A company sells its printers to customers in order to make a profit of 25% calculate the price the company paid for a printer wh

ioda

The company paid $2000 for the printer

Step-by-step explanation:

Let x be the price of the printer for which the company bought it.

If x is the price of printer, then 25% of x will be the profit made by the company.

That is:

0.25x

According to the statement,

The cost and profit earned by company are equal to 2500

So,

$x+0.25x = 2500\\1.25x = 2500$

Dividing both sides by 1.25

$\frac{1.25x}{1.25} = \frac{2500}{1.25}\\x = 2000$

Hence,

The company paid $2000 for the printer

I need help<br> (Find the slope of the line through the given pair of points)<br> (-7,-18),(4,4)

larisa [96]

Answer:

Step-by-step explanation:

You can find slope using the slope equation : $\frac{y2-y1}{x2-x1}$

Plug in the two points : $\frac{4-(-18)}{4-(-7)}$

Calculate by adding the numbers: $\frac{22}{11}$

Reduce the fraction : 2

The slope is 2

I need help someone please

statuscvo [17]

Answer: $\frac{6}{2}$

Step-by-step explanation:

1. Use this $\frac{f(b)-f(a)}{b-a}$ to find the average rate of change

2. Average rate of change = $\frac{f(8)-f(6)}{8-6}$

3. $f(8) = - 4$ and $f(6) = -10$ (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like $\frac{-4-(-10)}{8-6}$

6. Solve $\frac{6}{2}$

What is -3x+12y=24 in standard form

nalin [4]

So standard form is Ax+By=C
Since the problem is already in that form you don’t need to switch it around however A has to be more than 0 (so positive). Divide the equation by -3 to get the answer x-4y=-8
