6x+8y=13 in inverse form and how you got the answer
Answer:
6x + 8y = 13. 8y = 13 - 6x.
y = (13 - 6x) / 8.
f(x) = (13 - 6x) / 8.
x = (13 - 6f-1(x)) / 8.
8x = 13 - 6f-1(x).
6f-1(x) + 8x = 13 S

What is an equation?
A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.
Given that there are two planes to buy tickets.
First plane offers $75 per ticket.
The other plan offers $180 plus $15 per ticket.
Assume that you buy x number of tickets.
According to the first plane, the total cost of x number of tickets is y = $75x.
According to the second plane, the total cost of x number of tickets is y = $180 + 15x
The system of equations is
y = $75x .....(i)
y = $180 + 15x ....(ii)
Using the substitution method solve the equations.
The solution of the equations represents the total cost for the two options is the same.
Putting y = 75x in equation (ii)
75x = 180 + 15x
Subtract 15x from both sides:
75x - 15x = 180
60x = 180
Divide both sides by 60:
x = 3

The price of Stock A at 9 A.M. was $12.81. Since then, the price has been increasing at the rate of $0.11 each hour. At noon the price of Stock B was $13.31. It begins to decrease at the rate of $0.16 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
If the two rates continue, the number of hours when the prices of the two stocks would be the same is equal to 1.85 hours.
How to determine the required number of hours?In order to write a system of algebraic equation to describe this situation, we would assign variables to the price of Stock A and the price of Stock B after a certain number of hours respectively, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the number of hours for the price of Stock A and Stock B to become equal.Let the variable T represent the price of each stockFor the price of Stock A increasing at the rate of $0.11 each hour, an algebraic equation which models it is given by:
T = 12.81 + 0.11x
For the price of Stock A decreasing at the rate of $0.16 each hour, an algebraic equation which models it is given by:
T = 13.31 - 0.16x
Equating the two algebraic equations, we have:
12.81 + 0.11x = 13.31 - 0.16x
0.11x + 0.16x = 13.31 - 12.81
0.27x = 0.5
x = 0.5/0.27
x = 1.85 hours.

What is the area of triangle if sides are 9cm 12cm and 15cm *?
The area of the triangle is 54 square cm.
To find the area of a triangle, we can use Heron's Formula, which states that the area of a triangle is equal to the √ (s * (s-a) * (s-b) * (s-c)), where s is the semi-perimeter of the triangle and a, b, and c are the sides of the triangle.
Step 1: Find the semi-perimeter of the triangle. s = (9 + 12 + 15) / 2 = 21 / 2 = 10.5
Step 2: Substitute the semi-perimeter and the sides of the triangle into Heron's Formula.
Area = √(10.5 × (10.5 - 9) × (10.5 - 12) × (10.5 - 15))
Step 3: Simplify the equation.
Area = √ (10.5 × 1.5 × -1.5 × -4.5)
Step 4: Perform the square root.
Area = √ -94.5 = 54 square cm.
Area = 54 square cm.

The concept given is Sampling, which selects the group that you will actually collect data from in your research. The answer is option B, True; because it is often the case that the individuals who volunteer do not accurately represent the population.
Sampling is the selection of a subset of individualities from within a statistical population to estimate the characteristics of the whole population. Statisticians essay to collect samples that are representative of the population in question.
Frequently, voluntary response samples oversample people who have strong opinions and under-sample people who do not watch important about the content of the check. Therefore consequences from a voluntary response sample aren't as secure as conclusions grounded on an arbitrary sample of the entire population under consideration.
Volunteer slice doesn't induce a representative sample, so, thus, would not be the favored choice of experimenters who were keen to be suitable to generalize their data to the whole population.

What is Isosceles Triangle ?A triangle with two sides that have the same length is said to be isosceles. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.
A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
The hypotenuse is 8 so the equal sides are x lets say.
Now, by Pythagoras Theorem
x^2 + x^2 + = 8^2
x^2 = 64/2
x = [tex]4\sqrt{2}[/tex]

Answer: In order to solve this problem, you should use the Pythagorean theorem. Since FG is perpendicular to OP, and OP and OQ are radii of the same circle, then triangle OFG is a right triangle. Similarly, triangle ORS is also a right triangle. By using the Pythagorean theorem, you can find that:
OF = sqrt(OP^2 + FG^2) = sqrt(19^2 + 40^2) = sqrt(361 + 1600) = sqrt(1961)
and
OS = sqrt(OQ^2 + RS^2) = sqrt(19^2 + 37^2) = sqrt(361 + 1369) = sqrt(1740)
Therefore, the length of the segment connecting the feet of the altitudes is:
OF + OS = sqrt(1961) + sqrt(1740) = 27.2

there?
Please answer both.
The number of points Jim scored is 15 points.
The number of cars given the ratio of car to boat is 140 cars
How to solve algebraic expression?Number of points Kevin has = xNumber of points Jim has = 8 + xTotal points = 22Total points = Number of points Kevin has + Number of points Jim has
22 = x + (8 + x)
22 = x + 8 + x
22 = 2x + 8
22 - 8 = 2x
14 = 2x

= 15 points
Part B:
Boat : car
2 : 5 = 56 : x
2/5 = 56/x
cross product
2 × x = 56 × 5

Answer:
y=2x+3
Step-by-step explanation:
See attached worksheet.
Guidelines are presented on how to both graphically and mathematically solve for the equation.
Graphing: Mark the the two given points and connect them with a ruler to form the line. These same two points may be used to determine the slope, as is shown. The slope is 2. The line intersects the y axis at 3, so the y-intercept is 3. Using the standard form of an equation, the line is y = 2x + 3, as is outlined in the attachment.
The same line is determined mathematically by using the same technique for calculating slope. The value of the y-intercept may be found by using one of the two given points in the equation that has the slope of 2:
y= 2x +b
Enter pont (-1,1), for example, and calculate the value of b. b = 3, (since 1 = 2*(-1)+ b, so b=3).
The equation of this line is y=2x+3
The pressure P of a compressed gas is inversely proportional to the volume V. If there is a pressure of 25 pounds per square inch when the volume of gas is 400 cubic inches, write the equation that can be used to find the pressure when the gas is compressed to 200 cubic inches?
The expression for pressure is P = k/V and pressure is 50 pounds per square inch.
What is the ratio?Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
Given pressure and volume are inversely proportional to each other
P ∝ 1/V
P = k/V
given when pressure p = 25 pounds per square inch
then volume V = 400 cubic inches
25 = k/400
k = 10,000
and when V = 200 cubic inches
then P = k/V
P = 10000/200
P = 50 pounds per square inch
Hence pressure is 50 pounds per square inch.
