1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
2. Wait patiently for a helper to come along.
3. Once someone helps you, say thank you and close the thread with:

   +close
   

4. Feel free to nominate the person for helper of the week in #helper-nominations
5. Do not ping the mods, unless someone is breaking the rules.

Which one

[atomic magnet]

all😭

[shrewd yarrow]

start with the first one

how would you try to solve it?

[atomic magnet]

its a new topic for me sry and our teacher just teached us by showing us a video

volume was low and i couldnt see either

[viscid dragon]

Bruh

[atomic magnet]

😭srry today was our first disscusion

[viscid dragon]

Try making a polynomial

Well nvm

f(x)= 25x+900

[shrewd yarrow]

do you know what a linear equation is?

[viscid dragon]

True

@atomic magnet

Third one is
t(m)= {300 if x≤100
{200+m if x>100

[atomic magnet]

slr, yeah but i forgot about it

[atomic magnet]

sry i was making dinner

[atomic magnet]

is that the answer or is that part of a solution?

could you explain 🙏

[viscid dragon]

What how

[viscid dragon]

Answer

[viscid dragon]

See

The basic connection charge is 900

Which means it has to be always paid

So we start our function as f(x)=300

Now every kWh you use, you'll be charged 25 php

So you'll just add that

[viscid dragon]

Here

So f(x)=300+25x

[shrewd yarrow]

all the questions are in the form of a linear equation f(x) = mx + c, where m is the factor of multiplication and c is the constant

[atomic magnet]

ohhh i get it thx thx

[shrewd yarrow]

in the first question, what would m and c be?

[atomic magnet]

m is 25 and c is 900

[shrewd yarrow]

mb i had class

and yeah that's right

so accordingly, you'll use f(x)= mx + c and get the function

the next part says she has 200kW consumption, assuming it's for the whole month

[shrewd yarrow]

what part of this equation will 200 be?

[atomic magnet]

sorry i was already asleep

i did it last night but im not sure if its right

[shrewd yarrow]

yeah they're all right 👍🏻
