Answer:
Lines a) and c) are perpendicular to each other.
Step-by-step explanation:
I'd suggest you draw a coordinate plane: just draw the x- and y-axes. Notice how these axes are PERPENDICULAR to one another.
Now note that the line y = 5 is parallel to the x-axis and x = 2 is parallel to the y-axis. That's all that's necessary for us to claim that x = 2 and y = 5 are perpendicular to each other.
y = (1/8)x and y = 8x - 5 are neither parallel to each other or perpendicular. If their slopes were negative reciprocals, e. g., 8 and -1/8, then the lines would be perpendicular (not true here).
One has only one owner and the other have several.
Answer:
880
Step-by-step explanation:
the train travels=220km in 4 hours
therefore, multiply 220 and 4
=220 x 4 = 880
so, the train travels 880 km in 9 hours
HAVE A GREAT DAY!
(5, 12) e (-10, -3)
x.......y...1
5.....12..1
-10..-3..1
12x -10y -15 + 120 -5y + 3x = 0
12x + 3x - 10y - 5y - 15 + 120 = 0
15x - 15y + 105 = 0 :(5)
3x - 5y + 21 = 0
m = -a/b
m = -3/-5
m(5) = 3/5
y-yo = m(x-xo)
y-14 = 3/5*(x-7)
y-14 = 3x/5 - 7/5
3x/5 - y + 14 - 7/5 = 0
3x/5 - 5y/5 + 70/5 - 7/5 = 0
3x - 5y + 70 - 7 =0
3x - 5y + 63 = 0
m(s) = -3/-5 = 3/5
m(r) = m(s) --> são paralelas
