Table:

Mathematics
1 answer:
Fynjy0 [20]3 years ago
3 0

Answer:

2) Yes, each x-coordinate is only used once.

3) {1,2,3,4}

4) {25,45,60,70}

5) (3,60)

6) No because (4,7) and (4,25) share the same x-coordinate.

Step-by-step explanation:

A relation is a function if there is no more than one y-value assigned to an x.

Any x used can only be used once in an order pair.

You that here.

(1,25)

(2,45)

(3,60)

(4,70)

So basically because all of the x-coordinates are different, this is a function.

The domain is the x-coordinate of each pair (the first of each pair):

{1,2,3,4}.

The range is the y-coordinate of each pair (the second number of each pair):

{25,45,60,70}.

One ordered pair that I see in the table is (3,60). There are 3 others you can choose and I named them above.

{(4,10),(3,15),(1,5),(2,25),(4,25)} is not a function because there are more than one pairs with the same x-coordinate,4.

Answer:

4. $130.50

Step-by-step explanation:

Sorry, but I only know for no.4 which is $130.50.

Explanation: 18 hours is 20 percent more than 15 hours.


So all we have to do is multiply 1.2 to 108.75, since multiplying 1.2 is the equivalent to 20 percent.

Which then is why I get the answer of $130.50.

13s - r^2; if r = 9 and s = 6
FromTheMoon [43]

Answer:

27

Step-by-step explanation:

r = 9

s = 6

r^2

= r x r

= 9 x 9

= 81

13s

= 13 x 6

= 108

13s - r^2

= 108 - 81

= 27
