Consider the line in the coordinate plane that passes through the point (-5, 2) and the origin. Find the slope of a line perpend
icular to the line described.
A) -2/5
B) -5/2
C) 1/2
D) 5/2
1 answer:
Answer:
D) 5/2
Step-by-step explanation:
When the line goes through the origin, its slope is the ratio of y to x coordinates of points on that line. Thus the given line has slope ...
given slope = 2/-5 = -2/5
The perpendicular line will have a slope that is the opposite of the reciprocal of this value:
perpendicular slope = -1/(-2/5) = 5/2

Answer:
x = 5
Step-by-step explanation:
=(-5-√-75)/2=(-5-5i√ 3 )/2= -2.5000-4.3301i
x =(-5+√-75)/2=(-5+5i√ 3 )/2= -2.5000+4.3301i
x = 5

Answer:
113
Step-by-step explanation:
we need to know how much Lou has first !
so we have to do 682 / 6 which = 113
then 113 / 4 = 28.2
28.2 is how much Lou has
so we will go back and multiply the 4
28.2 x 4 =113
