Question

Please hellp medal and fan given Match each system of linear equations with the quadrant in which the solution lies.
3x – 2y = 10
5x + 3y = 4

3x + 2y = 14
x – 3y = –10

x + 2y = 8
4x + 6y =22

2x + 3y = –12
4x – 2y = –2

A) III

B) I

C) IV

D) II

Answer 1

Answer 2

@OOOPS

Answer 3

What is it Sin or Cos??

Answer 4

you have to find the solution then find out which quadrent its in

Answer 5

yes I know but the solution consist of the 360 circle 2pi /(1)pi where you have the circle of the Sin and Cos

Answer 6

When you know that you will find the quadrents

Answer 7

@zeryoung it doesn't relate to sin or cos

Answer 8

zert your overthinking it its 8th grade math

Answer 9

ow ok

Answer 10

sry I'm way out of that

Answer 11

Finding solution by eliminate or substitute, you will get the answer, then consider whether that solution is in which quadrant.

Answer 12

ow ok I do know now what you mean

Answer 13

hurry please i have 50 questions

Answer 14

3x -2y =10
5x+3y =4
times the first equation by 3 and the second equation by 2, you get
9x-6y =30
10x+6y =8
add them together, you have 19x = 38 --> x = 2 , then replace back to one of the original problem to get y
I choose 5x +3y = 4
replace x =2, I get 10 +3y = 4 --> y = -2
therefore the solution is x= 2, y =-2
You can see x >0, y<0--> the solution is in quadrant 4
@mathmagic101 imitate the steps to solve the leftover

Answer 15

ok th thanks so much

Answer 16

i already fanned you though
