(20, -12)
(12, -12)
(-6, -12)
(-12, 12)
Answers
Answer:
(5, -12)
Step-by-step explanation:
Put -12 in the equation for y and solve for x:
-12 = -3x +3
4 = x -1 . . . . . . . . divide by -3
5 = x . . . . . . . . . add 1
The solution to the system shown here is ...
(x, y) = (5, -12)

In this case point A is located at (0,-4) because it is ) on the x-axis and -4 on the y-axis. point B is located at (-8,-7) because it is -8 on the x-axis and -7 on the y-axis.
Can you subtract closed polynomials
Answers
Answer:
Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials.

A motorboat travels 9 miles downstream (with the current) in 30 minutes. The return trip upstream (against the current) takes 90 minutesWhich system of equations can be used to find x, the speed of the boat in miles per hour, and y, the speed of the current in miles per hour? Recall the formula d = rt..
Answers
Answer:
Option B
Step-by-step explanation:
When moving with the current, the speeds of the boat and current will add up. The first situation can then be represented by:
9 = 0.5(x + y)
While opposing the current, the speeds will be subtracted. Forming:
9 = 1.5(x - y)
The second option contains this equation system, so it is correct.

Consider the equation, 3x+4y=12.
Write the equation in slope-intercept form.
Identify the y-intercept.
Identify the slope.
Answers
The equation in slope-intercept form is y = -3x/4 + 3.
The y-intercept is 3.
The slope is -3/4.
What is the slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + b
Where:
m is the slope or rate of change.x and y are the points.b is the y-intercept or initial value.Based on the information provided about this line, a linear equation that models it is given by;
y = mx + b
3x + 4y = 12
By making y the subject of formula, we have the following:
4y = -3x + 12
4y/4 = -3x/4 + 12/4
y = -3x/4 + 3
Therefore, the y-intercept is 3 and the slope is -3/4.

Luis drank 12 gallons of juice from the carton how many quarts of juice did Luis drink
Answers
the formula to get that answer is multiply the volume value by 4.
Luis drank 48 quarts of juice. This is calculated by multiplying the known quantity of 12 gallons by the conversion factor of 4 quarts per gallon.
Explanation:This question involves a unit conversion from gallons to quarts. In the US customary measurement system, we know that 1 gallon is equal to 4 quarts. Since Luis drank 12 gallons of juice, to find out how many quarts Luis drank we would perform the following multiplication:
12 gallons x 4 quarts/gallon = 48 quarts
Therefore, Luis drank 48 quarts of juice.

Mrs. Henson's rectangular afghan is 2 feet
longer than it is wide. If the afghan has an
area of 24 square feet, what is its width?
(Remember, the area of a rectangle is its
length times its width.)
Answers
Answer:
The width is 4
Step-by-step explanation:
If the length is 6 feet, minus 2 will be 4. Six times 4 is 24, which is the area of the afghan rug. We are multiplying 6 and 4 because it is length times width in rectangle area.
Mrs. Henson's rectangular afghan width will be 4 feet
Area of a rectangleIt is the product of its length and width
How to solve this problem?
Let, x be width of rectangular afghanGiven,Length of afghan is 2 feet more than its width
∴ l = x+2
Area of rectangular afghan = 24 square feet
Now,Area of rectangular afghan = lw
[tex]24=x(x+2)\\24=x^{2} +2x\\x^{2} +2x-24=0\\x^{2} -4x+6x-24=0\\(x-4)(x+6)=0\\x=4 or -6[/tex]
Since width can not be in negative[tex]x=4feet[/tex]
So the width of rectangular afghan will be 4 feet

One side of a rectangle is three times the other. Find the longer side if the perimeter is
29
Answers
Answer:
Answer: 10.875
Step-by-step explanation:
Let the short side be x.
Then the long side is 3x.
There are two opposite sides of each length, so the perimeter is
3x + 3x + x + x = 8x
The perimeter is 29, so we get the equation
8x = 29
Solve for x by dividing both sides by 8.
x = 29/8
x = 3.625
The longer side is 3x.
3x = 3(3.625) = 10.875
Answer: 10.875
Answer:
Answer:10.875
Step-by-step explanation:
Let the short side be x.
Then the long side is 3x.
There are two opposite sides of each length, so the perimeter is
3x + 3x + x + x = 8x
The perimeter is 29, so we get the equation
8x = 29
Solve for x by dividing both sides by 8.
x = 29/8
x = 3.625
The longer side is 3x.
3x = 3(3.625) = 10.875

The population density of Australia/Oceania is calculated by dividing the total population (3.11 × 107 people) by the total area (7.69 × 106 square kilometers), which results in a density of approximately 4.04 people per square kilometer.
Explanation:To calculate the population density of Australia/Oceania, we need to divide the total population by the total area. The area of Australia/Oceania is approximately 7.69 × 106 square kilometers, and the population is approximately 3.11 × 107 people.
The calculation for population density is:
Population Density = Total Population / Total Area
So:
Population Density = 3.11 × 107 people / 7.69 × 106 square kilometers
This results in a population density of
Population Density = 4.04363 people per square kilometer (unrounded)
Rounded to the nearest hundredth, the population density is approximately 4.04 people per square kilometer.

You would then divide the end value by the original value.

To find what percentage the stock declined by, you would subtract.

Which graph represents the equation y = --3x – 1?
Answers
Answer:
Step-by-step explanation:
The equation y = -3x - 1 represents a straight line with a slope of -3 and y-intercept of -1. The graph will be a line falling to the right and crossing the y-axis at -1.
Explanation:The question asks which graph represents the equation y = -3x - 1. This is a linear equation, where the coefficient of 'x', -3 here, gives us the slope of the line, and the constant, -1 here, gives us the y-intercept. A slope of -3 means for each step of 1 increase in x, the value of y decreases by 3. The y-intercept is the point where the line intersects with the y-axis, in this case at y = -1.
A graph representing this equation will be a straight line with a slope of -3 (indicating the line falls as we move along the positive x-axis) and will cut the y-axis at y = -1.
