If angle ec is a bisector then angles Bec and ced are the same making them both 4x+1. we know a line segment equals 180°. so if we take the 11x-12 and add it to 2(4x+1) we end up with 19x-10=180. you add 10 to both sides and get 19x=190 then you divide by both sides. you'll end up with x=10. you plug In the 10 with aeb and aec and add them together to get 139°. if you're looking for the equation, it's 15x-11.

3x - 2(2x - 5) = 2(x + 3) - 8

nataly862011 [7]

Answer:

x = 4

Step-by-step explanation:

Hello!

We can solve for x by expanding the parentheses and isolating x.

<h3>Solve for x</h3>

3x - 2(2x - 5) = 2(x + 3)-8
3x - 4x + 10 = 2x + 6 - 8
-x + 10 = 2x - 2
10 = 3x - 2
12 = 3x
x = 4

The value of x is 4.

What is the x-intercept of the graph?

Umnica [9.8K]

Answer: (6,0)

Step-by-step explanation: To find the x-intercept, we plug a 0 in for y.

So we have 2x - 3(0) = 12.

Simplifying from here, we have 2x = 12.

Now divide both sides by 2 and we get <em>x = 6</em>.

So our x-intercept is 6.

This means that our line crosses the x-axis 6

units to the right of the origin or at the point (6,0).

What is the distance between points A and B shown in the graph below

Bas_tet [7]

Answer:

$D = 7\sqrt 2$

Step-by-step explanation:

Given

$A = (-3,-4)$

$B = (4,3)$

Required

The distance between them

This is calculated as:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

So, we have:

$D = \sqrt{(3-(-4))^2+(4-(-3))^2}$

$D = \sqrt{7^2+7^2}$

$D = \sqrt{2(7^2)}$

$D = 7\sqrt 2$
