(-2 × X) + (-2 × 2)

Answer:

(-6, -5)

(Don't forget to give me brainiest)

Step-by-step explanation:

1. Make the two equations equal to each other: -4x - 29 = -x - 11

2. Add "X" on both sides: -4x - 29 = -x - 11

                                              +x             +x

                                       = -3x - 29 = -11

3. Add both sides by "29":      -3x - 29 = -11

                                                  +29          +29

                                                   =    -3x = 18

4. Divide both sides by "-3" to isolate "X":     -3x = 18

                                                                         -3         -3

                                                                            x = -6

5. Plug in "-6" to "X" on first equation:  y = -4(-6)-29

                                                                y = 24 - 29

                                                                y = -5

6. Solution is: (-6, -5)

In Mathematics, a set is a group of unique elements. Here, the set M consists of three-digit numbers where the first digit is greater than the second by 4, and the third digit is greater than the first by 2. Examples of such numbers could be 530, 641, 752, etc.

The subject of the question is Mathematics, more specifically, the definition and properties of a set. In Mathematics, a set is a collection of distinct elements. A three-digit number has three digits: the first, second and third digit. In this case we need numbers where the first digit is greater than the second by 4, and the third digit is greater than the first by 2.

For example, let's take 501. Here, 5 is the first digit, 0 is the second and 1 is the third. The first digit is greater than the second by 5, not 4, therefore 501 does not belong to the set. But if we consider 640, here 6 is the first digit, 4 is the second and 0 is the third. The first digit is greater than the second by 2 and the third digit is less than the first by 6. So 640 belongs to the set. Therefore, our set M can include numbers like 530, 641, 752, and so on.

The 90% confidence interval for the difference between the two sample proportions are -0.078 <p₁ - p₂ < 0.003.

To find the 90% confidence interval for the difference between two sample proportions, use the formula:

CI = (p₁ - p₂) ± z√((p₁(1-p₁)/n₁) + (p₂(1-p₂)/n₂))

where:

p₁ = number of successes in sample 1 / sample size 1

p₂ = number of successes in sample 2 / sample size 2

n₁ = sample size 1

n₂ = sample size 2

z = z-score for the desired confidence level (90% in this case)

Using the given values:

p₁ = 780/820 = 0.9512

p₂ = 795/804 = 0.9888

n₁ = 820

n₂ = 804

z = 1.645 (from standard normal distribution table for 90% confidence level)

Plugging in the values:

CI = (0.9512 - 0.9888) ± 1.645√((0.9512(1-0.9512)/820) + (0.9888(1-0.9888)/804))

= (-0.0376) ± 0.0403

= (-0.078, 0.003)

Therefore, the 90% confidence interval for the difference between the two sample proportions is (-0.078, 0.003).

Now we can see that the distance between the football field (F) and the high school (H) is 5 units in the x direction and 1 unit in the y direction, which corresponds to a distance of 5 x 2 = 10 miles in the x direction and 1 x 2 = 2 miles in the y direction. Using the Pythagorean theorem, we can find the distance between the two points:

distance = sqrt((10)^2 + (2)^2)

        = sqrt(104)

So the distance between the football field and the high school is approximately 10.198 miles. Therefore, the statement that is true is:

It takes apprοximately 3.5 years fοr an investment with an annual interest rate οf 20%, cοmpοunded cοntinuοusly, tο dοuble frοm $9,300 tο $18,600.

Cοmpοund interest is a sοrt οf interest that is calculated using bοth the principal—the initial amοunt invested οr bοrrοwed—and the interest that has accrued οver time. In οther wοrds, the interest fοr the fοllοwing periοd is cοmputed οn the new, larger amοunt after the interest generated during each periοd has been added tο the principal.

Cοmpοund interest can be explained as interest οn interest. The principle grοws οver time at a rising rate as the interest generated in each periοd is added tο it. Because οf this, cοmpοund interest is an effective instrument fοr lοng-term investing and saving.

Fοr instance, if yοu put $1,000 intο an accοunt with a cοmpοund interest rate οf 5%, yοu will receive $50 in interest the first year. Yοur tοtal sum at the end οf the first year will be $1,050 (the initial $1,000 plus $50 in interest). Yοu will receive $52.50 in interest since in the secοnd year the interest is cοmputed οn $1,050 rather than $1,000. This will increase yοur οverall balance tο $1,102.50 by the cοnclusiοn οf the secοnd year, and sο οn fοr succeeding years.

In cοnclusiοn, cοmpοund interest can be a pοtent tοοl fοr lοng-term grοwth οf yοur savings οr investments, but it's critical tο cοmprehend hοw it wοrks and pick assets with cοmpetitive interest rates and lοw expenses.

Tο find the time it takes fοr an investment tο dοuble with cοntinuοus cοmpοunding, we can use the fοrmula:

[tex]t = ln(2) / (r \times ln(1 + r))[/tex]

where:

t is the time it takes fοr the investment to double

r is the annual interest rate as a decimal

In this case, the annual interest rate is 20%, or 0.20 in decimal fοrm. So,

we can plug in the values and sοlve for t:

[tex]t = ln(2) / (0.20 \times ln(1 + 0.20))\\t = 3.5 years[/tex]

Therefore, it takes apprοximately 3.5 years for an investment with an annual interest rate of 20%, compounded continuously, to dοuble from $9,300 tο $18,600.

Step-by-step explanation:

Step-by-step explanation:

speed = distance / time

distance = speed × time

they both have the same speed.

distanceB = distanceA + 4

so,

distanceA = speed × 25 min

distanceB = distanceA + 4 = speed × 35 min

distanceA = speed × 35 - 4

both distanceA expressions must be equal :

speed × 25 = speed × 35 - 4

subtract 25speed from both sides

0 = speed × 10 - 4

add 4 to both sides

4 = speed×10 min

divide both sides by 10 min

4 miles / 10 min = speed

to get the usual miles per hour, we need to multiply numerator and denominator by the same number, so that the denominator is 1 hour = 60 minutes.

as we cab see, we need to multiply by 6/6 :

4/10 × 6/6 = 24/60 = 24 miles per hour.

The inverse function of the given is y^-1=x/2 -4.

The domain of the original function becomes the range of the inverse function, and the range of the given function becomes the domain of the inverse function. The inverse function is denoted by the notation f-1 in relation to the original function f. Swapping (x, y) with (y, x) with reference to the line y = x yields the graph of the inverse function. Only when f is both a one-one and an onto function does it have an inverse, indicated by the symbol f-1. Keep in mind that f-1 is NOT f's inverse. The domain value of x is given by combining the function f and the reciprocal function f-1.

Here the given function is,

=> y = 2x+8

Now interchange x and y then

=> x=2y+8

Now simplify the expression with respect to y then,

=> x-8=2y

=> y =x/2 -4

=>y^-1=x/2 -4

Hence inverse function is, y^-1=x/2 -4

The total price of the 50-inch Panasonic Plasma TV is $687.44.

In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.

Given that, 50-65 inch TV's $150 rebate and delivery charge is $35.

50 inch Panasonic Plasma TV costs $734.95

Rebate is $150

So, cost of TV is 734.95-150

= 584.95

Cost of TV including delivery charge

= 584.95-35

= 549.95

Here, tax is 25%

So, cost of TV including tax

= 549.95+25% of 549.95

= 549.95+25/100 ×549.95

= 549.95+0.25×549.95

= 687.4375

Therefore, the total price of the 50-inch Panasonic Plasma TV is $687.44.

Answer:

y = (3a + sqrt(11a^2 - 8b + 41)) / 2

y = (3a - sqrt(11a^2 - 8b + 41)) / 2

Step-by-step explanation:

To find the tangent lines that are perpendicular to the given line, we need to find the slope of the given line and then find the negative reciprocal of that slope. The negative reciprocal will be the slope of the tangent lines we are looking for.

The given line is 2x + y = 10, which can be rewritten as y = -2x + 10. Therefore, the slope of the given line is -2.

The center of the circle can be found by completing the square of the x and y terms. We have:

x^2 - 4x + y^2 = 1

(x - 2)^2 + y^2 = 5

Therefore, the center of the circle is (2,0), and the radius is sqrt(5).

Now, we can find the equation of the tangent lines. Let (a,b) be the point where the tangent line intersects the circle. Since the tangent line is perpendicular to the given line, its slope is the negative reciprocal of -2, which is 1/2. Therefore, the equation of the tangent line passing through (a,b) is:

y - b = (1/2)(x - a)

To find the points of intersection of this line and the circle, we substitute y = -2x + 10 into the equation of the tangent line and solve for x:

(x - a)^2 + (-2x + 10 - b)^2 = 5

Expanding and simplifying this equation, we get:

5x^2 - 4ax + 4a^2 + 4bx - 40b + 84 = 0

This is a quadratic equation in x, so we can solve for x using the quadratic formula:

x = [4a ± sqrt(16a^2 - 4(5)(4a^2 + 4b - 84))] / 10

Simplifying this expression, we get:

x = [2a ± sqrt(11a^2 - 8b + 41)] / 5

Now we can substitute these values of x into the equation of the tangent line to find the corresponding values of y:

y = -2x + 10

y = -a + b + (1/2)(2a ± sqrt(11a^2 - 8b + 41))

This gives us two equations for the tangent lines passing through (a,b), one for each value of x. We can simplify these equations to get:

y = (3a ± sqrt(11a^2 - 8b + 41)) / 2

Therefore, the equations of the tangent lines that are perpendicular to the given line are:

y = (3a + sqrt(11a^2 - 8b + 41)) / 2

y = (3a - sqrt(11a^2 - 8b + 41)) / 2

where (a,b) is any point on the circle (x - 2)^2 + y^2 = 5.

I'm sure there was a better way of figuring out this next part but this is how I did it, I took 570 and multiplied it by 0.10 to see what that would be. It ended up being 57 and thats not 28.50 so I multiplied 570 by 0.05 and ended up with 28.50. You coulda also divided the 57 by two to figure out is 0.05 which equals 5%.

What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                    Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables. Equations with variables of power 1 are referred to as linear equations. One example with only one variable is where ax+b = 0, where a and b are real values and x is the variable.

Let x be the number of years after Tammy purchased her home.

We have been given that Tammy’s home cost her $184,000. She lives in an area with a lively real estate market, and her home increases in value by 3.5% every year.

We can see that value of house will increase exponentially as the value of increases 3.5% per year.

Since an exponential function is in form

           y = a * bˣ

a = Initial value,

b = For growth b is in form (1+r) where r represents growth rate in decimal form.

Let us convert our given growth rate in decimal form.

   3.5% = 0.035

Upon substituting our values in exponential form of function we will get the value (y) of Tammy's home after x years as

  y = 184000(1 + 0.035)ˣ

 y =  184000(1.035)ˣ

  Therefore, the function   y =  184000(1.035)ˣ represents value of Tammy's home after x years of purchase.

Let us find the value of home after 13 years by substituting x=13 in our function.

     y =  184000(1.035)¹³

     y =  184000 * 1.56395606

  y = 287767.915

  Let us subtract cost of the home from the value of home after 13 years to find the amount of profit.

   The amount of profit, if tammy sells her home after 13 years = 287767.915  - 184000  

 The amount of profit, if tammy sells her home after 13 years = 103767.915 - 103,768

Therefore, Tammy will have made a profit of $103,768.
