Question 1199831
<font color=black size=3>
The given function is  
f(x,y) = 5y+10x


We want to find f(6,2)
Wherever you see 'x', replace it with 6.
Wherever you see 'y', replace it with 2.
Then simplify.


f(x,y) = 5y+10x
f(6,y) = 5y+10*6 ...... replace x with 6
f(6,2) = 5*2+10*6 ...... replace y with 2
f(6,2) = 10+60
f(6,2) = 70



Answer: 70
