Answer:

Therefore, the equation of the line that passes through the point (-5,5) and has a slope of -8/5 will be:

                                             [tex]y=\frac{-8}{5}x-3[/tex]  

Step-by-step explanation:

Given the point (-5, 5)

slope = m = -8/5

Using the slope intercept form:  

[tex]y=mx+b[/tex]

Plugging point (-5, 5) and slope = m = -8/5 in the slope intercept form to find the y-intercept 'b'.

[tex]5=\frac{-8}{5}\left(-5\right)+b[/tex]

[tex]\mathrm{Switch\:sides}[/tex]

[tex]\frac{-8}{5}\left(-5\right)+b=5[/tex]

[tex]8+b=5[/tex]

[tex]8+b-8=5-8[/tex]

[tex]b=-3[/tex]

so the equation of the line will be:

[tex]y=mx+b[/tex]

plugging m = -8/5 and b = -3 in slope intercept form

[tex]y=\frac{-8}{5}x-3[/tex]      

Therefore, the equation of the line that passes through the point (-5,5) and has a slope of -8/5 will be:

                                             [tex]y=\frac{-8}{5}x-3[/tex]  

To find out how much money your friend spent at the clothing store, set up a proportion using the information given. Your friend spent $20 at the clothing store.

To find out how much money your friend spent at the clothing store, we can set up a proportion using the information given. Let's let x represent the total amount your friend spent.

Since your friend paid $17 for a shirt, and that amount was 85% of the total amount spent, we can set up the equation:

17/x = 85/100

Cross multiplying, we get:

100 * 17 = 85 * x

1700 = 85x

To solve for x, we divide both sides of the equation by 85:

x = 1700 / 85 = 20

Therefore, your friend spent $20 at the clothing store.

Answer:

Step-by-step explanation:

I don't have a picture so I'll visually describe it. You start at the point (0,9) because 9 is the y intercept. Now that you have your first point, to get the next point, move up one and 2 to the right. Now, you're at the point (2,10). Continue going up one and 2 to the right until you get to the end of the graph. Then, go back to the point (0,9). This time, go the opposite way. Go one down, and two to the left. Now, you should be at the point (-2,8). Continue going down one, two left until once again, you run out of room on the graph. Then, use a ruler or freehand draw a line connecting your points. Add arrows on the ends on the line. Hope this helped!

Answer:

A=800πcm²

Step-by-step explanation:

Knowing that the area of a circular sector is:

[tex]A_{cs}=\frac{\pi\alpha r^{2}}{360}[/tex]

where α is the sweep angle and r in the radio (according to the graph),

then

A=(45° π 80²)/360° = 800πcm²

Final answer:

The area swept by the door is 10π cm and the area of the sector is 200π cm².

Explanation:

To find the area swept by the door, we can first find the length of the arc created by the door when it opens. The arc length formula is given by:

Arc length = r × θ

Where r is the radius (half the width of the door) and θ is the angle through which the door opens. In this case, the radius is 40 centimeters (half of 80 centimeters) and the angle is 45 degrees.

So, the arc length = 40 cm × (45 degrees) = 40π/4 cm = 10π cm

The swept area can be approximated by treating it as a sector of a circle with radius 40 cm and central angle 45 degrees. The area of the sector is given by:

Area = (θ/360) × π × r²

Where θ is the central angle and r is the radius. Substituting the values, we get:

Area = (45/360) × π × (40 cm)² = 1/8 × π × 1600 cm² = 200π cm²

Step-by-step explanation:

The price of one share of Webb Company stock increased by $0.154 from Monday to Friday.

To calculate the change in the price of a share of stock from Monday to Friday, we subtract the price of the stock on Monday from the price of the stock on Friday. In this case, the price on Monday was $24.85 and the price on Friday was $25.004.

Change in stock price = Price on Friday - Price on Monday

Change in stock price = $25.004 - $24.85

Change in stock price = $0.154

Therefore, the price of one share of Webb Company stock changed by $0.154 from Monday to Friday.

(a) Mean = 36.05; (b) median = 37; (c) mode = 37  

Step-by-step explanation:

I am assuming your DFT is like this:

[tex]\begin{array}{c|c}\textbf{n} & \textbf{Frequency} \\33 & 0 \\34 & 3 \\35 & 3 \\36 & 3 \\37 & 10 \\\end{array}[/tex]

(a) Mean

The mean is the sum of all the data points divided by the number of points. I have done some of the calculations for you in the table below

[tex]\begin{array}{cccc}\textbf{n} & \textbf{f} & \mathbf{n\cdot f} & \mathbf{cf}\\33 & 0 & 0 &0 \\34 & 3&102 &3 \\35 & 3& 105 & 6\\36 & 3 &108 & 9\\37& 10& 370 & 19\\\textbf{SUM} & \mathbf{19}&\mathbf{685} \\\end{array}[/tex]

[tex]\begin{array}{rcl}\text{Mean} & = & \dfrac{\sum n}{n}\\\\& = & \dfrac{685}{19}\\\\& = & \mathbf{36.05}\\\end{array}[/tex]

(b) Median

The median is the middle value in your list of observations.

Your data set contains 19 terms, so the middle is (19/2)th term.

Count down the column of cumulative frequency (cf) until cf = 9½.

The 9½th term is 37.

Median = 37

(c) Mode

The mode is the value that appears most often in your list of observations.

It is obvious from your table that the number that occurs most frequently is 37.  

Mode = 37

The diagram below shows that the score of 37 is predominant.

The mean, median and mode are measures of central tendency in mathematics. They are found using a Frequency Distribution Table; calculate the mean by summing up the product of each data point and its frequency, then dividing by total frequency. The median is the middle number when data is in ascending order, and the mode is the number appearing most often.

In mathematics, the measures of central tendency referenced in your question; mean, median, and mode, are used to describe a set of data. Given your Frequency Distribution Table (FDT), here's how you would calculate each:

The measure of arc EG = 16°.

Solution:

Given data:

m∠X = 47°  and m(ar FH = 110°)

To find the measure of arc EG:

We know that,

Angle formed by two intersecting secants outside the circle is equal to half of the difference between the intercepted arcs.

[tex]$m \angle X=\frac{1}{2}({arc} \ FH-{arc} \ EG)[/tex]

[tex]$47^{\circ}=\frac{1}{2}\left(110^\circ- {arc} \ EG}\right)[/tex]

Multiply by 2 on both sides.

94° = 110°  - arc EG

Subtract 110° from both sides.

-16° = -arc EG

Multiply -1 on both sides, we get

16° = arc EG

Switch the sides.

arc EG = 16°

The measure of arc EG = 16°.

The solution of the equation 4y − x + 9 = 0 and y = 6 − 2x will be (11/3, −4/3). Point (2, 3) is not the solution of the system.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The linear equations are given below.

−x + 4y = −9        ...1

y = −2x + 6         ...2

From equations 1 and 2, then we have

−x + 4(−2x + 6) = −9

−x − 8x + 24 = −9

−9x + 24 = −9

9x = 24 + 9

9x = 33

x = 11 / 3

Then the value of the variable 'y' is calculated as,

y = −2(11/3) + 6

y = −22/3 + 6

y = −4/3

The arrangement of the situation 4y − x + 9 = 0 and y = 6 − 2x will be (11/3, −4/3). Point (2, 3) isn't the arrangement of the framework.

The point (2, 3) does not satisfy either of the given equations, −x + 4y = −9 and y = −2x + 6. Therefore, it is not a solution to the system of equations.

To determine if the point (2, 3) is a solution to the system of equations consisting of −x + 4y = −9 and y = −2x + 6, we need to check whether the point satisfies both equations.

Let's substitute the values into the first equation:
−(2) + 4(3) = −8 + 12 = 4, which does not equal −9. Therefore, the point does not satisfy the first equation.

For the second equation:
−2(2) + 6 = −4 + 6 = 2, which does not equal 3. Hence, the point does not satisfy the second equation either.

Since the point (2, 3) does not satisfy either equation, it is not a solution to the system of equations.

The answer is D: 5

Step-by-step explanation:

5 x 5 = 25 - 4 = 21 and 3 x 5 = 15 + 6 = 21

Answer: 5

Step-by-step explanation: Here, we want to determine which number can be replaced for the variable in this problem so the statement holds true.

5 would be the only number in this set that can work. Let's test it out.

We can do this by simply plugging in 5 for x. If the statement holds true when 5 is plugged in for x, then 5 is a solution.

Plugging in 5 for x, we have 5(5) - 4 = 3(5) + 6.

Simplifying, we have 25 - 4 = 15 + 6 or 21 = 21 which is a true statement.

So 5 is a solution.
