If the average of 12 numbers is 14 and the average of 4 of those numbers is 18, what is the average of the other eight numbers?

(8 + X + Y)/3 = 12

multiply both sides of the equation by 3 to get 8 + X + Y = 36

subtract 8 from both sides of the equation to get X + Y = 28

So, the sum of the 2 missing numbers is 28

a ruler? idk

step-by-step explanation:

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
