Answer:

$\large\boxed{\large\boxed{slope=-2/5}}$

Explanation:

The problem is: <em>given the points (19,−2) and (−11,10) find the slope of the line that joins them.</em>

The <em>slope </em>of a line is the change in the y-coordinate over the change of the x-coordinate:

slope = rise / run = Δy / Δx

Thus:

$slope=[10-(-2)]/[-11-19]\\\\slope=12/(-30)\\\\slope=-12/30$

Simplify, dividing both numerator and denominator by 6:

$slope=-2/5\leftarrow answer$

Factor the expression.

g100num [7]

Answer:

(x + 1) (3 x^2 + 1)

Step-by-step explanation:

Factor the following:

3 x^3 + 3 x^2 + x + 1

Factor terms by grouping. 3 x^3 + 3 x^2 + x + 1 = (3 x^3 + 3 x^2) + (x + 1) = 3 x^2 (x + 1) + (x + 1):

3 x^2 (x + 1) + (x + 1)

Factor x + 1 from 3 x^2 (x + 1) + (x + 1):

Answer: (x + 1) (3 x^2 + 1)

What is the measure of angle A?

I am Lyosha [343]

First you have to find the angle B (check attachment)

$B = 180^{\circ} - 137^{\circ} = 43^{\circ}\\$

Then you can find the last angle inside the triangle, which I'll call C

$C = 180^{\circ} - 102^{\circ} - 43^{\circ} = 35^{\circ}$

Now you can find angle A

$A = 180^{\circ} - C = 180^{\circ} - 35^{\circ} = 145^{\circ}$
