B and D because the domain is the set of X coordinates. (x, y) x is your domain.
2(3x+4y) = 2(24)
6x+8y = 48
Add both the equations
6x + 8y = 48
+ x - 8y = -20
—————————
7x = 28
x = 28/7
x = 4
Plug in this value in the second equation
(4) - 8y = -20
-8y = -24
y = -24/-8
y = 3
Therefore:
x = 4
y = 3
6m+30 is the answer.
Multiply 6 and m and you get 6m.
Multiply 6 and 6 and you get 30.
6m+30
Step-by-step explanation:
x-6y=24
Isolate the Y variable
-6y=-x+24
y=(1/6)x -4
In this case, -4 is the y intercept. Plot a point on the Y-axis (0, -4)
1/6 is the slope. You go up one unit, and then you go right 6 units to plot your next point.

I hope this helps.
solution:
vector N points to the left and up so the components Nx and Ny are negative and positive respectively
then
,
Nx = - N sinθ and Ny = N cosθ
