1/18 School HOLIDAY
MLK, Jr. Day
No school for staff or
students.
1/19 Warm Up- Tuesday
Math in everyday life.
Think of a time you, a
family member, or a friend
had to compare the cost of
products.
Choose a thinking map and
fill in descriptions, events,
or sequences.
1/19 Objective
I will recognize that math can be
used in everyday situations. I will
write an essay explaining how I can
apply concepts from algebra to
solve problems in real life.

1/19 Article
Sometimes there are different charges for the same service or product at different places. For example, Bowl-aRama may charge $2.50 per game plus $2.00 for shoe rental whereas Bowling Pinz may charge $2.00 per game
plus $4.00 for shoe rental. A system of linear equations can be used to compare these charges to find the best
cost.
A system of linear equations is a set of two or more linear equations containing two or more variables. A
solution of a system of linear equations with two or more variables is an ordered pair that satisfies each equation
in the system. So, if an ordered pair is a solution, it will make both equations true. We can also view the
solution as where the equations intersect.
We learned that when two lines intersect at a point, there is exactly one solution to the system. Systems with
one solution are called consistent. There can also be inconsistent or coincident systems. An inconsistent
system is a system that has no solution because the lines are parallel. A coincident system is a system that has
an infinite number of solutions because the equations graph the same line.
In our class, we learned you can solve systems of linear equations using the graph, substitution, elimination,
or matrix methods. The best method to use depends on the forms of the given equations and how precise the
solution should be. Another tool we have learned to use in our class is the graphing calculator. The graphing
calculator can help us find the best cost through the graphing or matrix method.
1/19 Prompt
Write a one page essay (no more than 26 lines)
that describes a time you, a family member, or
a friend had to compare the cost of products.
Then describe how you could have used the
graphing calculator to find the best cost.
Describe how to use both the graphing and
matrix methods.
1/20 Warm Up- Wednesday
1/20 Objective

involving zero and negative
exponents.

Introduction:
When shopping for cars, my family
wanted to get the best car for lowest cost. We
shopped at many places and compared features of
the car to the price. To find the best price, we can
use the graphing calculator.
1/20 Review Writing Literacy
Supporting Paragraph 1:
One way to use the graphing calculator
is the matrix method. When using matrix, you
have to line up same features to same features. In
this case, I could align the cost of each car along
with their interest rate. After that, I would input
the information in the graphing calculator under
second matrix. Then I have to get out of matrix
using second quit. The calculator has to be told
which math option to use, so I would go into
second matrix again. This time I would go to the
math options and move up to B:rref(. After that, I
have to name the matrix the calculator needs to
use, so I would go back to second matrix and hit
[A], then enter, enter.

Supporting Paragraph 2:
Another way to use the graphing
calculator is the graphing method. When using
graphing, the calculator will tell you where the
costs intersect. That is the point where your cost
for each car would be equal. When graphing, you
use the y= function on the calculator. You would
put the equations into y1 and y2, then go to graph
to see if the lines cross. If they do, you would
punch in second, trace, 5, then enter, enter, enter.
Graphing shows you a visual of how the costs
intersect.

Conclusion:
In conclusion, comparing prices is
important in getting the most for your money.
The graphing calculator is a tool you can use to
help you manage your money.

Exponents are a
shorthand way to show
how many times a
number, called the base,
is multiplied times itself.
