Answer:

The equation of demand function is

y=-\frac{1}{2000}x+29

Step-by-step explanation:

We have two point demand function

(38000,10) and (42000,8)

Here x_1=38,000, y_1=10, x_2=42000, y_2=8

The slope of the demand function line is

=\frac{y_2-y_1}{x_2-x_1}

=\frac{8-10}{42000-38000}

=\frac{-2}{4000}

=-\frac{1}{2000}

The equation of demand function is

y-y_1=m(x-x_1)

\Rightarrow (y-10)=-\frac{1}{2000}(x-38000)

\Rightarrow y-10=-\frac{1}{2000}x+\frac{38000}{2000}

\Rightarrow y=-\frac{1}{2000}x+19+10

\Rightarrow y=-\frac{1}{2000}x+29

Let the amount Tom does = x

Then Larissa’s time would be 3x( 3 times the amount of Tom)

And Neal would also be 3x

The total of the 3 is 84 hours so as an equation you have:

X + 3x + 3x = 84

Combine like terms

7x = 84

Divide both sides by 7

X = 84/7

X = 12 hours

Tom = x, so Tom exercised for 12 hours.

Maria and Katy each have a piece of string. When they put the two pieces of string together end to end, the total length is 84in
Serga [27]

Answer: the length of Maria's piece of string is 45 inches.

the length of Katy's piece of string is 39 inches

Step-by-step explanation:

Let x represent the length of Maria's piece of string.

Let y represent the length of Katy's piece of string.

When they put the two pieces of string together end to end, the total length is 84inches. This means that

x + y = 84 - - - - - - - - - - - -1

Maria's string is 6 inches longer than Katy's. This means that

x = y + 6

Substituting x = y + 6 into equation 1, it becomes

y + 6 + y = 84

2y + 6 = 84

2y = 84 - 6 = 78

y = 78/2 = 39

x = y + 6 = 39 + 6

x = 45

Answer:

A(...; 7)

x =-1/5

B(8; ...)

y = 48

The slope is 5

Step-by-step explanation:

y−5x=8

A(...; 7)

We know that y=7, we need to find x

7 - 5x = 8

Subtract 7 from each side

7-7 -5x = 8-7

-5x =1

Divide by -5

-5x/-5 = 1/-5

x =-1/5

B(8; ...)

We know x = 8 we need to find y

y−5x=8

y - 5(8) = 8

y - 40 =8

Add 40 to each side

y-40+40 = 8+40

y = 48

Now we need to find the slope

y - 5x =8

Add 5x to each side

y -5x+5x = 5x+8

y = 5x+8

This is in the form y = mx+b  where m is the slope

The slope is 5
