Find y when X=15 , if y =6 when x=30

3

Step-by-step explanation:

One way is that 30/6 should equal to 15/k. K is the variable. You can do 30/6(5) which means that whatever k equals, the final answer should be 5. So you can do 15/3, which will equal 5 too. So you'll know that they're identical which means that it is correct.

Another way is to see that 15 is half of 30, so it means the answer should be half of 6. 3!

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
