1. OPENING PRAYER

2. ATTENDANCE CHECK

3. HAPPY H R ENGAGED E O REMEMBER, HERO ! R ESPECTFUL O UTSTANDING

4. 1. Spin the wheel to choose a student . 2. Reveal the equation to the class. 3. The chosen student will paste the given equation to proper column (LINEAR or NONLINEAR ). 4. Keep spinning until all names are called and the equations are on correct column.

5. 1.) WHEEL OF FORTUNE: LINEAR OR NONLINEAR 2.) 3.) 4.) 5.)

6. 6.) WHEEL OF FORTUNE: LINEAR OR NONLINEAR 7.) 8.) 9.) 10.)

7. 11.) WHEEL OF FORTUNE: LINEAR OR NONLINEAR 12.) 13.) 14.) 15.)

8. 16.) WHEEL OF FORTUNE: LINEAR OR NONLINEAR 17.) 18.) 19.) 20.)

9. •Square root → number that multiplies by itself once •Cube root → number that multiplies by itself 3 times •Fourth root → number that multiplies by itself 4 times REMINDER: 3 4

10. 1. Divide class into 3 groups. 2. Each group will send a representative for each round. 3. Teacher shows a root problem on the television. 4. One player per team races to write the correct root on the board. 5. Correct answer = 2 points. 6. Each group has different representative per round. 7. Tally points and announce winner.

21. GUIDE QUESTIONS: How can you illustrate systems of nonlinear equations ? How do you solve systems of nonlinear equations? How can you engage in collaborative problem-solving to reinforce your understanding of systems of nonlinear equations?

22. ELIMINATION METHOD It is a systematic way to REMOVE one variable from a system of nonlinear equations, usually by addition or subtraction, resulting in a simpler equation to solve.

23. PROCESS: 1. Align the terms in a set of equation in order to determine like terms (the same variables and exponents) 2. Eliminate one variable to make one variable left. 3. Eliminate if the same coefficient but opposite in sign.

27. 1. During Eid al-Adha , a Muslim community organizes a Qurban (sacrificial animal sharing) program. The committee buys goats and cows. •Each goat costs ₱5,000 . •Each cow costs ₱10,000 . •The committee spent ₱55,000 in total on the animals. •They also note that the square of the number of goats plus the number of cows equals 13 . How many goats and how many cows did they buy?

28. 2. During the Ligligan Parul (Giant Lantern Festival) in San Fernando, Pampanga, a group of Kapampangan vendors sells Tamales (a traditional rice delicacy) and Bringhe (Kapampangan-style paella). •Each tamales costs ₱50 , and each bringhe costs ₱200 . •The total sales reached ₱1,150 . •The vendor also notices that the square of the number of tamales sold plus the number of bringhe sold is 49 . How many tamales and bringhe were sold?

29. 3. A school’s MTB-MLE club prepared Kapampangan and Tagalog storybooks to distribute among two grade-level reading groups. • Let x be the number of Kapampangan books and y the number of Tagalog books. • The club distributed 13 books in total . •When the teacher tallied for reporting, she recorded that the sum of the squares of the numbers of each type is 85 . How many books of each language were distributed?

30. 01 Projectile Motion (Trajectory) 03 Business Problems (profit vs. cost curves) 02 Engineering (intersection of design curves) How do you think system of nonlinear equations can be useful in real-life?
