How many of the following relations are functions ?

Mathematics
1 answer:
luda_lava [24]2 years ago
7 0

Answer:

3

Step-by-step explanation:

The first set is a function because each x-value has only one given y-value, the second funtion is a function because it is a quadratic equation, the third equation isn't a function because of the point of discontinuity at x=0 because of 1/0 being undefined, and the fourth equation is a linear function.

Answer:

52

Step-by-step explanation:

these equations added together equal 180. so x+2x+24 = 180. add like terms (x+2x=3x) , subtract 24 from both sides, divide by 3 on both sides to get x by itself

Someone please help I’ve been spamming on this and no one has helped yet so please
Gre4nikov [31]

Answer:

The value of x would 12.2.

Step-by-step explanation:

You have to use the pythagorean theorem to solve this.

a = 5.85 (11.7/2)

b = what we are trying to find

c = 13.5

\sqrt{13.5^{2} - 5.85^{2}  } = 12.1666 which rounds to 12.2

I hope this helps, I apologize if it isn't right.

If an hour is 45 years how long is a minute
Ainat [17]
Since one hour = 45 years, one minute should be 1/60th of 45 years because 60 minutes = an hour.

45/60 = 3/4

So one minute would be 3/4 of an hour, or 45 minutes.

Hope this helps!
