Answer:
a) 5s + 10a = 4500
s+a = 700
b) $2500
c) $1000
Step-by-step explanation:
a) Let students = s and adult = a
5s + 10a = 4500 -------1
s+a = 700 -------2
Using elimination metthod
Multiply eqn 2 by 5
5s + 10a = 4500
5s + 5a = 3500
Subtracting
5a = 1000
a =200
s = 700- 300= 500
b) if both tickets sell for $10 each
200*10 + 500*10 = $7000
Extra money that would have been made = 7000- 4500 =$2500
c) if s is $5 and a is $15
Tickets sold = 200*15 + 500*5 =$5500
Extra money made = $5500- $4500
= $1000
Answer:
A) -20
Step-by-step explanation:
distribute the 4y and the -4 to the parentheses
16y^2 -16y+16y-20-16y^2
combine like terms
16y^2-16y^2=0
-16y+16y=0
-20

The area of the hexagon is 678.96
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Remember that the denominator cannot be equal to zero
so
The value of x cannot be equal to x=-2
<em>Simplify the numerator</em>
----> by difference of squares
substitute
simplify
The domain is all real numbers except the value of x=-2
The y-intercept is the point (0,-6) ---> value of y when the value of x is equal to zero)
The x-intercept is the point (2,0) ---> value of x when the value of y is equal to zero)
therefore
The graph in the attached figure
