Answer:
2/3
Step-by-step explanation:
To get the slope, you do (y2-y1)/(x2-x1).
You can also remember it as rise/run, as it is the change in y/change in x.
You can make either coordinate 1 or 2, just keep it consistent with the rest of the problem.
For this, I chose (-5, -7) to be 2, and (4, -1) to be 1.
Following the formula for slope, (y2-y1)/(x2-x1), you put the values in: (-7-{-1})/(-5-4).
-7 minus -1 is -6 and -5 minus 4 is -9.
Thus you get -6/-9. Don’t forget to simplify! A negaive divided by a negative is positive, and both 6 and 9 can be divided by 3. 3 goes into 6 TWO times and into 9 THREE times.
So, you get a positive fraction, 2/3.
Hope this helped.
25 cubic inches because 3 cones can fit into 1 cylinder exactly. So, divide 75 by 3 and you ed up with 25 cubic inches.
Answer: the speed of the submarine is 5miles per hour
Step-by-step explanation:
The submarine left Hawaii two hours before the aircraft carrier.
Let x = the speed of the submarine
The aircraft carrier traveled at 25 mph for nine hours.
After this time the vessels were 280 miles apart. This means that when they became 280 miles apart, the aircraft carrier has travelled for 9 hours. If the submarine was ahead of the aircraft carrier with 2 hours, that means that the submarine travelled 9 + 2 = 11 hours
Distance travelled = speed × time
Distance travelled by submarine will be 11 × x = 11x miles per hour
Distance travelled by aircraft carrier will be 25 × 9 = 225 miles per hour
If they are 280 miles apart, this would be their total distance. Therefore,
225 + 11x = 280
11x = 280 - 225 = 55
x = 55/11 = 5miles per hour
I think it means to write that in slope intercept form. there for, it’ll be y=8x+23. hope this helps
