Answer:
f( g(x)) = 18 *x*x + 6
g( f(x)) = 6xx + 18
Step-by-step explanation:
we want f (g(x)) and g( f(x))
f = 2xx + 6 g = 3x
f( g(x)) = 2 *(3x)*(3x) + 6 = 18 *x*x + 6
g( f(x)) = 3*(2 xx + 6 ) = 6xx + 18
Answer:
Solution to system is
x = 6 and y= 4
S.set={6,4}
Step-by-step explanation:
The given equations are
x + 3y = 18 ................(i)
x + 2y=14 .................(ii)
Subtracting both equation
(x+3y)-(x+2y)=18-14
x+3y-x-2y = 4
y = 4
put the value of y in equation (i)
the equation becomes
x + 3(4) = 18
x + 12 = 18
subtracting 12 from both sides
x + 12 -12 = 18-12
x =6
Solution to system is
x = 6 and y= 4
S.set={6,4}
