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.
notice, the x-coordinate is the same for both points, thus is a vertical line.

Answer:
0.8888888888888
Step-by-step explanation:
Answer:
here ..
length=6cm
breadth=4cm
height=5cm
<em>we </em><em>know</em><em> </em><em>that,</em>
Total Surface Area of Cuboid, (S )= 2 (lb + bh + lh)
=2(6*4+4*5+6*5)
=2(24+20+30)
=2*74
=148
