Answer:
The slopes are

Therefore, the equations are equations of <u> Perpendicular Lines .</u>
Step-by-step explanation:
Given:
......................Equation ( 1 )
..............Equation ( 2 )
To Find:
Slope of equation 1 = ?
Slope of equation 2 = ?
Solution:
On comparing with slope point form

Where,
m = Slope
c = y-intercept
We get
Step 1.
Slope of equation 1 = m1 = 
Step 2.
Slope of equation 1 = m2 = 
Step 3.
Product of Slopes = m1 × m2 = 
Product of Slopes = m1 × m2 = -1
Which is the condition for Perpendicular Lines
The slopes are

Therefore, the equations are equations of <u> Perpendicular Lines . </u>
Answer:
#7000, #14000 and #28000 respectively
Step-by-step explanation:
#49000 to be shared in 1:2:4
49000 ÷ (1 + 2 + 4) = 49000/7 = #7000
A will get (7000×1) = #7000
B will get (7000×2) = #14000
C will get (7000×4) = #28000
Answer: A)
Explanation: 10-3=7
