Answer:15
Step-by-step explanation:
Answer:
[f + (g o h)](x) = x² + 6x + 1
Step-by-step explanation:
Given functions are,f(x) = x²
g(x) = 3x + 1
h(x) = 2x
Now we have to find the value of composite function [f + (g o h)](x).
(g o h)(x) = g[h(x)]
= 3(2x) + 1
= 6x + 1
[f + (g o h)](x) = f(x) + (g o h)(x)
= x² + 6x + 1
But Jim got the answer as,
[f + (g o h)](x) = x² + 2(3x + 1)
= x² + 6x + 2
Therefore, Jim's answer was incorrect.
Correct answer will be [f + (g o h)](x) = x² + 6x + 1
X+Y=8 »» X=8-Y
now we can substitute X with 8-Y in the second equation, which was X-Y=2
X-Y=2 »» (8-Y)-Y=2 »» 8-2Y=2 »» 2Y=8-2 »» Y=6/2 »» Y=3
since X=8-Y, and Y=3, so X=8-3=5
X=5 and Y=3
Answer:
7.5!
Step-by-step explanation:
they all add up to 60. divide 60 by 8 and you get 7.5
1/15 is how much further it is
