first off, let's solve the "given" line for "y", that way we can put it in slope-intercept form to see what its slope might be.
well, a parallel line to that one, will have the same exact slope, so then, we're really looking for the equation of a line whose slope is -5 and runs through (0 , 12)
You run in a race at a rate of 4 miles per hour for 60 minutes and your friend runs in the race at a rate of 3.5 miles per hour for 60 minutes.
Your friend starts running 10 minutes before you, and you run for a half hour
Friend: 40/60 × 3.5 = 2 1/3 miles
You: 30/60 × 4 = 2 miles
You won't catch up in a half hour
4 mph: = 4×5280
_______ =352 ft/min; y = 352x
60
3.5 mph: = 3.5×5280
________ = 308 ft/min; y = 308(x+10)
60
( ____ this is a fraction bar. lol)
You take about 70 min for you to catch your friend
Answer:
5/2
Step-by-step explanation:
The slope of a line passing through two points is the ratio between the difference of the y coordinates and the difference of the x coordinates. In formulas, you have
If you plug your values, you have
which is undefined.
In fact, since the two points share the same x coordinate, the segment AB is vertical, and the slope is not defined for vertical lines.
Answer: $108
Step-by-step explanation:
3% = 0.03
1800 x 0.03 x 2 = 108
