Answer:
happy new year
Step-by-step explanation:
i am your biggest fan I am your teacher you fill
5i because it is a imaginary number.
we know that
The formula to calculate the slope between two points is equal to

we have

Step 1
<u>Find the slope GH</u>

substitute in the formula



Step 2
<u>Find the slope HJ</u>

substitute in the formula



Step 3
<u>Find the slope JG</u>

substitute in the formula



Step 4
Verify if triangle GHJ is a right triangle
we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so

compare slope GH with slope JG
we have


-----> side GH and side JG are perpendicular
The triangle GHJ is a right triangle
The answer in the attached figure
A.) Plan A: 40+40=0.80$
Plan B: 50+38=0.88$
Plan B offers the better deal
B.) Plan A: 40+(40·3)=1.60$
Plan B: 50+(38·3)=1.64$
Plan B offers the better deal
C.) Plan A: 40+(40·5)=2.40$
Plan B: 50+(38·5)=2.40$
They offer the same?
D.) Plan A: 40+(40·6)=2.80+.35=3.15$
Plan B: 50+(38·6)=2.78+.31=3.09$
This one confuses me..
