Answer: The mid-point of AC easy to calculate.
It is at ((5+3)/2,(5−1)/2)=(4,2) .
What you really asked was the coordinates of the point 3/4 of the way from A to C, and the calculation is very similar. I think of it as giving a “weighting” to the nearest point. So in this case we give a weighting of 3 to point C and 1 to point A.
Then =((5+3∗3)/4,(5−1∗3)/4)
So =(3½,½) .
CHECK:
Distance
2=(5−3½)2+(5−½)2
=(3/2)2+(9/2)2=9/4+81/4
=90/4
So the distance =310‾‾‾√/2
And the distance
2=(3½−3)2+(½+1)2
=1/4+9/4=10/4
And so the distance BC is 10‾‾‾√/2 which is indeed one third of the distance AB.

The slope is 3x+2 for green line
the slope is 3x-4 for blue line
so basically you he answer is 3x because they have the same slope
Answer:
[0, infinity)
Step-by-step explanation:
The square root is a function that is not defined for negative values, since they belong to another space, the complex space.
Having that in mind that means
x>=0
That's it
Answer:
7(x+11)=9x-18
7x + 77 = 9x - 18
7x - 7x + 77 = 9x - 7x - 18
77 = 2x - 18
18 + 77 = 2x - 18 + 18
95 = 2x
95/2 = 2x/2
x = 47.5
Step-by-step explanation:
1. distribute the bracket
2. subtract 7 from both sides
3. add 18 to both sides
4. divide both sides by 2
