He ratio of girls to boys in a a bicycling club was 3 : 5. there were 50 boys. how manytotal members were there in the club

80

Step-by-step explanation:

Given

Girls : Boys ==> 3 : 5

number of boys as a fraction of total members,

Boys = 5/ (3+5) = 5/8

It is given that there were 50 boys.

hence

5/8 ---> represents 50 members (i.e boys)

1/8 ---> represents 50/5 = 10 members

8/8 > represents 10 x 8 = 80 members

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
