Answer:
B
Step-by-step explanation:
recall that any radical expression has real solutions only if A is not negative. (otherwise you will have imaginary solutions)
hence in this case we have
,
for real solutions, 8x must be ≥ 0,
since 8 is a positive number, x must be ≥ 0 (answer)
For this case we have the following conversions:
We must apply the conversions to move from kilometers to feet.
We have then:
Rounding off we have:
10501 feet
Answer:
there are 10501 feet in 3.2 km

For the graph of y = -8 the line is horizontal, which means the slope = 0. A parallel line has the same slope so one equation could be y = 2. A perpendicular line has an opposite slope so since our slope = 0 the opposite of that slope is 
which a line that is perpendicular to y = -8 could be x = -3. Also notice that these two lines form a 90 degree angle.
