Answer:
2.3
Step-by-step explanation:
Step 1: Divide 30.50 by 5 to get that each necklaces costs 6.1.
Step 2: Subtract 6.1 (cost for 1 necklace) and 3.80 (price of beads)

Answer:
(5,-6)
Step-by-step explanation:
ONE WAY:
If
, then
.
Let's simplify that.
Distribute with
:

Combine the end like terms
:

Use
identity for
:

Combine like terms
and
:

We are given
.
So we have that
.
The vertex happens at
.
Compare
to
to determine
.



Let's plug it in.




So the
coordinate is 5.
Let's find the corresponding
coordinate by evaluating our expression named
at
:




So the ordered pair of the vertex is (5,-6).
ANOTHER WAY:
The vertex form of a quadratic is
where the vertex is
.
Let's put
into this form.
We are given
.
We will need to complete the square.
I like to use the identity
.
So If you add something in, you will have to take it out (and vice versa).





So we have in vertex form
is:
.
The vertex is (3,-6).
So if we are dealing with the function
.
This means we are going to move the vertex of
right 2 units to figure out the vertex of
which puts us at (3+2,-6)=(5,-6).
The
coordinate was not effected here because we were only moving horizontally not up/down.
Answer:
None of these are equivalent
Step-by-step explanation:
36 + 9 = 45
9(4 – 1) = 9* 3 = 27
(4 • 9) + (4 • 2) = 36+ 8 = 44
