Answer:
21
Step-by-step explanation:
Given the following expressions
f(x) = x³-2x
g(x) =-x-2
We are to find (fog)(-5)
fog = f(g(x))
f(g(x)) = f(-x-2)
Replace x with -x-2 in f(x)
f(-x-2) = (-x-2)³-2(-x-2)
f(-x-2) = (-x-2)³+2x+4
fog = (-x-2)³+2x+4
Substitute x = -5 into the result
fog(-5) = (-x-2)³+2x+4
fog(-5) = (-(-5)-2)³+2(-5)+4
fog(-5) = (5-2)³-10+4
fog(-5) = 3³-6
fog(-5) = 27-6
fog(-5) = 21
Hence the required result of the composite function is 21
Answer:
3/10
Step-by-step explanation:
An hour is 60 mins
so the fraction would be 18/60
Then you can divide both numbers by 6 to 3/10
We have 5x-9 = Y= 2x+6
⇒ 5x-9 = 2x+6
⇒ (5x-2x)+ (-9+9) = (2x-2x)+ (6+9)
⇒ 3x= 15
⇒ x=5
Plug x=5 in Y = 5x-9, we have Y= 5*(5)-9
⇒ Y=16
(x,Y)= (5,16)
Hope this would help :))
