i hope po na makagawa din kayo ng videos on solving word problems ng equations and inequalities (sa word problem po talaga ako napapatumba HAHAHAH). thank u so much poo! vv helpful po talaga mg vids at tutorials niyo!
good evening po sir. based sa number one question po sir parang mali po eh. Tapos nag search ako kung same ba answer mo sa online. 23 po sagot nila instead of 24. eto po yung solvong nila sir, hindi po to sakin galing. hehe Let Cora's age be 𝑥 and Danilo's age be 2(𝑥−4) since Danilo is twice Cora's age 4 years ago Three years from now, Cora's age will be x+3 and Danilo's age will be 2(x−4)+3 . 3Set up the equation based on the sum of their ages 3 years from now: x+3+2(x−4)+3=47 . Solve the equation to find Cora's current age, x=16 . 5Cora's age 8 years from now will be 16+8=24 .
The expression 2(x - 4) gives Danilo’s age 4 years ago, not his present age. If Cora’s present age is x, then Danilo’s present age should be 2(x - 4) + 4 The new equation would then be x + 3 + 2(x - 4) + 4 + 3 = 47, which gives an answer of x= 15. Adding 8 would give Cora’s future age to be 23.
ang vertex form po kasi ng parabola ay y=a(x-h)^2+k at since may negative sign ang -h (or -20 sa given example), parang magiging positive na yung dating niya kaya sa kanan siya papunta :)
Based sa number ng zeroes. If isa lang ang root ng equation, the function crosses the x axis once. If dalawa, twice siya magpapass. If walang root, di siya magcocross at all.
@@MakiDelosSantos-s7v no, kapag mag tratranspose po tayo, yung original sign ng number/variable ay gagawin nating opposite. Halimbawa, 2x+4=12, since ang 4 and 12 is parehas constant and walang variables (like x/y), ililipat natin yung positive 4 sa kabila or right side. Since positive (+) siya, ang opposite ng positive is negative (-) 4. From 2x+4=12, magiging 2x=12-4, then 2x=8, divide 2 (para makuha value ng "x") x=4.
hello po! currently watching po ako. hindi ko pa po naccheck ’yung ibang vids, math lang po ba ang inooffer niyo for this upcat free review or included din po yung other subtest like science, language proficiency and reading comprehension? thank you so much po!

good evening po sir. based sa number one question po sir parang mali po eh. Tapos nag search ako kung same ba answer mo sa online. 23 po sagot nila instead of 24. eto po yung solvong nila sir, hindi po to sakin galing. hehe
Let Cora's age be 𝑥
and Danilo's age be
2(𝑥−4) since Danilo is twice Cora's age 4 years ago
Three years from now, Cora's age will be
x+3 and Danilo's age will be
2(x−4)+3 .
3Set up the equation based on the sum of their ages 3 years from now:
x+3+2(x−4)+3=47 .
Solve the equation to find Cora's current age,
x=16 .
5Cora's age 8 years from now will be
16+8=24 .
The expression 2(x - 4) gives Danilo’s age 4 years ago, not his present age.
If Cora’s present age is x, then Danilo’s present age should be 2(x - 4) + 4
The new equation would then be
x + 3 + 2(x - 4) + 4 + 3 = 47, which gives an answer of x= 15. Adding 8 would give Cora’s future age to be 23.
Gets na yung confusion. Medyo ambiguous yung pagkasabi sa statement. The problem is intended as “4 years ago, Danilo is twice the age of Cora.”

15:43 question 2
bakit po negative to the right? di po ba kaliwa ay negative tas positive kanan sa cartesian plane?
ang vertex form po kasi ng parabola ay y=a(x-h)^2+k at since may negative sign ang -h (or -20 sa given example), parang magiging positive na yung dating niya kaya sa kanan siya papunta :)
very helpful, hope it gets more recognition
Thank you Po.

Good luck sa exam!
Thank you so much for this!!😄

Paano po nakuha yung 11=9× sa question number 41?
Left side: 2+9
Right side: 15x-6x
UP cutie
hello po, bat po naging 2 instead of 1.75 ang sagot sa #38? thank you po 1:42:53
Infinite sum siya. Hindi lang tumitigil sa 1/4 ang terms. Meron pang 1/8, 1/16, etc.
Pano po naging 33 yung sa number 1 age problem?
Using transposition, 47-7-7=33
thanksss
sa question no. 42 san po kayo nagbase ng ONCES? or pano naging onces? Thanks po

up cutieee
nganong karon pa ko gatuon
Sa question #43 po yung 1.25 po bakit po naging 25% Yung answer, ignore na lang po ba Yung 1.?
A 25% increase means one fourth of the original price is added to itself. So magiging 100% + 25% or 125% or 1.25
If you could make it a little bigger
Kapag mag ttranspost po ba kailangan as long as possible dapat ang magiging answer is positive?
kaya parang either sa left or sa right siya i-transpost
itranspose mo yung mga like terms
for example, pagsamahin mo sa isang side yung mga constant tapos sa kabila yung mga may kasamang variables

Included na lahat ng subjects, watch until part 7!
Hindi po na discuss ang 16-30?
Check out Day 3 for the discussion!
upcat cutie 2025!
saan po galling yung x^2 + 7 sa question number 42 po?
Using synthetic division, the quotient has coefficients 1, 0, 7. This would then become (1)x^2 + (0)x + (7) or (x^2 + 7)
Thank you so much po❤

ano pong lesson yung question number 2?
@@JeimyleiLaus Functions
HAHAHA YUNG ZOOM MEETING SHENANIGANS
what if z is equal to zero? no.14
Based on the context of the problem, z has a cost because A, B, and C can be bought.

Ang slow ko 😓 paano po naging 33 yung 3x?
47-7-7
1:44
pano po naging 33? no.1
47-7= 40
40-7= 33
Wala po bang question no.16 - 30?
Nasa next video namin (Day 3)
not helpful at all, I won't recommend this to anyone
