Determine an equation for the right bisector of the line segment with endpoints J(-5,3) and K(3,-2)

Mathematics

Norma-Jean [14]3 years ago

Answer:

y=1.6x+2.1

Step-by-step explanation:

we know that

The right bisector of the line segment JK is a perpendicular line to the segment JK that pass through the midpoint of segment JK

step 1

Find the midpoint JK

The formula to calculate the midpoint between two points is equal to

M(\frac{x1+x2}{2},\frac{y1+y2}{2})

we have

J(-5,3),K(3,-2)

substitute the values

M(\frac{-5+3}{2},\frac{3-2}{2})

M(\frac{-2}{2},\frac{1}{2})

M(-1,\frac{1}{2})

step 2

Find the slope JK

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

J(-5,3),K(3,-2)

substitute

m=\frac{-2-3}{3+5}

m=\frac{-5}{8}

m=-\frac{5}{8}

step 3

Find the slope of the line perpendicular to the segment JK

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

m_1*m_2=-1

we have

m_1=-\frac{5}{8}  ----> slope of segment JK

Find m_2

substitute

(-\frac{5}{8})*m_2=-1

m_2=\frac{8}{5}

step 4

Find the equation for the right bisector of the line segment JK

The equation in point slope form is equal to

y-y1=m(x-x1)

we have

m=\frac{8}{5}

point\ M(-1,\frac{1}{2})

substitute

y-\frac{1}{2}=\frac{8}{5}(x+1)

Convert to slope intercept form

isolate the variable y

y-\frac{1}{2}=\frac{8}{5}x+\frac{8}{5}

y=\frac{8}{5}x+\frac{8}{5}+\frac{1}{2}

y=\frac{8}{5}x+\frac{21}{10}

y=1.6x+2.1

Mr Abraham is able to divide the learners in his mathematics class into equal groups of 2, 5 or 6 without leaving any learners o
IRISSAK [1]

Answer:

30

Step-by-step explanation:

Find the lowest number divisible by both 6, 5, and 2.

To start, let's list off the numbers divisible by six, and see if we can check any of them off for 5. Since both 2 and 6 are even numbers, we know that if a number is divisible by 6, it's divisible by 2.

6 12 18 24 30 36 42 48 54 60

All of these numbers are divisible by two. Let's find the lowest one that is divisible by 5. We know this by either the umber ending in 5 or 0.

30 is the lowest number that is divisible by 2, 5, or 6.

The Farrells save $150 each month for their next summer vacation.Write an equation that they can use to find ,s, their savings a
Andrei [34K]

Answer:

<u>s=150m</u>

Step-by-step explanation:

Using slope intercept form, you can come p with the equation, <u>s=150m</u> where 150 is the savings per month and you were not given a starting point which would be y.

y=mx+b

<u>s=150m</u>

What is the answer 4+3x = -2y
lilavasa [31]
First add 2y to both sides
so 4 + 3x + 2y = 0
then subtract 4 from both sides
so 3x + 2y = -4
that is standard form
now subtract 3x from both sides
2y = 3x - 4
now divide by 2 on both sides
y = 1.5x - 2
This is solved for y and is slope intercept form
starting from original subtract 4 from both sides
so 3x = -2x -4
now divide by 3 on both sides
so x = -2/3x -4/3
this is solved for x
hope any of that is what you needed.
