If point b is halfway between 0 and 1 on a number line and point a is halfway between 0 and point b, what fraction of 1 does point a represent?

So B is halfway between 0 and 1. What's half of 1? 1/2.

A is halfway between 0 and B. What's half of 1/2? 1/4.

So A is 1/4 of 1.

Alternatively -

0 - A - B - - - 1

If each - is an eighth, A is at 2/8, or 1/4

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
