Answer:
(#14 - supplementary) x = 10.5
(#15 - supplementary) x = 10

Explanation:
For these problems, we must know that a supplementary angle can be viewed as a sum of angles that add to 180 degrees. With this known, we can write our equations to find x.

(#14)
15x - 12 + 5x - 18 = 180
20x - 30 = 180
20x = 210
x = 10.5

(#15)
6x + 13 + 14x - 33 = 180
20x - 20 = 180
20x = 200
x = 10

Hope this helps.

Cheers.

How do you find the slope of a line?

VladimirAG [237]

Answer:

You use rise over run (rise/run) which is the x and y coordinates. You count how many to the going up or down then you count left to right. Hope this is useful of helpful! :)

6. Find the slope of AB, given A (3,-1) and B (-1/3, 2) *

Elena-2011 [213]

Answer: $-\frac{9}{10}$

Step-by-step explanation:

Just plug these points into the slope formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

A: (3,-1) = $(x_{1}, y_{1})$

B: (-1/3, 2) = $(x_{2}, y_{2})$

Now solve.

$\frac{2- (-1)}{-\frac{1}{3} - 3 }$

Simplify the numerator by changing the negative and minus to positive: $2 +1$

This simplifies now to 3.

The denominator needs to be simplified by finding a common denominator.

$-\frac{1}{3} -\frac{3}{1}$

The 3/1 needs to be multiplied by 3 on the top and bottom to get. $-\frac{1}{3} - \frac{9}{3}$

Now with a common denominator we can subtract: $-\frac{10}{3}$

Now we can put our simplified denominator and numerator back together.

$\frac{3}{-\frac{10}{3} }$

Now KCF, keep change flip.

$\frac{3}{1} *- \frac{3}{10}$

Now multiply across.

$-\frac{9}{10}$

This is the final answer as it cannot be simplified any further.
