Answer:
(-1,9)
(0,3)
(1,-3)
(5,-27)
Step-by-step explanation:
Plug x values into the equation.
It is a 50 percent chance. This is because there is only two possibilities that can occur. It does not matter how many times the coin has been flipped.
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:
15 and 5 hours.
Step-by-step explanation:
Call x the time taken by the first chap, and y the second.
Let's divide by 5 and play with the LHS of the first equation a bit:
we know how much x+y is ( first equation!) let's solve.
At this point it's easy to check that
