-55 is an i
nteger.
It is not a whole number because it is negative.
It is not a natural number because it is not a whole number.
It is not irrational because it can be written as a fraction
.
Answer:
Step-by-step explanation:
Slope of a line passing through two points 
and 
is given by the formula,
Slope = 
Slope of the line PQ passing through the two points P(-8, 2) and Q(4, 2) will be,
Slope '
' = 
= 0
Therefore, slope of the line PQ parallel to the x-axis = 0
Slope of the line MN passing through the points M(8, 6) and N(8, -8) is,
Slope '
' = 
= ∞
Therefore, slope of the line MN parallel to y-axis is undefined.
Since, angle between the x-axis and y-axis is 90°,angle at the intersection point between the lines parallel to x and y axis will be 90°.
These lines are perpendicular to each other.
Make them both improper fractions.
77/10 - 19/5
Give them common denominators (multiply the second fraction by 2)
77/10 - 38/10
Subtract
39/10 = 3 9/10
Divide the speed value by 1.609,
1kilometer per hr=0.621mph
80kph=49.7097Mph
