Answer:
Parallel
Step-by-step explanation:
in a Standard from equation, Ax+By=C
slope=-A/B
The slope of first line is -3/-1=3
The slope of second line is -6/-2=3
Same slopes but different C values mean they r parallel.
Let d represent the distance of the destination from the starting point.
After 45 min, Henry has already driven d-68 miles. After 71 min., he has already driven d-51.5 miles.
So we have 2 points on a straight line:
(45,d-68) and (71,d-51.5). Let's find the slope of the line thru these 2 points:
d-51.5 - (d-68) 16.5 miles
slope of line = m = ----------------------- = ------------------
71 - 45 26 min
Thus, the slope, m, is m = 0.635 miles/min
The distance to his destination would be d - (0.635 miles/min)(79 min), or
d - 50.135 miles. We don't know how far his destination is from his starting point, so represent that by "d."
After 45 minutes: Henry has d - 68 miles to go;
After 71 minutes, he has d - 51.5 miles to go; and
After 79 minutes, he has d - x miles to go. We need to find x.
Actually, much of this is unnecessary. Assuming that Henry's speed is 0.635 miles/ min, and knowing that there are 8 minutes between 71 and 79 minutes, we can figure that the distance traveled during those 8 minutes is
(0.635 miles/min)(8 min) = 5.08 miles. Subtracting thix from 51.5 miles, we conclude that after 79 minutes, Henry has (51.5-5.08), or 46.42, miles left before he reaches his destination.
35. is c : square root of 64 is 8 and the square root of 8 can be simplifed to 4 x 2, square root of 4 is 2
36 is d : Denominator of the fraction represents what it is being rooted by and the numerator is what the regular number is squared by.
Answer:
C. 5x + 11 = 36
Step-by-step explanation:
You can see in the diagram that there are 5 x variables and eleven which make up the total diagram that says 36 so it would have to be 5x+11 = 36
Answer:
Bess has been keeping track of the storm for 14 hours.
Step-by-step explanation:
The tropical storm has been moving at 15 miles per hour.
Bess recorded that the storm moved 135 miles yesterday and 75 miles today. Total distance covered by storm is
The relationship between distance speed and time is defined as
Therefore, Bess has been keeping track of the storm for 14 hours.
