What is Distance?
Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.
We are given:
The rate at which two objects drift apart in 1 year = 25 km
To calculate the distance between the two objects in 10 years, we apply unitary method:
The distance, the two objects has drifted apart in 1 year is 25 km
So, the distance, the two objects has been drifted apart in 10 years, will be = 
Therefore, the distance between the two objects in 10 years will be 250 kilometers.

Answer:
D
-5x + y = 7
x+3y = 5
Step-by-step explanation:
when you graph the equations, they are parallel. as you know, solutions are the point where the lines meet. if they are parallel, it's not possible for the lines to intersect.
The first given equation is:
x - 7y = -20
We can rewrite this equation as follows:
x = 7y - 20 ...........> equation I
The second given equation is:
-3x + 9y = 36 ..........> equation II
Substitute with equation I in equation II to get the value of the y as follows:
-3x + 9y = 36
-3(7y-20) + 9y = 36
-21y + 60 + 9y = 36
-12y = 36-60 = -24
y = (-24) / (-12) = 2
Now use the value of the y and substitute in equation I to get the value of the x as follows:
x = 7y - 20
x = 7(2) - 20 = 14 - 20 = -6
Based on the above calculations:
x = -6
y = 2
Answer:
4.5 miles
Step-by-step explanation:
On the graph,
- Elm station is located at (-3,-6)
- Oak station is located at (-1,-2)
We use the distance formula to find the distance between Elm and Oak.
Answer: C:10
Step-by-step explanation:
Equation of a line passes through (a,b) and (c,d) :
Equation of line passes through A(-2,8) and B(4,14) will be :
For y-intercept , put x= 0 , we get y= 10
So, the y-intercept = 10
Thus , correct option = C:10
