Does a vending machine represent a function and why?

1 answer:

4 0

Sure, depending on how the machine is constructed or programmed.

A function can represent any process that takes some input and assigns exactly one output to it. In the case of a simple vending machine, there could one button or sequence of button presses that correspond to the delivery of a certain drink or snack (provided that enough money is fed into the machine first).

A machine that wouldn't qualify as representing a function would be one that consistently offers two or more different drinks.

I need help<br> (Find the slope of the line through the given pair of points)<br> (-7,-18),(4,4)

larisa [96]

Answer:

Step-by-step explanation:

You can find slope using the slope equation : $\frac{y2-y1}{x2-x1}$

Plug in the two points : $\frac{4-(-18)}{4-(-7)}$

Calculate by adding the numbers: $\frac{22}{11}$

Reduce the fraction : 2

The slope is 2

Question:

What is the common denominator of $y+\frac{y-3}{3}$ in the complex fraction $\frac{y+\frac{y-3}{3}}{\frac{5}{y}+\frac{2}{3 y}}$

A) $3 y(y-3)$

B) $y(y-3)$

C) $3y$

D) $3$

Answer:

Option D : 3 is the common denominator

Explanation:

It is given that the complex fraction $\frac{y+\frac{y-3}{3}}{\frac{5}{y}+\frac{2}{3 y}}$

We need to determine the common denominator of $y+\frac{y-3}{3}$ from the complex fraction.

Let us consider the fraction $y+\frac{y-3}{3}$

To find the common denominator, let us take LCM.

Thus, rewriting the above fraction as,

$\frac{y}{1} +\frac{y-3}{3}$$

The LCM can be determined by multiplying the denominators.

Thus, we get,

$1\times3=3$

Thus, the common denominator is 3.

Hence, Option D is the correct answer.

Y=ax with a>1<br><br> im very confused on what to do

Kazeer [188]

Answer:

Step-by-step explanation:

‘a’ in this question is the slope of the line. Slope is (y2-y1)/(x2-x1) for any two points. We can see the line intersects the point (0,0) and (-10/9) so the slope is -10/9 which is less than -1 so

hodyreva [135]

Cole can learn how to play tennis. But if he saved the money, he can save up and get something bigger, or save up for college. There is only so much he can do with a tennis racket except for using it to learn a new sport.
