Answer:
the equation of the axis of symmetry is
Step-by-step explanation:
Recall that the equation of the axis of symmetry for a parabola with vertical branches like this one, is an equation of a vertical line that passes through the very vertex of the parabola and divides it into its two symmetric branches. Such vertical line would have therefore an expression of the form: , being that constant the very x-coordinate of the vertex.
So we use for that the fact that the x position of the vertex of a parabola of the general form: , is given by:
which in our case becomes:
Then, the equation of the axis of symmetry for this parabola is:
Answer: a and d
Step-by-step explanation:
First of all, we need to make a analysis of each letters:
a. factoring 32 = 2.2.2.2.2 =
then,
16 =
but
in conclusion that, this inequality is correct
b. 27 =
this first situation is equal to
the second situation is:
81 =
and
it's a mistake.
c. factoring 9:
<
it's wrong.
d. factoring 8 =
factoring 32 =
>
This is true.
Finally.. our correct answers is a and d.
