Answer:
C
Step-by-step explanation:
Power of a power as applied to exponents is the following:
The power of a power is the product of the exponents, or
(x^a)^b = x^(ab)
For example
(5^2)^3=5^(2*3)=5^6=15625
L=16
W=21
Set up a systems of equations:
x=length
y=width
xy=336
x+5=y
Use substitution to solve:
x(x+5)=336
x^2+5x=336
Solve using factoring:
x^2+5x-336=0
(x-16)(x+21)=0
x=16 and x= -21
Since length can't be negative, l=16
To find width, plug length into the first equation:
(16)y=336
y=21
So...
L=16

Answer:
the x is the independent variable so the guests the y is the dependent variable so the cost.
Step-by-step explanation:
because so when there are 100 people there is 4,200 +750 and the cost is 4,950
