Answer:
Step-by-step explanation:
We were given the slope formula;
This line is vertical if the denominator is zero.
That is when 
This implies that;
Justification;
When , then, the line passes through;
and 
The slope now become
The equation of the line is
This implies that;
... This is the equation of a vertical line.
Find difference i.e 100-82=18
if 82 is 100%, what about 18?
(18*100)/82= 21.951 ans
Answer:
A: 71°
Explanation:
The interior angles of a triangle must always equal 180°.
We have two of the angles, and if we add them up and subtract it from 180°, we can get the missing angle.
49+60+x=180
Add 49 and 60
109+x=180
Isolate the x, so subtract 109 from 180
x=71°

11/66= 6
4/x= 6
4•6= 24

hope this is clear :))
B is the irrational. C & D are rational as they can be written in a ratio, aka a simple fraction. A is rational as it simplifies to +/-2, a whole number.
