Step-by-step explanation:

let windows = x

Mrs. Saunders can clean one-third of the windows in an hour = x/3

daughter can clean one-sixth of the windows in an hour = x/6

so,

x/3+x/6 = 1

thus, x = 2

mother and daughter together can clean the windows in 2 hours

The rational function with the given characteristics is [tex]f(x) = \frac{3x + 1}{x - 4} [/tex].

Any function that can be expressed mathematically as a rational fraction—an algebraic fraction in which both the numerator and the denominator are polynomials—is referred to as a rational function. The polynomials' coefficients don't have to be rational numbers,they can be found in any field K.

given that a vertical asymptote at x=-4.

A horizontal asymptote at y=3.

The denominator of the function cancels for this value and the numerator does not cancel at this value if the rational function has a vertical asymptote at x=4.

[tex]f(x) = \frac{p(x)}{(x - 4)} [/tex]

The degree of the numbered variable is equal to the degree of the denominator if the rational function has a horizontal asymptote at y=3, and the coefficient of the higher degree variable is three times larger.

Hence,

[tex]f(x) = \frac{3x + 1}{x - 4} [/tex]

Two expressions with equal sign is called as Equation.

A simple linear regression equation is used to estimate the value of the dependent variable based upon the independent variable.

The general form of a simple linear regression equation is:

y=a+bx

Here,

y = dependent variable

x = independent variable

a = intercept

b = slope

The output of the least squares regression analysis for predicting rating from price is provided.

So, the dependent variable is the ratings and the independent variable is the price.

The regression equation for predicting rating from price is:

y=0.39+2.52x

Predict the rating of a brand that costs $3.00 per bag as follows:

y=0.39+(2.52*$3.00)

=0.39+7.56

=7.17

=7 approximately.

Thus, the rating of a brand that costs $3.00 per bag is 7.

One strategy to eliminate a variable is by multiplying the first equation by 5 and the second equation by 2 and then adding the resulting equations or by multiplying the first equation by 3 and the second equation by 7 and then adding the resulting equations

From the question, we are to determine the strategies that would eliminate a variable in the given system of equations

The given system of equations is

-7x + 2y = 5

3x - 5y = -5

We can eliminate the variable y multiplying the first equation by 5 and the second equation by 2

That is,

5 × [-7x + 2y = 5

2 × [3x - 5y = -5

--------------------------

-35x + 10y = 25

6x - 10y = -10

------------------------

-29x = 15

Also,

We can eliminate the variable x by multiplying the first equation by 3 and the second equation by 7

That is,

3 × [-7x + 2y = 5

7 × [3x - 5y = -5

-------------------------

-21x + 6y = 15

21x - 35y = -35

---------------------

-29y = -20

Hence, one strategy is by multiplying the first equation by 5 and the second equation by 2 and then simplify by adding

Step-by-step explanation:

$1.20 dollars

Answer:

(4, 2 )

Step-by-step explanation:

y = x - 2 → (1)

y = - 0.5x + 4 → (2)

substitute y = x - 2 into (2)

x - 2 = - 0.5x + 4 ( add 0.5x to both sides )

1.5x - 2 = 4 ( add 2 to both sides )

1.5x = 6 ( divide both sides by 1.5 )

x = 4

substitute x = 4 into (1)

y = 4 - 2 = 2

solution is (4, 2 )

The slope of the line that passes through (-4, 2) and (-5, 0), in simplest form is calculated as: 2.

The slope of a line (m) = change in y/change in x = y2 - y1/x2 - x1 or rise/run of the line.

Given the following points on the line:

(-4, 2) = (x1, y1)

(-5, 0) = (x2, y2)

Substitute the values into m = y2 - y1/x2 - x1:

Slope (m) of the line = (0 - 2) / (-5 - (-4))

Slope (m) of the line = (-2) / (-5 + 4)

Slope (m) of the line = -2/-1

Slope (m) of the line = 2

Thus, the slope of the line that passes through (-4, 2) and (-5, 0), in simplest form is calculated as: 2.

Step-by-step explanation:

I hope you wrote the equation correctly.

there could be parts missing. and exponents be wrong.

I am concerned, because the missing parts are not just numbers. they are full terms in the variable p.

so, well, the right side is

p³ - 2p + 3p = p³ + p

on the left side we have

a(p² -2) - p(2p³ - b)

ap² - 2a - 2p⁴ - pb

so, the first thing we see : we need to eliminate the p⁴ terms, because there are none on the right side.

so,

a = 2p²

that gives us

2p⁴ - 4p² - 2p⁴ - pb = -4p² - pb

let's see, if we can create the missing items just by "b" (and we have to get rid of -4p²) when we bring left and right sides together again :

-4p² - pb = p³ + p

p³ + p + 4p² = -pb

b = (p³ + p + 4p²)/-p = -p² - 1 - 4p

so,

the equation would look like

2p²(p² - 2) - p(2p³ - (-p² - 1 - 4p)) = p(p² - 2) + 3p

which could be also written as

2p²(p² - 2) - p(2p³ + p² + 1 + 4p) = p(p² - 2) + 3p

For the functions g (x) = 5 x - 2 and h (x) = x² + 1, the value of the composite function g o h (a) will be 5 a² + 3.

We are given the functions:

g (x) = 5 x - 2

h (x) = x² + 1

We first need to find the composite function g o h (x).

So, we get that:

g o h (x) = g ( h (x) )

g o h (x) = 5 ( x² + 1 ) - 2

g o h (x) = 5 x ² + 5 - 2

g o h (x) = 5 x² + 3

Now, we need to find the value of the composite function for x = a. So, we get that:

g o h (x = a) = 5 (a)² + 3

g o h (a) = 5 a² + 3

Therefore, for the functions g (x) = 5 x - 2 and h (x) = x² + 1, the value of the composite function g o h (a) will be 5 a² + 3.

Answer:

y = 3 and x = 4

Step-by-step explanation:

Let's solve your system by substitution.

6x+5y=39;3x+5y=27

Step: Solve6x+5y=39for x:

6x+5y=39

6x+5y+−5y=39+−5y(Add -5y to both sides)

6x=−5y+39

6x/6=−5y+39/6

(Divide both sides by 6)

x=−5/6y+13/2

Step: Substitute −5/6y+13/2 for x in 3x+5y=27:

3x+5y=27

3(−5/6y+13/2)+5y=27

5/2y+39/2=27(Simplify both sides of the equation)

5/2y+39/2+−39/2=27+−39/2

(Add (-39)/2 to both sides)

5/2y=15/2

5/2y/5/2=15/2/5/2

(Divide both sides by 5/2)

y=3

Step: Substitute 3 for y in x=−5/6y+13/2:

x=−5/6y+13/2

x=−5/6(3)+13/2

x=4(Simplify both sides of the equation)

She needs to locate the squares of the integers between 7.1 and 7.2 in order to estimate √51.

Finding an integer's square root is the inverse of squaring an integer. A number's square value is obtained by multiplying it by itself, whereas the square root of a number can be discovered by looking for a number that, when squared, produces the original value. It follows that a× a = b if "a" is the square root of "b." Every number has two square roots, one of a positive value and one of a negative value because the square of any number is always a positive number.

In the question given to us,

look at the table, we know

(7.1)² = 50.41 and (7.2)² = 51.84

So, (7.1) < √51 < 7.2 { estimate }

The jogging speed of the jogger is 6 miles/hour.

Given that:-

Distance from home to park = 12 miles

Distance from park tp home from a different route = 18 miles

It is also given that the time taken to reach home from park is 1 hour longer than the number of hours taken to reach park from home.

We have to find the speed of the jogger.

Let the time taken by jogger to reach park from home be t hours.

Hence, according to the data given in the question,

Time taken by jogger to reach home from park is (t+2) hours.

We know that,

Speed = distance/time

We know that the speed of jogger in each route is same.

Hence, we can write,

12/t = 18/(t+1)

2/t = 3/(t+1)

2(t+1) = 3t

2t+2 = 3t

t = 2 hours.

Hence, speed of the jogger = 12/2 = 6 = 18/(2+1) = 18/3.
