A common equation used in business is a demand equation. It expresses the relationship between the unit price of some commodity

and the quantity demanded. In the​ equation, p represents the unit price and x represents the quantity demanded in thousands. A company sells desk lamps and has found that the demand equation for a certain style of desk lamp is given by the equation p equals negative x squared plus 23. Find the demand for the desk lamp if the price is ​$7 per lamp.

Answer:

The demand of the desk is 4000 units

Step-by-step explanation:

From the question we know that p is equals negative x squared plus 23, that can be written as:

p=-x^{2} +23

Where p is the unit price and x represent the quantity demanded in thousands. Replacing p by 7 and solving for x, we get:

7=-x^{2} +23\\x^{2} =23-7\\x^{2} =16\\x=\sqrt{16\\} \\x=4

Since x is given in thousands of units, if the price is $7, the demand of the desk is 4000 units.

4. Two points on a line are (-10, 1) and (5, -5). If
Vsevolod [243]

Answer:

The x-coordinate of another point is zero

Step-by-step explanation:

step 1

Find the slope between the two given points

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

(-10,1),(5,-5)

substitute in the formula

m=\frac{-5-1}{5+10}

m=\frac{-6}{15}

Simplify

m=-\frac{2}{5}

step 2

Find the x-coordinate of another point

we have

(x,-3)

we know that

If the other point is on the line, then the slope between the other point and any of the other two points must be the same

so

Find the slope between the points

(x,-3),(5,-5)

Remember that

m=-\frac{2}{5}

substitute in the formula

-\frac{2}{5}=\frac{-5+3}{5-x}

-\frac{2}{5}=-\frac{2}{5-x}

the denominators must be the same

5=5-x

x=0

therefore

The x-coordinate of another point is zero
