Mathematics
1 answer:
julsineya [31]2 years ago

Answer:

No, every relation is not a function.  

Step-by-step explanation:

Every function is a relation because there are two points (x,y) somehow related to each other.

But every relation is not a function

The given ordered pairs are the function

Since, we are getting different value of y for ecah x.

The condition for function is we should get different value of y for each x.

A customer states that she was shorted in change by receiving only 23 cents change from $3.00
Artemon [7]

Answer:

First, I would check and see if she was correct. If she wasnt, I would simply show her why she was incorrect. If I was to accidently short her, I would give her the money and move on with my day. if she refused to leave after showing her that I gave her the correct amount of money, she would probably call for the manager. I'd get the manager, explain what happened, and the annoying customer would most likely get kicked out of the store.

(P.S: sorry if it was a little confusing lol)

Two buses leave towns 1631km apart at the same time and travel toward each other. one bus travels 17 /kmh slower than the other.
Blababa [14]
Suppose one bus travels at x km/h, the second bus is 17 km/h slower so it is x-17
the first bus travels a total of 7x km, the second bus travels 7(x-17)km, together they travel the total distance of 1631 km
7x + 7(x-17) =1631
7x + 7x -119 =1631
14x=1750

x=125
x-17=108

I need help finding the answer , it would also be nice if you could explain it. Thank you
Aleks [24]
Hello!

First you have to find the values that you can

Angles that are across each other are the same

So the one across 80 is 80 and the angle across 70 is 70

You know 4 of the 6 angles

You add these up together

80 + 80 + 70 + 70 = 300

All the angles together make a circle

A circle has a area of 360

So you do 360 - 300 = 60

Since there are 2 angles left you do

60/2 = 30

The answer is 30

Hope this helps!
