Answer: X=0
Step-by-step explanation when there is no slope the x=0. The line would be flat and horizontal.
Answer:
x = 2 + sqrt(2) or x = 2 - sqrt(2) thus B. is your answer
Step-by-step explanation:
Solve for x over the real numbers:
4 x^2 - 16 x + 8 = 0
Hint: | Write the quadratic equation in standard form.
Divide both sides by 4:
x^2 - 4 x + 2 = 0
Hint: | Solve the quadratic equation by completing the square.
Subtract 2 from both sides:
x^2 - 4 x = -2
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 4 to both sides:
x^2 - 4 x + 4 = 2
Hint: | Factor the left-hand side.
Write the left-hand side as a square:
(x - 2)^2 = 2
Hint: | Eliminate the exponent on the left-hand side.
Take the square root of both sides:
x - 2 = sqrt(2) or x - 2 = -sqrt(2)
Hint: | Look at the first equation: Solve for x.
Add 2 to both sides:
x = 2 + sqrt(2) or x - 2 = -sqrt(2)
Hint: | Look at the second equation: Solve for x.
Add 2 to both sides:
Answer: x = 2 + sqrt(2) or x = 2 - sqrt(2)
To find is out put it like this 2 8
5 x
you multiple so 2 times what eduals 8 then you take that and multiply by 5
no not until u know the price of a cd u cant determine the total price
Hey there!
To simplify radical expressions, refer to the conversion of a radical expression to a number with an exponent:
![\sqrt[a]{x} = x^{\frac{1}{a} }](https://tex.z-dn.net/?f=%20%5Csqrt%5Ba%5D%7Bx%7D%20%3D%20%20x%5E%7B%5Cfrac%7B1%7D%7Ba%7D%20%7D%20)
Remember that if you don't see an index, there is an implied "2" that will go where "a" is.
Depending on your problem, you could also cancel a radical by raising the entire expression by the second power (only if your index is 2).
Hope this helped you out! :-)
