The sum of two integers is 8 and their product is -20. What are the integers?

emmasim [6.3K]

Answer:

The answer to your question is

x = -2 and y = 10 or x = 10 and y = -2

Step-by-step explanation:

x + y = 8 (1) from (1) x = 8 - y

xy = - 20 (2)

Solve them by substitution

(8 - y) y = - 20

8y - y² = -20

y² - 8y - 20 = 0

( y - 10) (y + 2) = 0

y - 10 = 0 and y + 2 = 0

y1 = 10 y2 = -2

x1 = 8 - 10 x2 = 8 - -2

x1 = -2 x2 = 10

The amphitheater has two types of tickets available, reserved seats and lawn seats. The maximum capacity of the venue is 20,000

Tema [17]

Let the number of reserved tickets = x

Let the number of lawn seats = y

Constraint functions:

Maximum capacity means $x+y\leq 20000$

For concert to be held $x+y\geq 5000$

$lawn seats\leq reserved$ means $y\leq x$

Objective functions :

Maximum profit equation p = 65x +40y

Intersection points :

(10000,10000) (20000,0)(2500,2500)(5000,0)

p at (10000,10000) = 65(10000) + 40(10000) = $1050000

p at (20000,0) = 65(20000) + 40(0) = $1300000

p at (2500,2500) = 65(2500) + 40(2500) = $262500

p at (5000,0) = 65(5000) + 40(0) = $325000

Hence maximum profit occurs when all 20000 reserved seats are sold and the profit is $1300000

Please find attached the graph of it.
