Using the numbers 5, 8, and 24, create a problem using no more than four operations (addition, subtraction, multiplication, division, square, square root, cube, cube root) where the solution will be an irrational number.
Explain why the result of your operations is an irrational number.
somebody please help me :(
all i know is that this is the equation √(24x5-8)
I need help checking the answer to it.
I think it's 10.583005244
I'm not sure and i need all teh help i can get, thanks
Answer:
Take the square root of a number that is not a perfect square. None of the numbers are perfect squares. After you do that you can do any closed operation you want with the resulting irrational and the two other rationals and you will end up with an irrational.
8*24*√5 is an example.
8+24+√5 is another
5*√8 + 24 is another.
If you take the cube root of any number that isn't a perfect cube you get an irrational, so you could take the cube root of 5 or 24 instead of the square root and do the same thing.

Answer:
y = -2.5/3x
Step-by-step explanation:
[tex]m = \frac{y2-y1}{x2-x1}[/tex]
[tex]m = \frac{7.5-5}{3-6}[/tex]
[tex]m = \frac{2.5}{-3}[/tex] or -0.83333
y = -2.5/3x

1Convert the following equation to slope-intercept formy-3=\frac{1}{8}\left(x+8\right)y−3=8(x+8)
Answer:
y = 8x + 67
Step-by-step explanation:
The equation of a line in slop- intercept form is
y = mx + c
Given
y - 3 = 8(x + 8) ← distribute parenthesis
y - 3 = 8x + 64 ( add 3 to both sides )
y = 8x + 67 ← in slope- intercept form
-1/3(9x-18)+8x simplified. Please awnser my question quick I need it!!
Answer:
5x-6
Step-by-step explanation:
Multiply 9x and 18 with -1/3
-1/3 times 9x is -3x
-1/3 times 18 is -6
So the equation looks like this:
-3x-6+8x
8x plus -3x is 5x
So the answer is: 5x-6

p/q=r/s (solve for q)
Answer:
q=pr/s
Step-by-step explanation:
p/q=r/s multiplication is the inverse of division so they cancel out. and you have to do the same thing to both sides so multiply both sides by "q" it cancels out on the left and stays on the right leaving you with
q=pr/s
