X = 1 , y = - 2
Hope this helped
If the slopes of the 2 lines are equal then they are parallel.
If m1m2 = -1 (where m1 and m2 are the slopes of the 2 lines) then they are perpendicular.
If the 2 slopes do not match either the first or second conditions then they are neither parallel or perpendicular.
Answer:
6.4 seconds
Step-by-step explanation:
Using the second equation of motion.
d= 200m/s.
a= 9.8ms^-1 . Acceleration due to gravity.
t= time.
substituting,
t=
t= 6.4 seconds
Answer:
32
Step-by-step explanation:
Substitute 4 for x, -3 for y and -5 for z.
Then the original expression becomes:
-4(-3 - 5), or -4(-8) = 32
