Answer:
A1/ ∛m
Step-by-step explanation:
m ^ (-1/3)
this is m to the cubed root in the denominator
1/ ∛m
180/4=45
45 people will cover the expenses
500/4 = 125
45 + 125 = 170
sell 170 tickets and you will cover the expenses plus make 500$
You want to get the x by itself so add 3y to the other side and divide 3y+6 by 1 and you get 3y+6 and divide the 6 by 3 and your answer is 2
We have
f(x) = 1/x+5,
g(x) = 5x+1/x -------> (5x²+1)/x
<span>
1) find the f(g(x))
</span>f(g(x))=(1/(5x²+1)/x) +5---- > (x/(5x²+1)) +5---->(x+5*(5x²+1))/(5x²+1)
(x+25x²+5)/(5x²+1)---------- > (25x²+x+5)/(5x²+1)
f(g(x))= (25x²+x+5)/(5x²+1)--------> is not x
therefore
<span>f(x) and g(x) are not inverses of each other
</span>the domain of the composition f(g(x)) is (-∞,∞)
2) find the g(f(x))
g(f(x))=(5(1/x+5,)²+1)/(1/x+5,)------- > (5/x²)+(10/x)+25+(x/(5x+1))
[5*(5x+1)+10x*(5x+1)+25x²*(5x+1)+x³]/[x²*(5x+1)]
the domain of the composition g(f(x)) is (-∞, -1/5) U (-1/5,0) U (0,∞)
Answer:
x = 5.
Step-by-step explanation:
2x^2 + 1x + 2 = 57
2x^2 + x - 55 = 0
(2x +11)(x - 5) = 0
x = 5.
