The variables y and x have a proportional relationship, and y=9 when x=2. what is the value of y when x=3?

For this case we have that by definition, if the variables "y" and "x" have a proportional relation, andwhen , then:

Now, we want to know the value of the variable "y" when , then:

Clearing "y" we have:

We multiply by "y" on both sides of the equation:

We multiply by 9 on both sides:

We divide by 2 on both sides:

So, when then

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
