The value of x is -2 when f(x) = 0
Step-by-step explanation:
In any function f(x) = y
- x is the input
- y is the output
- If f(x) = 2 x + 3, then f(a) = b means when you substitute x by a the value of y = b
∵ f(x) = x³ + 8
To find value of x when f(x) = 0, substitute f(x) in the equation by
0 and solve the equation to find the value of x
∵ f(x) = 0
∴ 0 = x³ + 8
- Subtract 8 from both sides
∴ -8 = x³
- Take ∛ for both sides
∵ ![\sqrt[3]{x}=x](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%3Dx)
∵ ![\sqrt[3]{-8}=-2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-8%7D%3D-2)
∴ x = -2
The value of x is -2 when f(x) = 0

Answer:
Hypothesis is: Intersection happens at a point
Step-by-step explanation:
A hypothesis in science is a suggested explanation of something that has a consequence or leads to an occurrence. Usually it will be written in the form of an "if and then" statement.
Such statement explains what would occur, or follow if the possibility enunciated in the "if" part of the statement happens.
In this case the hypothesis is that if there is intersection of lines, it has to occur at a point. Therefore the closest to that statement among the options given in the problem is the last one: "Intersection happens at a point"

You can subtract both sides by w then you are left with 3 = 6, which is false equation.
So there is no solution.
Hope this helps.
