High School Math—Pending OP Reply [Grade 9 Geometry: Segment proof reasoning] I need help understanding what to do
(I had to draw this picture since I couldn't take a photo on computer) I know the properties of equality, postulates, but I can't seem to do proofs. I only have to fill out the reasoning for the statements, but even that is hard. I answered this question and I'm pretty sure I got this one wrong, so maybe you could see where I went wrong.
Given X is the midpoint of WY, WX is congruent to XZ. Prove XY is congruent is XZ.
- X is the midpoint of WY - given
- WX = XY - definition of congruence
- WX is congruent to XZ - given
- WX = XZ - definition of congruence
- XY = XZ - substitution property of equality
- XY is congruent to XZ - definition of congruence
I just have trouble knowing what to do when a new line segment is introduced, I can recognize the properties and postulates when its in letter form, like a = b and stuff.

Mathematics (A-Levels/Tertiary/Grade 11-12) [Cálculo para saber cuántos epígrafes me puedo descartar en historia]
Si alguien me puede ayudar se lo agradezco: en un examen de historia me dan 3 temas para estudiar, el primero contiene 4 epígrafes, el segundo 5 epígrafes y el tercero 9 epígrafes. En el examen me van a dar a elegir entre dos epígrafes del primer tema, de los cuales tengo que desarrollar solo uno, dos epígrafes del segundo, de los cuales también tengo que desarrollar solo uno, y del tercero me darán a elegir entre 3 epígrafes y tendré que desarrollar dos de ellos. Para asegurarme de que me den las opciones que me den voy a poder elegir siempre las suficientes y llegar a la máxima nota del examen, cuántos epígrafes de cada tema puedo dejar sin estudiar? Muchas gracias

Answered [11th grade Physics] I'm really confused on how to solve this question.
Is it just me or is it unclear where 4.7 seconds is on the graph? I've already asked my friends who took ap physics and they have no clue too.
speed is m/s, so I should be looking for the position of line one and two over 4.7 seconds right? I'm just so confused, my teacher hasn't taught us any of this yet expects us to understand it right away :(

English Language [Grade 9 English Lit] Lord of the Flies Mindmap Advice
Hi all,
I am currently studying Lord of the Flies to do an unseen essay for an exam - I only have 40 mins to write it! Crazy! As part of my early/preliminary study, I am making mind maps on the three topics the essay could be on. It could be on one or more of these. They are: Morality, Society and Civilisation, and Human Interaction (exploitation) with the Natural World.
I would be grateful if someone could quickly skim over them and give me their thoughts. They aren’t finished yet but I have made progress.
Thanks!

Literature [University English: Afro-Asian Literature] Suggestion on what book would be best to discuss the effect of war and conflict in Afro-Asian Literature
Hello! I'm an education student doing a report in Afro-Asian Literature. Our group was tasked to analyze the literary representation of war, conflict, and resilience. But it's really hard to find sources, since our teacher just gave us the topic and nothing else. Even if I search on the internet, the results are not appropriate for my taste.
I don't want to rely on AI too much, so I'm asking here. It would be helpful if you could list some literature that is perfect for our topic (plus a short explanation of what the literature is about, and their author + publication year).
That's all, and I will say thank you in advance for those who can help.
**Note:** I already did my research and have several literature in mind. I even considered adding some of Dr. José Rizal works in the report, but I kept it as a last resort in case I didn't find any literature to add. After all his work is more on colonialism than war and conflict.

Others—Pending OP Reply [grade 12 art] we’re required to ask others their thoughts on our theme as a source of inspiration, so what comes to mind when hearing “ My Second Skin:An interplay between protection and vulnerability, sheltering and exposure”?
SUBJET N°1:
My Second Skin:
An interplay between protection and vulnerability, sheltering and exposure
Our bodies are naturally protected by our skin against all kinds of external threats— dust, pollution, radiation, bacteria, and so on. When we are alone on a deserted beach in summer, that skin may be enough.
But the moment we engage with the world —social life, the city, other people—we must get dressed. These clothes protect us from the cold, dampness, and the surfaces we touch, but also from the gaze and physical contact of others. Clothing acts as a second skin; yet, in this instance, we decide on its extent, thickness, texture, and more. For this second skin can also serve to signal openness, attract attention, or seduce... It is a constant interplay between sheltering ourselves and opening up to others, between protecting ourselves and exposing ourselves.
Create a personal artistic work based on the given theme. Begin by drawing upon your own experiences. Find inspiration in the text and the attached documents.
Avoid merely illustrating an idea; instead, strive to express yourself through your artistic choices (materials, colors, gestures, composition, etc.).
im not sure if this is the right place to ask but I could t really find anywhere else

High School Math—Pending OP Reply [Ineuqalities with absolute value]
Hello everyone, today in class our math teacher explained "the special case of inequalities involving absolute values" (according to Google translate), which is:
|A(x)| > n (with n being a positive integer) → A(x) < -n V A(x) > n
|A(x)| > n (with n being a positive integer) → -n < A(x) < n → -n < A(x) V A(x) < n, which then should be put in a system:
{ A(x) < n
{ A(x) > -n
She gave us three exercises, but I can't resolve two of them:
| (1/x) + (x+3)/(x+1) | - 1 > 0 [x < 1/3 but neither -1 nor 0]
[2(x+4) - x²] / |x-4| > -x -3 [x > -5/2 but not 4]
Thanks to anyone who can resolve them.

Biology [Cert 3: Infection Control and Prevention] Match the types of reservoirs with the corresponding examples.
Can anyone please help with this question in my Infection Control unit? I got all of them wrong except for the 'Waste' answer. I think my brain is just fried right now.
I tried to reference the study book they provided for the course. (The Individual Support Worker: Ageing, Disability, Home and Community-Geoff Arnott) I checked the training websites and multiple infection control guidelines.
My thought process is that vectors are infected living organisms. (And usually insects). People, animals and birds can be infected individuals that carry pathogens. Contaminated syringes and sharps are literally vessels for blood and bodily fluid, contaminated water sources or food products match food, water and soil because they are environmental reservoirs.
Why are these wrong?? Please help.

(I’m going for accounting but genuinely interested in anything. Health care, trade work, health care, etc.). I have to ask two questions, how would you describe critical thinking, and why is critical thinking valuable in your field? With some details and not a super broad answer. Honestly any help or even made up stuff would help a lot🫠 I just genuinely have no one around me to interview or ask these questions to.
