A perpendicular bisector, CD is drawn through point C on AB.

STALIN [3.7K]

<u>Answer</u>

B(18/5,0)

<u>Explanation</u>

First we find the coordinates of C;

C (x, y) = [(-3+7)/2, (2+6)/2]

= (2, 4)

Find the equation of CD.

slope = (6-2)/(7--3)

= 4/10 = 2/5

slope of CD = -5/2

-5/2 = (y - 4)/(x - 2)

-5/2(x - 2) = y - 4

(-5/2) x + 5 = y - 4

y = (-5/2)x + 9

For the x-intercept y = 0

∴ y = (-5/2)x + 9

0 = (-5/2)x + 9

5/2 x = 9

x = 2/5 × 9

= 18/5

x-intercept = (18/5, 0)

iragen [17]

Answer:

$m=50$

General Formulas and Concepts:

<u>Pre-Alg</u>

Order of Operations: BPEMDAS

<u>Algebra I</u>

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

Step-by-step explanation:

<u>Step 1: Define</u>

Point (40, 3000)

Point (60, 4000)

<u>Step 2: Find slope </u><em><u>m</u></em>

Substitute: $m=\frac{4000-3000}{60-40}$
Subtract: $m=\frac{1000}{20}$
Divide: $m=50$
