Answer:
Option 1, 2 and 4
Step-by-step explanation:
3x-4y-8= 12
3x-4y= 12+8 (bring constants to 1 side)
3x-4y= 20 (simplify)
For a point to be a solution of the above equation, substitute the x and y coordinates into 3x-4y and see if it equals to 20.
Option 1: (0, -5)
3(0)-4(-5)= 20
This is correct
2) (4, -2)
3(4)-4(-2)=20
This is correct
3) (8,2)
3(8)-4(2)= 16
This is incorrect.
4) (-16, -17)
3(-16)-4(-17)= 20
This is correct.
5) (-1, -8)
3(-1)-4(-8)= 29
This is incorrect.
6) (-40, -34)
3(-40)-4(-34)= 16
This is incorrect.
Answer:
Explanation below
Step-by-step explanation:
(3+4)= 7
7+2 = 9
-(3-4) (Invisible one)
-3+4 add to the 9
10
10+2= 12
12-4=8
8×4 =32
Sorry if this seems a bit confusing, but its quite hard to show the process without paper.
Hope this helps! :)
