Answer:
Part 1) The slope of DE is
Part 2) The slope of FG is
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
step 1
Find the slope of DE
we have
D(-a-b,c) and E(0,2c)
substitute in the formula
step 2
Find the slope of FG
we have
F(a+b,c) and G(0,0)
substitute in the formula
Simplify the sign minus
Note The slope of DE is equal to the slope of FG. therefore DE and FG are parallel
Answer:
Step-by-step explanation:
2.) −$180/year
For this you need to know your angles in parallel lines.
3y will equal 87 as they are opposite angles and opposite angles are equal.
So y = 87/3
We can use the knowledge that angles in a straight line (in parallel line diagrams) will add up to 180. Therefore we do 180-87= 93. Now we know 3x=93 because just like the first example they are opposite angles. Now we know x=93/3.
(I didn’t have a calculator on me so you’ll have to work out the final result. Also I recommend looking into angles in parallel lines. I tried my best to explain so I hope you understand the jist of what I was trying to say.)
