Answer:
1462.5
Step-by-step explanation
225 mph means of course 225 miles per hour
225 x 6 is 1350 and then you have to do 225/2 which is 112.5 to find what half of 225 is then you add 1350+112.5 to get 1462.5
Answer:
False.
Step-by-step explanation:
If they have the same slope and same intercept they will have the same line. So they will have infinite solutions.
Answer:
No this is not the same as cos(2Ф)
Step-by-step explanation:
First I changed the 
Ф into 1-
Ф
I then foiled the (1-2Ф)(1-Ф) and that resulted in 1-Ф-2Ф+2
Ф
From there, I then cancelled the two 2Ф and combined like terms and was left with 1-3Ф
Now 1-3Ф ≠ cos(2Ф)
5m + 4m = 72
Combine like terms.
9m = 72
Divide both sides by 9.
m = 8
