The equation of the line is y = 1 + 3x and the total cost for 4 hours is $13

<h3>The equation of the line in slope--intercept form</h3>

From the question, we have the following parameters

Cost per hour = $3

Deposit = $1

The equation in​ slope-intercept form for the line is represented as

y = Deposit + Cost per hour * x

Where x is the number of hours a bike is rented and y is the total cost of renting a bike.

Substitute the known values in the above equation

y = 1 + 3x

<h3>The cost for 4 hours</h3>

Here, we have

x = 4

Substitute x = 4 in y = 1 + 3x

y = 1 + 3 x 4

Evaluate

y = 13

Hence, the cost is $13

A supply company manufactures copy machines. The unit cost C (the cost in dollars to make each copy machine) depends on the numb
ArbitrLikvidat [17]

Answer:

  $9327

Step-by-step explanation:

Apparently, the cost function is supposed to be ...

  C(x) = 0.4x^2 -112x +17167

This can be rewritten to vertex form as ...

  C(x) = 0.4(x^2 -280) +17167

  C(x) = 0.4(x -140)^2 +17167 -0.4(19600)

  C(x) = 0.4(x -140)^2 +9327

The vertex of the cost function is ...

  (x, C(x)) = (140, 9327)

The minimum unit cost is $9327.

_____

<em>Comment on the question</em>

You found the number of units that result in minimum cost (140 units), but you have to evaluate C(140) to find the minimum unit cost.

Find the distance between the two points.<br> (-6, -7) and (154, - 43)
Vitek1552 [10]

Answer:

(160, 36)

Step-by-step explanation:

Distance is always positive because, well, you aren't -50 meters away from your house or something. You are just 50 meters away from your house. And 160 is the distance between -6 and 154, because there is one minus and one plus, you add them, because that is how far they are apart, and then-43 and -7 were easy just subtract them.
