To do a net drawing you have to cut the object so you can display all its sides in 2D.
An orthographic drawing is 3D object drawn in 2D from 3 points of view: front, left/right and top.
An isometric drawing is 3D object displayed in 2D by rotating it 45 degrees to left/right and 45 degrees upward/downward.

So the correct answers are:
A - net, B - orthographic, C & D - isometric.

Solve the system: 4x – 3y = -21 X=-y-14

Liula [17]

Answer:

The solution for the system of equations is

x=2,y=−2

Explanation:

4x−3y=14.....equation (1)

y=−3x+4.....equation (2)

Solving by substitution

Substituting equation 2 in equation 1

4x−3⋅(−3x+4)=14

4x+9x−12=14

13x=14+12

13x=26

x=2

Finding y by substituting x in equation 1

4x−3y=14

4⋅2−3y=14

8−3y=14

8−14=3y

3y=−6

y=−2
