Below are the supply and demand equations for umbrellas in a certain market. in these equations, p represents price, d represent
timurjin [86]

The value of price (p) at a point of equilibrium is 13.4. Then the correct option is C.

<h3>What is the linear system?</h3>

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

The equation of the demand (D) and supply (S) is given below.

\rm D = -\dfrac{4}{3}p +22\\\\S \ = 3p -36

Where p is price.

At equilibrium, we have

D = S

Then

\begin{aligned} \dfrac{4}{3}p +22 &=  3p -36\\\\3p + \dfrac{4}{3} p &= 36 + 22\\\\\dfrac{13}{3}p &= 58\\\\p &= 13.38 \approx 13.4 \end{aligned}

More about the linear system link is given below.

The speedometer in Henry's car is broken. The function y = |x - 8| represents the difference y between the car's actual speed x
Alekssandra [29.7K]

The interpretation of the function is that the difference y between the car's actual speed x and the displayed speed is 8

<h3>How to describe the translation. </h3>

The function is given as:

y = |x - 8|

The above function is an absolute function.

And the parent function of an absolute function is

y = |x|

When a function is translated right by h units, the new function is y = |x - h|

This means that the translation is a translation to the right by 8 units

See attachment for the graph the function.

<h3>Interpret the function and the translation in terms of the context of the situation.</h3>

The function is given as:

y = |x - 8|

This represents the difference y between the car's actual speed x and the displayed speed.

So, the interpretation of the function is that the difference y between the car's actual speed x and the displayed speed is 8

2x+3y= -18 on the graph
enot [183]

Answer:

graph two points at the coordinates (-6, 0) and the coordinates (-8, 3), and make a line through them.

Step-by-step explanation:

First simplify. 2x+3y= -18.,   -----------> 3y= -2x -18., ---------> y= -2/3x -6

To graph this you would first go to the coordinates (-6, 0) and put a point there. Next, you would go to the coordinates (-8, 3) and put a point there. Then make a line and you are done. That should be right.

In winter, the price of apples suddenly went up by $0.75 per pound. Sam bought 3 pounds of apples at the new price for a total o
Vilka [71]

Answer:

look down

Step-by-step explanation:

sam bought 3 pounds so 0.75 multiplied with 3 is 2.25 then we subtract 5.88 by 2.25 to get the original price for 3 pounds which is 3.63. Last step we divide 3.63 by 3 to get the original price for 1 pound and the answer should be 1.21 per pound.

The final equation should be $5.88- $2.25÷3= $1.21
