Mr. Robles has two kinds of fruit in his basket. The ratio of apples to oranges in the basket is 3:4.
If there are 9 apples, how many pieces of fruit are in his basket?
OA. 38
OB. 8
OC. 12
OD. 21

answer is "c" - 12

Step-by-step explanation:

apples = 3x ( 3 of x )

orange = 4x (4 of x)

if 3x = 9

x= 9/3= 3

then 4x = 4(3)= 12!!

There may be other ways to solve  this but this is one I guess : )

21 is the answer

Step-by-step explanation:

  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.
