Solve the system of equations.
x + 3y = -1
2x + 2y = 6
Answer:
y= -2
x = 5
Step-by-step explanation:
Multiply the top equation by 2 to get
2x + 6y = -2
then subtract the bottom equation by the new equation to get
2x + 6y = -2
--------------------
2x + 2y = 6
which is
4y = -8
y = -2
If y = -2
Then plug -2 into y in the top equation to get x + 3(-2) = -1 and simplify which is
x + (-6) and add 6 to both sides to get x = -1 + 6
which is x = 5
A 6000-seat theater has tickets for sale at $26 and $40. How many tickets should be sold at each price for a sellout performance to generate a total revenue of $185,400?
Answer:
x = number of tickets sold for $26 = 3900 tickets
y = number of tickets sold for $40 = 2100 tickets
Step-by-step explanation:
A 6000-seat theater has tickets for sale at $26 and $40. How many tickets should be sold at each price for a sellout performance to generate a total revenue of $185,400?
Let
x = number of tickets sold for $26
y = number of tickets sold for $40
x + y = 6000
x = 6000 - y
$26 × x + $40 × y= $185, 400
26x + 40y = 185400
Substitute
26(6000 - y) + 40y = 185400
156000 - 26y + 40y = 185400
Collect like terms
- 26y + 40y = 185400 - 156000
14y = 29400
y = 29400/14
y = 2100 tickets
x = 6000 - y
x = 6000 - 2100
x = 3900 tickets
Hence
x = number of tickets sold for $26 = 3900 tickets
y = number of tickets sold for $40 = 2100 tickets
The price of a new computer is $1,449 at your local store. This is 18% less than what it costs at the Brownstone Mall. How much should it cost at the Brownstone Mall?
Given:
Price of new computer at local store = $1,449
This is 18% less than what it costs at the Brownstone Mall.
To find:
The cost of new computer at the Brownstone Mall.
Solution:
Let x be the cost of new computer at the Brownstone Mall.
According to the question,
[tex]x-18\%\text{ of }x=1449[/tex]
[tex]x-\dfrac{18}{100}x=1449[/tex]
[tex]x-0.18x=1449[/tex]
[tex]0.82x=1449[/tex]
Divide both sides by 0.82.
[tex]x=\dfrac{1449}{0.82}[/tex]
[tex]x=1767.07317[/tex]
[tex]x\approx 1767.07[/tex]
Therefore, the cost of new computer at the Brownstone Mall is $1767.07.

A bus traveled on a level road for 2 hours at an average speed 20 miles per hour faster than it traveled on a winding road. The time spent on the winding road was 4 hours. Find the average speed on level road of the entire trip was 310 miles
Answer:
The average speed on level road is 65 mph
Step-by-step explanation:
Let the speed on the winding road be x mph
So the speed on the straight road will be x +20 mph
Mathematically, distance = speed * time
Distance on level road will be;
(x + 20)2
Distance on winding road will be;
x* 4 = 4x
Thus, we have;
2(x + 20) + 4x = 310
2x + 40 + 4x = 310
6x + 40 = 310
6x = 310 - 40
6x = 270
x = 270/6
x = 45 mph
The average speed on the level road is x + 20
That will be 45 + 20 = 65 mph

Suppose a population grows according to a logistic model with initial population 1000 and carrying capacity 10,000. If the population grows to 2500 after one year, what will the population be after another three years?
Answer:
7500
Step-by-step explanation:
1 year= 2500
3 years= x
So we got
2500 × 3 = 7500
The population after another three years will be 15,625.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
Assume a populace becomes as per a strategic model with starting populace of 1,000 and conveying limit of 10,000.
If the population grows to 2500 after one year. Then the increasing factor is given as,
b = 2,500 / 1,000
b = 2.5
Then the equation is given as,
y = 1,000 × (2.5)ˣ
Then the population after another three years will be given as,
y = 1,000 × (2.5)³
y = 1,000 × 15.625
y = 15,625
The population after another three years will be 15,625.
