Answer:
The coordinates of C is (-8,1)
Step-by-step explanation:
Looking at the attached image, you'd see that, AB is 1 and BC is 1, that's because we are told that ratio of AB to AC is 1:2 meaning, AC is 2 and AB is 1. Therefore for that ratio to be satisfied BC has to be 1 so that AC would be 2.
Now let's assume the coordinates of C is
.
To get it's coordinates, we use the section formula:

Where (m,n) is the (AB, BC)
Therefore we have

This gives:

and 
From there x = -8 and y = 1
Therefore the coordinates of C is (-8, 1).
Answer:
y = c/b - (A x)/b
Step-by-step explanation:
Solve for y:
A x + b y = c
Hint: | Isolate terms with y to the left hand side.
Subtract A x from both sides:
b y = c - A x
Hint: | Solve for y.
Divide both sides by b:
Answer: y = c/b - (A x)/b
Answer:
207,50
Step-by-step explanation:
1% = 2,5
2,5x25 = 62,5 250 - 62,5 = 187,5
2,5x8 = 20
187,5+20= 207,50
