AB and BC form a right angle at their point of intersection, B.
const2013 [10]

Answer:

The y-intercept of AB is <u>(4/3)</u> and the equation of BC is y = <u>(-1/6)</u> x + <u>(4/3)</u>

If the y-coordinate of point C is 13, its x-coordinate is <u>4</u>.

=====================================

Step-by-step explanation:

AB and BC form a right angle at their point of intersection, B.

So, AB ⊥ BC

A = (14 , -1) , B = (2,1)

<u>Part A: Find the y-intercept of AB.</u>

The general equation of the line y = mx + c

Where: m is the slope and c is constant represents y-intercept.

m = (y₂ - y₁)/(x₂ - x₁)

m = \frac{1 - (-1)}{2-14} = \frac{2}{-12} = - \frac{1}{6}

y = (-1/6) x + c

Substitute with the point (2,1) to find c

1 = (-1/6) * 2 + c

c = 1 + 2 *(1/6) = 4/3

y = (-1/6) x + 4/3

So,  <u>the y-intercept of AB is 4/3</u>

=======================================

<u>Part B: Find the equation of BC.</u>

BC ⊥ AB at point B

if m is the slope of AB, the slope of BC = (-1/m)

m = (-1/6)

So, the slope of BC =  (-1/m) = 6

The equation of the line BC ⇒ y = 6x + c

Substitute with the point (2,1) to find c

1 = 6 * 2 + c

c = 1 - 12 = -11

y = 6x - 11

=========================================

<u>Part C: Find x-coordinate of C if y-coordinate of point C is 13.</u>

The equation of the BC is y = 6x - 11

Substitute with the y-coordinate of point C = 13

13 = 6x - 11

6x = 13 + 11 = 24

x = 24/6 = 4

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

All triangles equal up to 180⁰. With that in mind, let's solve

Step-by-step explanation:

<em>x</em> + 124⁰ + 33⁰ = 180⁰

    \_______/

<em>x</em>    +   157⁰      = 180⁰

      -   157⁰         -157⁰

    _______   ______

<em>x</em>                      =   23⁰

<em>x</em> = 23⁰

The bolded part is your answer. I hope this helps!

Dafna1 [17]

Answer:

s+6+s+6+s+s+2s=102, s=18

Step-by-step explanation:

The perimeter is the sum of the side lengths, so

the equation is s+6+s+6+s+s+2s=102.

5s+12=102 \\ \\ 5s=90 \\ \\ s=18

Thepotemich [5.8K]

Answer:

g = -3

Step-by-step explanation:

-7g + 5 = 2 – g – 7g

Combine like terms

-7g + 5 = 2 -8g

5 = 2 + -g

3 = -g

-3 = g
