If x-y=6 and x^2+y^2=24, find x^3-y^3.

Answers

Answer 1

Answer:

162.06

Step-by-step explanation:

sorry i'm not the best an explaining but i'm confident in my answer.

the first thing to do is get rid of the ² in x²+y²=24, we do this by √24 which ≅4.90 (i rounded to the hundreth place)

then we have this

x-y=6

x+y=4.90

I am using the elmination method. To do that you need to get two letters to have the same coefficient (in 4x 4 is the coefficient) with oposite signs (one possitive one negitive)

In our equation here we see that the same coefficient is 0, and there is oposite signs for y. Therefore we can add the two equations and get

2x=10.9 (the y cancels out)

now we have a simple equation and all that is left is to solve it

10.9/2=5.45

x=5.45

Now we need to find y we do that by pluging the x value into one of the equations I choose the first one becasue its easiest.

(5.45)-y=6  

y= - .55

now that we have both x and y plug them into the final equation (5.45)³-(-.55)³= 161.89-(-.17) =162.06

Therefore x³-y³≅162.06!

Because for the first problem you would have to simplify 8 divided by 2 into 4  in which  12 - 4 = 8 then you would have to simplify 12 - 4 to 8 which 8 = 8

Because  for the second problem you would have to simplify 12 - 8 to 4 which  4 divided by 2 = 2 then you would have to simplify 4 divided by 2 to 2 which 2 = 2

There are parentheses which if there weren't you would get a different answer

Which would be used to solve this equation? Check all that apply.

subtracting 3 from both sides of the equation
multiplying both sides of the equation by 3
dividing both sides of the equation by 3
substituting 4 for p to check the solution
substituting 36 for p to check the solution

Answers

Answer:

1 3 4

Step-by-step explanation:

umm i suck at explaining sorry

Answer: Multiplying both sides of the equation by 3

substituting 36 for p to check the solution

Step-by-step explanation: To undo the division of p by 3, one multiplies by the inverse of 1/3. That is, one multiplies by 3.

Then you have 3(p/3) = 3(12)

p = 36 simplify

To check this work, you can substitute 36 for p:

36/3 = 12 true statement So, the solution process is multiply both sides of the equation by 3 substitute 36 for p to check the work

A farmer had 22.75 bushels of corn. He sold 12 2/5 bushels at the market. His three friends bought the remaining bushels of corn. If each person bought the same amount, how many bushels did each friend purchase?

Answers

Answer:

Each friend bought 3.45 bushels of corn.

Step-by-step explanation:

12 2/5 as a decimal is 12.40. You do 22.75 minus 12.40, which gives you 10.35. Next you do 10.35 divided by 3, which gives you your final answer of 3.45.

if you reflect any shape across the x-axis and then rotate it 90 degrees clockwise about the origin, do you get the same results as if you reflect it across the y-axis and then rotate it 90 degress counterclockwise about the origin? what does this mean?

Answers

Yes, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise direction around the origin to achieve the same results as a shape reflected across the y-axis and rotated in a counterclockwise direction. This implies that these two transformational sequences are similar.

What is reflection in Mathematics?

A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.
