What is the value of x in the equation 1 / 5 x - 2 / 3 y equals 30, when y equals 15

x=200

Step-by-step explanation: 1/5x-2/3y=30

1. Substitute y for 15: 1/5x-2/3(15)=30

2. Multiply 2/3 by 15 which is 10

3. Add 10 to 30 because of the negative sign before the -2/3

4. 1/5x=40

5. Multiply both sides by 5 to get 1x=200

6. x=200

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

$12. that is my answer.
