What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?

frosja888 [35]

Complete Question:

The given line segment has a midpoint at (3, 1). On a coordinate plane, a line goes through (2, 4), (3, 1), and (4, -2).

What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?

Answer:

$y = \frac{1}{3}x$

Step-by-step explanation:

From the question, we understand that the line goes through $(2, 4), (3, 1), and\ (4, -2).$

First, we calculate the slope of the above points

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where

$(x_1,y_1) = (2,4)$

$(x_2,y_2) = (3,1)$

$m = \frac{1 - 4}{3 - 2}$

$m = \frac{-3}{1}$

$m = -3$

Also; from the question, we understand that the line segment is perpendicular to the above points.

This slope (m2) of the line segment is calculated as:

$m_2 = -\frac{1}{m}$

Substitute -3 for m

$m_2 = -\frac{1}{-3}$

$m_2 = \frac{1}{3}$

Lastly, we calculate the equation of the line using:

$y - y_1 = m_2(x - x_1)$

The line segment has a midpoint at (3, 1)

So:

$y - 1 = \frac{1}{3}(x - 3)$

Open bracket

$y - 1 = \frac{1}{3}x - 1$

Add 1 to both sides

$y - 1 +1= \frac{1}{3}x - 1+1$

$y = \frac{1}{3}x$

Hence, the equation of the line segment is: $y = \frac{1}{3}x$

Answer:

Confused as well

Step-by-step explanation:

If there are hypothetically 10 hours a day with 100 minutes an hour and 100 seconds per minute

at 6 pm there would be 18 hours gone in the day

18 normal hours are equal to 18*60*60 = 64800 seconds

(64800 seconds) / 10000 ( for hours)

6:48 would be the replacement time

but this answer is wrong bc it's not an option

b. Carlos monthly office supply budget is $250. He needs to buy ink cartridges which cost $40 a piece. He will need to save at l

Tju [1.3M]

ANSWER

Find out the what is the range of ink cartridges he can buy and still have enough money left over for the reams of paper.

To proof

let us assume that the number of the ink cartridges buy be x.

As given

Carlos monthly office supply budget is $250.

He needs to buy ink cartridges which cost $40 a piece.

He will need to save at least $50 of his budget for reams of paper.

than the inequality is written in the form

$250 - 40 x \leq 50 \\ 40x = 200 \\ x\leq \frac{200}{40}$

x ≤ 5

the range of the ink cartridges he can buy be 0 ≤ x ≤ 5 when he saves

at least $50 of his budget for reams of paper.

Hence proved

Which expression finds the length of side b of this right triangle?

tatyana61 [14]

Answer:

$b=\sqrt{c^{2} -a^{2} }$

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

$b^{2} =c^{2} -a^{2}$

$b=\sqrt{c^{2} -a^{2} }$
