Answer:
10 presents
Step-by-step explanation:
3 x 5 = 15, and 2 x 5 =10
10! because 3 to get 15 is 5 and 2×5 is 10
-3
9
f(x) = - 3x + 4
Given
9x + 3y = 12
We require to rearrange expressing y in terms of x
Subtract 9x from both sides
3y = - 9x + 12 ( divide all terms by 3 )
y = - 3x + 4
Expressed in functional notation by replacing y by f(x), that is
