4p + 3c and (c+2p)(2)

Mathematics
1 answer:
Tatiana [17]1 year ago
6 0
\begin{gathered} 4p+3c=(c+2p)(2) \\ 4p+3c=2c+4p \\ 4p+3c-4p=2c+4p-4p \\ 3c\ne2c \\  \end{gathered}

since 3c is not equal to 2c, this means that the expressions are not equal

You have been hired as a marketing consultant to Johannesburg Burger Supply, Inc., and you wish to come up with a unit price for
kotegsom [21]

Answer:

q(p)= -3000p+12000

Step-by-step explanation:

For the function to be linear,

q(p)= mp + c

where

q(p): number of hamburgers sold

p: price per hamburger

m: gradient of the function

c: constant of the function

q(p)=6000 when p=2

6000=2m+c .................... equation I

0=4m+c

c=-4m........................ equation II

Substitute value of c in equation I

6000=2m-4m

m= -3000

c=12000

q(p)= -3000p+12000

A retail chain will buy 900 cordless phones if the price is $40 each and 700 if the price is $60. a wholesaler will supply 550 p
Triss [41]

Answer:

The point of equilibrium is (40,900).

Step-by-step explanation:

It is given that the supply and demand functions are linear.

From the given information it is noticed that the demand function passing through the points (40,900) and (60,700). The supply function passing through the points (30,550) and (50,1250).

If a line passing through two points, then the equation of line is

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

The demand function is

y-900=\frac{700-900}{60-40}(x-40)

y-900=-10(x-40)

y-900=-10x+400

y=-10x+1300                    .... (1)

The demand function is y=-10x+1300.

The supply function is

y-550=\frac{1250-550}{50-30}(x-30)

y-550=35(x-30)

y-550=35x-1050

y=35x-500                  .... (2)

The supply function is y=35x-500.

Equilibrium is the point where the demand and supply are equal.

On solving (1) and (2), we get

x=40

y=900

Therefore the point of equilibrium is (40,900). It means the retailer can buy 900 phones for $40 each and the wholesaler can sale 900 phones for $40.

A family is building a circular fountain in the backyard. The yard is rectangular and measures 14x by 19x and the fountain is go
GuDViN [60]
Remaining yard area = Rectangular yard area- circular fountain area
Rectangular  area = LxW
where 
L= 19x
W= 14x
substitute the variables
                               = 14x x 19 x
                               = 266 x^2
circular fountain area = pi r^2
where r = 6x
subsitute the variable
                                    = 36pi x^2
remaining yard area = 266x^2-36pix^2
                                   =  2x^2(133-18pie)
The answer would be letter D. 2x^2(133-18pie)

Fill the gaps 9,16, ,36,49,
WITCHER [35]
9, 16, __, 36, 49, ___

16 - 9 = 7

49 - 36 = 13

13 - 7 = 6

6 + 7 = 13 

So we will add 7.

16 + 7 = 23

49 + 7 = 56

SO, 9, 16, 23, 36, 49, 56

Hope I helped:P
