The slope of a line that is perpendicular to y = x - 6 means that the slope has to be a negative reciprocal of the original slope
That means the slope of the line that is perpendicular to y = x - 6 is '-1'
Hope that helps!
Answer:
Step-by-step explanation:
For those 2 lines to parallel to each other, then the 2 angles have to be alternate interior and have to be congruent. The value of x that makes them congruent is found by setting the 2 expressions equal to each other and solving for x:
and
so
x = 4.5
Answer:
SP = 627 Rs
Step-by-step explanation:
Percentage loss is calculated as
, then
= 5% = 0.05 ( multiply both sides by 660 )
660 - SP = 33 ( subtract 660 from both sides )
- SP = - 627 ( multiply both sides by - 1 )
SP = 627 Rs
Answer:
The total length of the two cables is 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle ABD
Applying the Pythagoras Theorem

substitute the given values



Remember that
AB=AC ----> because ABC is an isosceles triangle
so
The total length of the two cables is equal to

Answer: -11
Step-by-step explanation:
2(-3) - 5(1) = -11
