Answer:
Q (2.5, -4)
Step-by-step explanation:
Let A (1, -5), C = (10, 1), find Q (x, y), so that AQ:QC = 1:5
AQ = (x - 1, y + 5)
QC = (10 - x, 1 - y)
AQ:QC = 1:5
so 5*AQ = QC
5(x - 1) = (10 - x)
5(y + 5) = 1 - y
Solve them:
5x - 5 = 10 - x
6x = 15
x = 15/6 = 2.5
5y + 25 = 1 - y
6y = -24
y = -24/6 = -4
Then answer is Q (2.5, -4)
Answer:
(3-4)+2*6=11
Step-by-step explanation:
3-4=-1,
2*6=12
-1+12=11
Answer:
In order for this to be true, subtract 2.5 - 10 = 7.5. Then a,+b =c
Step-by-step explanation:
10.00
- 2.50

7.50
First we put the numbers in order....very important
67,76,76,(82),84,87,93
the median is the middle number....so it is 82
