The last lines are the final answers, if you need a deeper explanation let me know but I wanted to make sure you understood and got it in time.
Step-by-step explanation:
2(x+4)-3(y+2x)
2x+8-3y-6x
-4x-3y+8
2d+3(4d+2k)-3k
2d+12d+6k-3k
14d+3k
5(4m-2r+7)+4m+3r
20m-10r+35+4m+3r
24m-7r+35
I hope I didn't get anything wrong in a hurry!

Answer:

Step-by-step explanation:
A proportional relationship has equation:

where k is the constant of proportionality.
Since we are looking for a proportional relationship that has a constant of proportionality equal to -10, we have k=-10.
We substitute k=-10 into the equation to get:

Therefore the correct choice is

Answer:
the perimeter is 152, the area is 910
Step-by-step explanation:
perimeter = 20+50+20+10+6+15+6+25
=152
area = (20×50)-(6×15)
= 1000-90
= 910

Answer:
y=1/2 x -2 is the perpendicular line equation
Step-by-step explanation:
y=1/2 x + b
solving for b:
-3=-1 +b
b==- 3+1 = -2
