The slope of this line is undefined as it is a vertical line.
Hope this helps.
Answer:
If x varies directly as y, then x=ky. y=5 and x=2.5 are substituted into x=ky to find k.
2.5=5k
k=2.5/5
k=5.
K =5 is substituted in x=ky to find y where x is 10.
x=5y
10=5y
y=10/2
y=2
Given:
The equation is

To find:
The solution of the given equation.
Solution:
We have,

It can be written as


Multiply both sides by 7.




Divide both sides by 7.


Therefore, the value of z is -2.
Area of circle = pi (d/2)^2
area of semi-circle =0.5* pi (d/2)^2
=0.5* pi (6/2)^2
=14.14
