Answer:

8x - 8z.

Step-by-step explanation:

Let's first rearrange 6x-3y-z+2x+3y-7z where all the x's are together, all y's together, and all z's are together:

6x +2x + 3y - 3y - z - 7z.

First we combine like terms.

6x + 2x ⇒ 8x

3y - 3y ⇒ 0

z - 7z ⇒ -8z.

Since the y's result in 0, we do not include them.

Therefore, our answer is 8x - 8z.

What is the reference angle of -139 degrees

katrin [286]

41º

1) Since we want to find the reference angle for a -139º angle, we need to resort to the following formula

$Reference\:Angle\:\:Quadrant\:III=180^{\circ}-139^{\circ}=41^{\circ}$

2) Note that a -139 angle is in quadrant III, since negative angles are clockwise oriented

3) Thus the Reference Angle is 41º

Find the point slope equation for the line that passes through the points (7,-21) (-4,23)

zheka24 [161]

$\bf (\stackrel{x_1}{7}~,~\stackrel{y_1}{-21})\qquad (\stackrel{x_2}{-4}~,~\stackrel{y_2}{23}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{23-(-21)}{-4-7}\implies \cfrac{23+21}{-11}\\\\\\ \cfrac{44}{-11}\implies -4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-21)=-4(x-7)\implies y+21=-4(x-7)$
