To solve for Sydney's age, we used an equation based on the relationship that Devaughn is 11 years younger than Sydney and the sum of their ages is 83. Solving the equation 2S - 11 = 83, we found that Sydney is 47 years old.

To find Sydney's age, we need to set up and solve an equation based on the information given: Devaughn is 11 years younger than Sydney, and the sum of their ages is 83.

Let's let Sydney's age be represented by S and Devaughn's age be represented by D. Given that Devaughn is 11 years younger than Sydney, we can express Devaughn's age as D = S - 11.

The sum of their ages is given as 83, so we can write the following equation: S + D = 83.

Substituting Devaughn's age in terms of Sydney's age, we get: S + (S - 11) = 83. This simplifies to 2S - 11 = 83. Solving for S, we add 11 to both sides, resulting in 2S = 94, and then we divide by 2 to find S = 47.

Therefore, Sydney's age is 47 years old.

Answer:

The length of MN is [tex]\sqrt{5}[/tex] units.

Step-by-step explanation:

The given Quadrilateral KLMN has vertices at K(-4,-1), L(-1,-1) M(-2,-5) and N(-4,-4).

We use the distance formula to find the length of MN.

[tex]|MN|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We plug in the values to get

[tex]|MN|=\sqrt{(-4--2)^2+(-4--5)^2}[/tex]

[tex]|MN|=\sqrt{(-2)^2+(1)^2}[/tex]

[tex]|MN|=\sqrt{4+1}[/tex]

[tex]|MN|=\sqrt{5}[/tex]

The length of MN is [tex]\sqrt{5}[/tex] units.

Answer:

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

Step-by-step explanation:

It is called an inverse or reciprocal function of [tex]f[/tex] to another function [tex]f^{-1}[/tex] that fulfills that:

If [tex]f(a)=b[/tex], then [tex]f^{-1} (b)=a[/tex]

To calculate the inverse of the function [tex]y=2x+1[/tex]

[tex]f(x)=y[/tex]

So, rewritting the function

[tex]f(x)=2x+1[/tex]

Changing the x for y

[tex]x=2y+1[/tex]

Let's clear y

[tex]y=\frac{x-1}{2}[/tex]

Ordering the function above

[tex]y=\frac{x}{2}-\frac{1}{2}[/tex]

So, the inverse of the function [tex]f(x)=2x+1[/tex] is:

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

The number is 3.

3x3 is 9, which is 3 less than 12.

Answer:

The number is 5.

Step-by-step explanation:

12 plus 3 is 15.

5 x 3 = 15

15 - 3 = 12

3 less than 3 times a number is 12.

It sounds like 3 less from a number IS 12. So adding 3 to 12 will get 15, and 15 divided by 3 equals 5.

I hope this is correct and that it helps! :)

Answer:

[tex](x+3)^2 + y^2 =25[/tex]

Step-by-step explanation:

The general equation of a circle has the form:

[tex](x-h)^2 + (y-k)^2 =r^2[/tex]

Where the point (h, k) is the center of the circle and r is the radius

In this case the center is (-3, 0) and the radius is [tex]r=5[/tex]

So [tex]h=-3\\k=0[/tex]

Finally the equation of the circle is:

[tex](x-(-3))^2 + (y-0)^2 =5^2[/tex]

[tex](x+3)^2 + y^2 =25[/tex]

(X+3)^2 +y^2 =25

The taxpayer and his spouse, with a combined taxable income of $27,900, will fall into the 15% tax bracket for a married couple filing jointly for the 2020 tax year.

The subject of this question is the United States Federal Income Tax Brackets. The taxpayer and his spouse have a combined taxable income of $14,200 + $13,700 = $27,900. For the 2020 tax year, a married couple filing jointly with taxable income between $0 and $19,750 fall in the 10% tax bracket, while those with taxable income between $19,751 to $80,250 are in the 15% tax bracket. So, the taxpayer and his spouse, with their combined taxable income, will fall into the 15% tax bracket. Their taxable income exceeds the threshold for the 10% tax bracket and does not reach the threshold for the 38% bracket. Please note, it's important to stay informed about tax brackets as they can change annually.

So if we have the number after the 36% increase in population, we would want to subtract that 36% from 51000.

36% of 51000 can be found by multiplying 51000 by 0.36 (0.36 is the decimal equivalent of 36%)

51000 x .36 = 18360

So you simply subtract 18360 from 51000, which is 32,640.

May be to late, but I'll post my answers to your questions anyway :)

Final answer:

Without specific temperature data, we cannot create the comparative dot plots and box plots requested by the student. Instructions have been provided on how to create and analyze them once the data is available.

Explanation:

To answer the student's question about comparing the high temperatures for Dallas, Texas in June 1985 and June 2013 using comparative dot plots and comparative box plots, we first need the individual temperature data for each June to create these graphs. Unfortunately, without the specific data, we are unable to create the plots.

However, we can discuss how to approach this problem. To create a comparative dot plot, you would list the temperatures for each data set on a horizontal line, each set represented by dots. Then, assess the degree of overlap by visually inspecting where the dots from both data sets lie in relation to each other. Compare their shapes, centers, and spreads by observing the clustering of the dots, the location of the “middle” of the dots, and how far the dots extend out from the center.

For the comparative box plot, you would draw two box plots on the same axis. A box plot displays the minimum, first quartile, median (or second quartile), third quartile, and maximum. Assess the degree of overlap by comparing where the boxes and whiskers of the plots are positioned in relation to each other, again paying attention to the centers (medians), spreads (interquartile ranges), as well as the overall range of data. Both types of plots can help ascertain whether the high temperature in June of each year was significantly different from the other, and how each year's temperatures compare to the historical average.

Answer:

B. 7.5 square units.

Step-by-step explanation:

We have been given an image of a right triangle. We are asked to find area of our given triangle.

We can see that base of our given triangle is 5 units as difference between point S and point T is 5 units.

[tex]2--3=2+3=5[/tex]

The height of our given triangle (RT) is 3 units.

[tex]1--2=1+2=3[/tex]

[tex]\text{Area of triangle}=\frac{1}{2}\times \text{Base}\times \text{Height}[/tex]

[tex]\text{Area of triangle}=\frac{1}{2}\times \text{5 units}\times \text{3 units}[/tex]

[tex]\text{Area of triangle}=\frac{1}{2}\times 15\text{ units}^2[/tex]

[tex]\text{Area of triangle}=7.5\text{ units}^2[/tex]

Therefore, area of our given triangle is 7.5 square units and option B is the correct choice.

Answer:

  c(3) is the largest

Step-by-step explanation:

For positive values of x, j(x) > a(x), so the comparison is between c(x) and j(x).

Without evaluating the functions, you can subtract 5x from them to get ...

  c'(x) = c(x) -5x = 3x² +22

  j'(x) = j(x) -5x = 7x

Now the question is whether c'(3) is larger than j'(3). The latter is ...

  j'(3) = 7·3 = 21

Since c'(3) has an added constant of 22 and x² will be positive, we know that ...

  c(3) > j(3) > a(3)

The function with the largest value at x=3 is c(x).

_____

You can, of course, simply evaluate the functions:

  c(3) > j(3) > a(3) . . . . . . . c(3) is the largest

Answer:

- The center of hyperbola is (-2 , 3)

- The left vertex, if the hyperbola opens horizontally, or the

  bottom vertex, if it opens vertically, is (-6 , 3)

- The other vertex is (2 , 3)

Step-by-step explanation:

* Lets study the equation of the hyperbola

- The standard form of the equation of a hyperbola with  

  center (h , k) and transverse axis parallel to the x-axis is

  (x - h)²/a² - (y - k)²/b² = 1, Where

- The length of the transverse axis is 2a

- The coordinates of the vertices are (h ± a , k)

- The length of the conjugate axis is 2b

- The coordinates of the co-vertices are (h , k ± b)

- The coordinates of the foci are (h ± c , k), where c² = a² + b²

* Now lets solve the problem

∵ (x + 2)²/4² - (y - 3)²/5² = 1

∵  (x - h)²/a² - (y - k)²/b² = 1

∴ a = 4 , b = 5

∴ h = -2 , k = 3

∵ The center of the hyperbola is (h , k)

∴ The center of hyperbola is (-2 , 3)

∵ The coordinates of the vertices are (h + a , k)  , (h - a , k)

∴ The coordinates of the vertices are (-2 + 4 , 3)  , (-2 - 4 , 3)

∴ The coordinates of the vertices are (2 , 3)  , (-6 , 3)

∴ The left vertex, if the hyperbola opens horizontally, or the

  bottom vertex, if it opens vertically, is (-6 , 3)

∴ The other vertex is (2 , 3)

The center of a hyperbola is determined by the coordinates (h, k) in its equation. The vertices are the points where the hyperbola intersects its major axis, and their positions depend on whether the hyperbola opens horizontally or vertically. If it opens horizontally, the left vertex is at (h - A, k), and if it opens vertically, the bottom vertex is at (h, k - B).

In the equation of a hyperbola, the center of the hyperbola can be found by identifying the coordinates (h, k). These are the constants in the denominators of the fractions on the left-hand side of the equation. For instance, in the equation ((x-h)²/A²) - ((y-k)²/B²) = 1, the center would be at the point (h, k).

The vertices of the hyperbola are the points where the hyperbola intersects its major axis. If the hyperbola opens horizontally, the left vertex will be located at the coordinate (h - A, k), and the other vertex will be at (h + A, k). If the hyperbola opens vertically, the bottom vertex will be at the coordinate (h, k - B), with the other vertex at (h, k + B).

Remember, A represents the distance from the center to a vertex along the major axis, and B represents the distance from the center to a vertex along the minor axis.
