Answer:

$2,780

Step-by-step explanation:

Let the original price be P

2,363 =P - 15% x P

2,363 =P - 15/100 x P

2,363 = P - 0.15P

2,363 = 0.85P

Divide both sides by 0.85

2,363/0.85 = 0.85P/0.85

2,780 = P

I hope this helps.

Select the domain and range of F. F = {(x, y ) | x + y = 10}. Domain: {10} Range: {10} Set F is not a function and does not cont

sertanlavr [38]

Answer:

Domain: All Real Numbers

Range: All Real Numbers

Step-by-step explanation:

F is

F = {(x, y ) | x + y = 10}

(x,y) is the ordered pair

x + y = 10 is the expression

We can rearrange it

y = 10 - x

And then we can plot it using a graphing calculator. See attached image

By looking at the plot and examining the expression, we can see that there are no restrictions over x or y.

This means that the domain and range are all real numbers

Domain: All Real Numbers

Range: All Real Numbers

F is a function because it is a relation that associates each element x to a single element y.

What is the number between 3400 and 4400

xxTIMURxx [149]

First find how many numbers are between the two by subtracting
4400 - 3400 = 1000
now to find half way between the two divide 1000 by 2
1000/2 = 500
so the number between the two is 500 +3400 and 4400-500
which is 3900

Step-by-step explanation:

Initial coordinates and transformations:

(x, y) → (4x, 4y) → (3x, 3y)
A(-1, -1) → A'(-4, -4) → A''(-3, -3)
B(1, 1) → B'(4, 4) → B''(3, 3)

its question #2 my son and I cannot figure out how to do this other than dividing. however, when u divide 59 into 422, are you s

anyanavicka [17]

Honestly I can see an argument for 7 shelves or for 8 shelves.

When you do the calculation; $\frac{422}{59}=7.15$ You get 7.15 shelves. Clearly you cannot have .15 of a shelf so the logician in me wants to say you need 8 shelves!

But if the assignment is aimed estimation skills, (Which is what I assume is being implied by the title of the assignment), then the easier calculation of $\frac{420}{60}=7$ is probably what the teacher was hoping for.

You might have been accidentally been calculating $\frac{59}{422} =.139$ . Remember division is NOT communitive! i.e. $1\div2\neq2\div1$ .

From the image;
The first step was to see that 59 can not go into 4..resulting in the zero above the 4, multiplying 0 by 59 and subtracting 0 from 4.

The second step begins by bringing down the 2, seeing that 59 can not go into 42..resulting in the zero above the 2, multiplying 0 by 59 and subtracting 0 from 42.

The third step begins by bringing down the 2, seeing that 59 can go into 422 7 times (I tested this on the right by a short multiplication problem)..resulting in the 7 above the 2, multiplying 7 by 59 and subtracting 413 from 42.

This process continues....

AP calculus HW Need help on #61

Yuki888 [10]

Expanding the limit, we get (x^2+2x∆x+∆x^2-2x-2∆x+1-x^2+2x-1)/∆x

Crossing the 1s , the 2xs, and the x^2s out, we get

(2x∆x+∆x^2-2∆x)/∆x

Dividing the ∆x, we get
2x+∆x-2.

Making the limit of ∆x=0, we get 2x-2.
