MATH +BASEKETBALL AWESOMENESS!
Directions:1) Sit across from your partner.2) You need: Pencil, Calculator, and A Practice Test3) The game will begin when you are silent.
ANNOUNCEMENTS
• DUE TOMORROW:– Homework packets
• Make sure you’ve graded and fixed all problems• Put in order!
– Extra Credit• Note changes if printed before Wednesday.• (If done, I’ll take as is)
• Tonight’s HW: Fill out Learning Goal Chart & STUDY
– Use study guide as a measure
Instructions• Between the partners, the first one done and correct gets the
point.
• If you are done, help your partner.
• Points from each round determine the FLASH ROUND, but we will have a tally for most points overall at the end.
• We will briefly review answers after each question.
• FYI – FOULS: Off-task = No playing
When you see this guy:
The team member with the most points from the current round will
line up to take a basket. Those who make it (or hit the rim) will go to the board for the FLASH ROUND!
ROUND 1• ADDITION• SUBTRACTION• SCALAR MULTIPLICATION• BASIC DEFINITIONS
• Let A = and B = . Find A + B.
Add elements in the same position
• Let A = and B = . Find 4A - B.
4
=
Add elements in the same position
Let A = and B = .
4X + A = B. Solve for X.
4X + A = B -A -A 4x = B-A
x = (B-A)
Find the product, if possible.
• A = B = Multiply: ROW X COLUMN

THROW YOUR HANDS UP!
• You can win an extra point if you’re the first to raise your hand with the answer to:
Give an example of two matrices that cannot be multiplied together.
What is the equation to find an inverse?
A-1 =
Find the inverse:
A-1 =

• You can win an extra point if you’re the first to raise your hand with the answer to:
DEFINITION OF THE
DETERMINANT
A real number assigned to each matrixFormula: ad-bc
Evaluate the Determinant:
• A =
4 - (- 32) = 36

Those who hit the rim or make it in advance to the FLASH ROUND!!!
Evaluate the determinant:
-3-3 = -6
ROUND 3(start scoring over)
• Solving matrices
Write in Matrix Form:
7x + 2y = 40 6x + 2y = 34
A X = B
THROW YOUR HANDS UP!
• You can win an extra point if you’re the first to raise your hand with the answer to:
If….
A X = B Then…
X = ????
A-1 A-1
X = A-1B
Find A-1
7x + 2y = 406x + 2y = 34
𝐴−1= 114−12 [ 2 −2
−6 7 ]=[ 𝟏 −𝟏−𝟑 𝟕
𝟐 ]
Solve the equation:7x + 2y = 406x + 2y = 34
X = A-1 B =
= 1(40) – 1(34) = 40-34 -3(40) + (34) = -120 + 119
=
(6, -1)
Solve the equation:(Use calc to crunch numbers, but show ALL work)
6x + 8y = 102 -2y = -12 A X = B
X = A-1 B
(1/6)(102) + (2/3)(-12) = 17 -8(0)(102) – (1/2)(-12) = 0 +6
(9, -6)
Solve using your calculator:
5x + 6y + 5z = 59 9x - 2y + 2z = -2 3x - 2y + 3z = -15
Enter in calc: A-1 B = (2, 9, -1)

Those who hit the rim or make it in advance to the FLASH ROUND!!!
FLASH ROUND:
• Solve using your calculator:2x - 2z = 12
2y - 2z = 125x + 2y + 7z = 14
Enter in calc: A-1 B = (4, 4, -2)
