Answer:
1.4 hrs
Step-by-step explanation:
Given ;
The distance to be covered by the motorcycles is 196 miles
1st motorcycle speed= 65 m/h
2nd motorcycle speed= 75 m/h
Find relative speed of the motorcycles= 65+75=140m/h
Time of meeting= Distance to be covered/relative speed
Time of meeting=196/140=1.4 hrs
i think the answer is 6, sorry if im wrong ;-;
Answer:
.
Step-by-step explanation:
A line that goes through
and
where
would have a slope of
.
The slope of the line that goes through
and
would thus be:
.
Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is
.
Thus, if
and
denote the slope of the first and second lines in this question,
since the two lines are perpendicular to one another. Since
, the slope of the first line would be:
.
Given that the first line goes through the point
, the point-slope equation of that line would be:
.
.
Substitute in
to find the
-coordinate of the point in question:
.
open circle means less than or greater than (NO EQUALS)
line to the left means less than
x< 2
Choice A
closed circle means less than or equal to or greater than or equal to
line to the left means less than
x<=-4.25
Choice B
