When reflected across the y axis, the x coordinate becomes the opposite but the y coordinate stays the same, so N is (2, -5)
when reflected across the x axis, the y coordinate becomes the opposite but the x coordinate stays the same, so R is (2, 5)
Answer:
v = -5, t = -13. , d = -12
Step-by-step explanation:
29) 3v - 9v = 30
Simplifying gives us -6v = 30. Then dividing both sides by -6 reaches our answer of v = -5.
30)12t - 8t = -52
Simplifying gives us 4t = -52. We can divide both sides by 4 to reach a conclusion that t = -13.
31) -8d - 5d + 7d = 72
Simplifying gives us -6d = 72. We can then divide both sides by -6. In doing so, we can achieve our answer that d = -12.
The greatest common factor (GCF) of 48 and 78 is: 6
Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Factors of 78: 1, 2, 3, 6, 13, 26, 39
The common factors between the two numbers are 1, 2, 3, and 6, but considering 6 is the highest number out of them, it is the greatest common factor.
Answer:
It’s 60miles
Step-by-step explanation:
We assume the trip is "d" miles and that the "extra hour" refers to the additional time that a current of 2 mph would add. That is, we assume the reference time is for a current of 0 mph.
The time with no current is ...
time1 = distance/speed
time1 = d/12 . . . . hours
With a current of 2 mph in the opposite direction, the time is ...
time2 = d/(12 -2) = d/10
The second time is 1 hour longer than the first, so we have ...
time2 = 1 + time1
d/10 = 1 + d/12
6d = 60 + 5d . . . . multiply by 60
d = 60 . . . . . . . . . subtract 5d
The one-way distance is 60 miles.
