Answer:
22 miles in 11 hours!
Step-by-step explanation:
We already know a ghost crab can travel 12 miles in 6 hours.
Now, we just need to find the how many miles per hour the crab walks.
We simply divide 12 miles by 6 hours which gives us 2 miles in 1 hour.
That means, we multiply 11 by 2 which gives us 22 miles!
The ghost crab can travel 22 miles in 11 hours. When you find the rate of change by dividing 12 by 6, it gives you 2 m/h. That enables you to find the amount of miles by multiplying 11 hours by two which gives you 22!
Answer:
Step-by-step explanation:
The have the same slope, -1, but different y-intercepts. The lines are parallel.
Answer: (2;-9).
Step-by-step explanation:
Answer:y = - 5x - 7
Step-by-step explanation:The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
here m = - 5 and b = - 7, hence
y = - 5x - 7 ← equation of line
Cot^2x - cot^2x cos^2x
= cot^2x - {(cot^2x)(cos^2x)}
= cot^2x { 1 - cos^2x }
= cot^2x { sin^2x }
= (cos^2x/sin^2x) { sin^2x }
= cos^2x
