Answer:
(x+8)^2=63
Step-by-step explanation:
U got 22 riders....each has 1 saddle....so u got 22 saddles...each saddle has 2 saddle bags....so u have 22(2) = 44 saddle bags...each saddle bag has 3 water bottles....so 44(3) = 132 water bottles
Answer:
x=2, y=6
Step-by-step explanation:
y=10-2x
x=y-4
substitute x
y=10-2(y-4)
y=10-2y+8
Add 2y to each side
3y=10+8=18
y=6
x=y-4
x=6-4=2
x=2
All you do is multiply 300*.27=

As far a domain, you only care about the denominator and radicals.
f(x) = 2 - √x is the denominator, so it can't be 0.
Also x is under a radical, so x can't be negative.
Set the denominator equal to 0 to find the excluded values.
2 - √x = 0
-√x = -2
√x = 2
x = 4, so 4 is an excluded value
The domain is all real numbers greater than or equal to 0, except 4.
[0, 4) U (4, ∞)
0 ≤ x < 4 U x > 4
