Answer:

<h2>The slope of AB = 2</h2>

Step-by-step explanation:

We have a circle described on the triangle. If one side of the triangle is the diameter of the circle, then the triangle is the right triangle.

Therefore m∠B = 90°.

AB is perpendicular to BC.

Let

k: y = m₁x + b₁ and l: y = m₂x + b₂

l ⊥ k ⇔ m₁m₂ = -1 ⇒ m₂ = - 1/m₁

We have the slope of BC m₁ = - 1/2.

Therefore the slope of AB m₂ = - 1/(- 1/2) = 2

|-4+5x|=16<br> Help I'm confused.

Anna11 [10]

Answer:

x=4

Step-by-step explanation:

|-4 + 5x|=16

First, combine like terms and use the properties of equality to get all variables on one side of the equation and the numbers on the other.

|5x - 4| = 16

Apply absolute value

5x - 4 = 16

5x - 4 = -16

Add 4 to both sides

5x = 20

5x = -12

Divide both sides by 5

x = 4

hope this helps :)

If l||m, find the value of x.

Vinil7 [7]

l || m
When two parallel lines are intersect by a transversal, then the corresponding angles are equal.
$11x - 47 = 6x - 2 \\ = > 11x - 6x = - 2 + 47 \\ = > 5x = 45 \\ = > x = 9$

Pleaseeeee helpppppppppp

statuscvo [17]

Answer:

1) 15ft

2) 21m

Step-by-step explanation:

1) 10ft/4ft = x/6ft

multiply both sides by 6

$\frac{10}{4} \times 6 = \frac{x}{6} \times 6$

60/4 = x

x= 15ft

2) 28m/x = 12m/9m

multiply both sides by 1/28

$\frac{28}{x} \times \frac{1}{28} = \frac{12}{9} \times \frac{1}{28}$

1/x = 12/252

1/x = 1/21

by equivalence, x= 21m
