D. I’m not sure but try that
Answer:
X=3
Step-by-step explanation:
NOT CERTAIN.
LEFT SIDE 1 = 13 TIMES
RIGHT SIDE 1 = 4
= 13-4= 9
9/3 = 3
Answer:
Step-by-step B. is your answer
explanation:
or
is very easy to graph.
Choose whatever value of
and use the same for
in the same coordinate. Repeat and strike a line through all the points.
Some examples of valid points would be:
,
,
and
.
Then, to graph
you have to look at it in terms of the equation of a line (
) and its parts.
In this case,
and
.
So, you choose any value for
and you solve to find its
counterpart.
I will start with
:

Now, we have a first coordinate:
.
Repeat with a different value:

It gives us the coordinates
.
Plot those into the graph and strike a line through them.
Wherever the two lines in your Cartesian Plane cross, that is the solution for both equations. It should be
.
You can check it by replacing
and
by "3" in both formulas and equating the values of
:

Your solution is worked out and checked to be correct.
PS: I am attaching a picture of the graph, so you can have a visual idea of what it should look like.
