I will mark you
Nana76 [90]

Answer:

Yes, because the x's do not have more than one y.

Step-by-step explanation:

x      y

0      0

5       10

6       12

10     20

(That's meant to be a table). Looking at the x and y table values, you can see that none of the x's have two y's. So, this relation is a function.

The sum of twice a number and another number is 24. The difference of twice the first number and the other number is 12. Which s
dem82 [27]

Answer:

The system that models the situation is:

\left \{{{2x + y = 24} \atop {2x - y = 12}} \right.

The solution is:

(9, 6)

Step-by-step explanation:

We must write the equations as indicated in the problem.

The sum of twice a number and another number is 24

<em>a number:</em>  x

<em>other number:</em>  y

Then

2x + y = 24

The difference of twice the first number and the other number is 12

<em>first number: </em> x

<em>other number:</em>  y

Then:

2x - y = 12

The system that models the situation is:

\left \{{{2x + y = 24} \atop {2x - y = 12}} \right.

To solve the system we add both equations to find the value of x

2x + y = 24\\\\2x - y = 12

---------------------

4x +0 = 36\\\\x=\frac{36}{4}\\\\x=9

2(9) +y = 24\\\\y=24-18\\\\y=6

The solution is:

(9, 6)
