Answer:
y = 1/3 x.
Step-by-step explanation:
The slope of the given line is
(4 - (-2) / 2 - 4)
= -3.
So the slope of the line perpendicular to it = -1 / (-3) = 1/3.
This line also passes through the point (3, 1) so its equation is ( by the point-slope form):
y - 1 = 1/3(x - 3)
y - 1 = 1/3x - 1
y = 1/3 x (answer).

Step-by-step explanation:
r = 7x + 7y
8 = 7x + 7 ×2
8 = 7x + 14
7x = 14 - 8
7x = 6
X = 6 / 7
Why not actually graph |x|=1? You will find that x = 1 and x = -1 are solutions.
Thus, "closed circles on -1 and 1 with no line" is correct.
Answer:
greatest - romania; least - us; proof below
Step-by-step explanation:
to answer this question we must first find all the population densities by dividing the population by the area
for the us
272648000/9364520 = 29.115
for romania
22609000/237391 = 95.2394994
for ghana
18339000/237533 = 77.2061145
this means that the us has the lowest population density
this also means that romania has the highest population density
