Which of these relations is a function? Which number?

Mathematics
1 answer:
PolarNik [594]3 years ago
5 0

Answer:

#1 is the only relation that is a function.

Step-by-step explanation:

The definition of a function is that every x value (within the interval; for continuous functions) has one y value.  This means that one x value CANNOT have two y values and still be a function.  You can use the vertical line test, do this by imagining a vertical line going up and down the graph.  If that line touches two or more points, then that means there are more than 1 y value for at least one of the x values.  That is a quick way to determine if it's a function.  Only #1 passes this test.

A customer placed an order for muffins.The Baker has completed 37.5% of the order after baking 81 muffins. How many muffins did
IceJOKER [234]
81 divided by 37.5 equals 2.16, 2.16 would be equivalent to 1% so to find 100% we simbly multiply 2.16 by 100, 2.16 multiplied by 100 equates to 216, so the Baker is making 216 muffins.

If this is a word problem, put it into your own words in case of getting in trouble.

I hope this helped, have an awesome day!!

Rearrange to make x the subject of 4(x-3)/a=y
IrinaVladis [17]

Answer: x = a*y + 3

Step-by-step explanation:

To make x the subject of the equation, first, we open the bracket

4x - 12/a = y

Then cross multiply:

4x - 12 = a * y ( a*y means the product of the two variables)

Add 12 to both sides of the equation

4x = a*y + 12

Divide both sides by 4 to get the value of x

x = a * y + 12/4

x = a*y + 3

I hope this helps.
