Answer:
x = 5 x = 1
Step-by-step explanation:
−3|x − 3| = −6
Divide each side by -3
−3/-3|x − 3| = −6/-3
|x − 3| = 2
An absolute value is equal to a positive and negative solution
x-3 =2 and x-3 = -2
Add 3 to each side
x-3+3 = 2+3 x-3+3 = -2+3
x = 5 x = 1
Umm I think it is 1+1 equals 2
Answer:
(1-cos^2 x)(1+tan^2 x)=tan^2 x is an identity

Answer:
∆v = 32 km/h
the difference, in km/h, between the average speed of their trains is 32 km/h.
Step-by-step explanation:
For Ash's Train;
Distance travelled d1 = 80km
Time taken t1 = 50 minutes = 5/6 hour
Average speed = distance travelled/time taken
v1 = d1/t1
Substituting the values;
v1 = 80/(5/6)
v1 = 96km/h
For Misty's train;
Total distance travelled d2 = 160 km
Time taken t2 = 15:05 - 12:35 = 2 hours 30 minutes
t2 = 2.5 hours
v2 = d2/t2 = 160/2.5
v2 = 64 km/h
the difference, in km/h, between the average speed of their trains is;
∆v = v1 - v2 = 96km/h - 64 km/h = 32 km/h
∆v = 32 km/h
the difference, in km/h, between the average speed of their trains is 32 km/h.
