1) in order for two lines to be perpendicular, their gradients must multiply together to get -1
-1/3*b=-1
b=3
5=3(3)+b
5=9+b
b=-4
equation of the line is y=3x-4
2) parallel lines have the same gradient
4=2(-3)+b
4=-6+b
b=10
equation of the line is y=2x-10
use this equation to solve for the surface area.
A=2(w+l+hl +hw)
w stands for width
l stands for length
h stands for height
Answer:
D. The area of the triangle is 9 square feet, because the area of the rectangle is 18 square feet.
Step-by-step explanation:
Answer:
y=36x, I think would be the correct answer
Answer:I think is 18 divided by 6
Step-by-step explanation:
Because they are saying each that is your clue word that means you need to divide.
I hope it helps :)
