What is the equation of the perpendicular bisector of the segment joining points A(1, 1) and B(5, 7)?
Elden [556K]
Bisector must pass through the mid-point, so we have to find out that mid-point of the segment:

mid point = x₁+x₂ / 2 , y₁+y₂/2
= 1 + 5 / 2 , 1 + 7 / 2
= 6/2 , 8/2
= (3, 4)

Slope of given segment = m = y₂-y₁ / x₂- x₁
m = 7-1 / 5-1
m = 6/4
m = 3/2

Now, segment which is perpendicular, will have the opposite & reciprocal slope, So, it would be: -2/3

We know, y - y₁ = m(x - x₁)
y - 4 = -2/3(x - 3)
y - 4 = -2/3x + 2
y = -2/3x + 6

In short, Your Final Answer would be: y = -2/3x + 6

Hope this helps!

professor190 [17]

Answer:

Step-by-step explanation:

3x -8 = 2x + 5

x - 8 = 5

x = 13

3(13) - 8 + 2(13) + 5

39 - 8 + 26 + 5

31 + 31 = 62

There are 250 votes tallied in a school election with 3 candidate:A, Candidate B, and Candidate C. If 150 of the votes are for c
Tanya [424]

The answer is 75 and here's why.

Let's figure out the amount of remaining votes to prove this.

250 total votes   -    150 votes for candidate a = 100 votes.

                minus ↑ sign

Candidate B received 25% of the votes, so let's find<u> 25% of 100</u>

<u>100 * 0.25 = 25 votes</u>

Candidate B only got 25 votes (that's kinda sad, poor guy)

<u>100 - 25 votes = the # of votes candidate C got </u>

Candidate C got 75 votes!
