. -31m^4n-8m^2

Step-by-step explanation:

Eliminate parentheses by distributing the minus sign. Then collect terms:

  (9mn-19m^4n)-(8m^2+12m^4n+9mn) = 9mn -19m^4n -8m^2 -12m^4n -9mn

  = m^4n(-19 -12) +mn(9 -9) +m^2(-8)

  = -31m^4n -8m^2 . . . . . matches choice D

Answer:

By the end of this resource, you will be able to identify domain and range from any given contextual situation.  

Determining the domain and range from a linear or quadratic contextual situation is similar to determining the independent and dependent variables.

Step-by-step explanation:

Suppose you are interviewing for a job. Your employer offers you the choice of two different options for your pay. The first option is to pay you $10.00 per hour and give you a raise of $.50 per hour at the end of the year. The second option is to pay you $11.50 per hour and give you a raise of $.25 per hour at the end of the year.

First, find a function for each option. To do that, you have to know what the domain and range might be. Let y = the amount you will make at the end of the year and x = the number of hours you work. Thinking about what would be reasonable values for x and y will help determine the domain and range.

First, let's think about the domain. Since x represents the numbers of hours you worked for the year, would it be reasonable to have negative values? If you said NO, you would be correct. We can assume the lowest possible value in the domain would equal zero. So, our domain would be {x| x ≥ 0}.

Now, let’s think about the range. Since y represents your earnings at the end of the year, would it be reasonable to have negative values? If you said NO again, you would be correct. You cannot earn a negative amount. We can assume the lowest possible value in the range would also equal zero. So, our range would be {y | y ≥ 0}. You should be able to relate with this situation since you may have to make a decision in comparing two or more job offers in your future.

It's important to realize that every situation is different and you must think about what is reasonable.

Answer:

a. y = -2x-5

Step-by-step explanation:

*Don't get confused the y-axis scale is 2

I guess you would kind of have to guess by looking at the graph for this one, the y-intercept is 5.

The graph is negative because it is pointing the opposite way

The slope is 2 because the y-axis has a scale of 2

With these facts you can formulate that the equation would be y = -2x-5

Answer:

100

Step-by-step explanation:

Since, line a is parallel to line t ( from diagram ).

x - 30 and 70 are alternate interior angles.

Reason : -

Alternate interior angles are equal when two lines are parallel and cut by a transversal line.

x - 30 = 70

x = 70 + 30

x = 100

Table:

1st row: x = -2 and y = 1

2nd row: x = -1 and y = 2

3rd row: x = 0 and y = 3

(It will continue going on with x and y each going up by one infinitely.)

Graph:

The graph is linked, so you can plot the points.

If needed, here are the plotted points:

-2, 1

-1, 2

0, 3

(The same things put in the table. Also, if needed, I added the extra points of 1, 4 and 2, 5 on the image.)

Hope this helps! :D

Answer:

its B

Step-by-step explanation:

X:2

Y:4

Z:6

The values that best complete the chart as per the concept of ratio are X:2, Y:4, and Z:6.

To determine the correct values for the chart, let's analyze the given information about an object moving at a constant acceleration:

The first column represents time in seconds (0, 1, 2, 3).

The second column represents velocity in meters per second (0, X, Y, Z).

Since the object is moving at a constant acceleration, its velocity is changing by the same amount in equal time intervals.

We can use the formula for constant acceleration:

Velocity (V) = Initial Velocity (U) + (Acceleration × Time)

Given that the object starts from rest (initial velocity, U = 0), we can deduce the following:

At time 1 second (T = 1), the object's velocity is X m/s.

At time 2 seconds (T = 2), the object's velocity is Y m/s.

At time 3 seconds (T = 3), the object's velocity is Z m/s.

Based on this information, the correct values for the chart are:

X: 2 (Velocity at 1 second is 2 m/s)

Y: 4 (Velocity at 2 seconds is 4 m/s)

Z: 6 (Velocity at 3 seconds is 6 m/s)

Answer:

221.6667

Step-by-step explanation:

Step one is to add all of the players weight together.

- lets write an equation 3(201)+ 6(232)

Now simplify the expression, 603+1392. Add them together to get  1995 LBS

Step two is finding the mean

- The mean is adding up all the numbers and dividing by the amount. So there are 9 players and their total weight is 1995 LBS. take 1995 and divide by 9 to get your answer. This is 221.66667. Make sure to round if the question asks!!!!

24,500 and collected Accounts Receivable of $ 28,500. The balance in Accounts Receivable at June 30, 2022 will be: $14,900

Using this formula

2022 Balance in Accounts Receivable=Accounts Receivable balance as on June 1, 2022+ Credit sales  -Collected Accounts Receivable

Let plug in the formula

2022 Balance in Accounts Receivable=$18,900+$24,500-$28,500

2022 Balance in Accounts Receivable=$14,900

Answer:

[tex]\frac{1}{x^{12} }[/tex]

Step-by-step explanation:

Given [tex](\frac{x}{x^{-5}})^{-2}[/tex]

The Negative Exponent Rule states that, [tex]a^{-n} = \frac{1}{a^{n}}[/tex]

Basically, since you're raising the fraction inside the parenthesis to a negative exponent, the whole fraction becomes a denominator of 1:  [tex]\frac{1}{(\frac{x}{x^{-5}})^{2}}[/tex]

Then, you'll have to work on the denominator:

[tex]\frac{1}{(\frac{x}{x^{-5}})^{2}} = \frac{1}{\frac{x^{2} }{(x^{-5})^{2}}}[/tex]  

Next, you'll have to work on the divisor of x² (in the denominator), [tex](x^{-5})^{2}[/tex] by using the Power-to-Power Rule of Exponents: [tex](a^{m})^{n} = a^{mn}[/tex], which results in:

[tex](x^{-5})^{2} = x^{-10}[/tex]

Since it is a negative exponent, you'll have to apply the Negative Exponent Rule once again to the denominator.

[tex]\frac{1}{(\frac{x}{x^{-5}})^{2}} = \frac{1}{\frac{x^{2} }{(x^{-5})^{2}}} = \frac{1}{\frac{x^{2} }{x^{-10}}} = \frac{1}{\frac{x^{2} }{\frac{1}{x^{10}}}}[/tex]    

At this point, you could apply the Fraction rule onto the denominator: [tex]\frac{a}{\frac{b}{c}} = \frac{a*c}{b}[/tex]

So the denominator now becomes:

[tex]\frac{1}{\frac{x^{2} }{\frac{1}{x^{10}}}} = \frac{1}{x^{2}*x^{10} }[/tex]

Finally, you could apply the Product Rule of Exponents, [tex]a^{m}a^{n} = a^{m + n }[/tex] onto the denominator:

   [tex]\frac{1}{x^{2}*x^{10} } = \frac{1}{x^{2+10}} = \frac{1}{x^{12} }[/tex]

Therefore, the correct answer is: [tex]\frac{1}{x^{12} }[/tex]
