Plug in -1 for x
and you'll get this:
Solve it further and you'll get:
Therefore,
where x = -1
If you have double functions, solve the one in the parentheses first.
in f(g(2)), solve g(2) first.
So, substitute 2 in the function.
g(x) = x^2 - 6x - 7
g(2) = 2^2 - 6(2) - 7 = -15
If you substitute -15 in f(g(2)), it becomes f(-15).
f(x) = x + 8
f(-15) = -15 + 8
f(-15) = -7
The answer for f(g(2)) is -7.
Answer:
answer is below
Step-by-step explanation:
Answer:
21 adults and 139 children
Step-by-step explanation:
x=adult (8$)
y=child (5$)
8x + 5y =863
x+y=160
-x -x (subtract x on both sides)
y= -x + 160
plug that in for y on the other equation
8x + 5(-x + 160) =863
distribute 5 to both
8x + -5x + 800 = 863
combine both x values
3x + 800 = 863
-800 -800 (subtract on both sides)
3x = 63
divide by 3 on both sides
x = 21 adults
now plug x in one of the equations
21 + y = 160
-21 -21
y=139 children
If it’s hit 3 feet the maximum is 3 so it comes all the way up on a graph or whatever and then back down so the answer is 3 hope this helped !!
