A bag contains 112 red marbles and 100 green marbles. What percent of the marbles are red?

Step-by-step explanation:

Total marbles are 212

112/212 = 28/53

Approx. 52. 83%

the least common denominator is 40

  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.
