MArishka [77]

Answer:

x = 80°
y = 130°

Step-by-step explanation:

The interior is a parallelogram when adjacent angles are supplementary. This requires ...

(x -30)° + (x +50)° = 180°

2x + 20 = 180 . . . . . . . . . . . collect terms, divide by °

2x = 160 . . . . . . . . . . . . . . . subtract 20

x = 80 . . . . . . . . . . . . . . . . . divide by 2

Then the angle x+50 is ...

(x +50)° = (80 +50)° = 130°

This is also the measure of the angle marked y.

For the lines to be parallel, x = 80, y = 130°.

What is the equation of this line in standard form? 8x−7y=−25 8x−9y=23 8x−9y=−23 9x−8y=23 Number graph ranging from negative fiv

Gnoma [55]

Answer:

The equation of line is:

$8x-9y=-23$

Step-by-step explanation:

We are given that a graph is a that passes through two points:

$(-4,-1)$ and $(\dfrac{1}{2},3)$

We know that the equation of line passing through two points:

$(a,b)$ and $(c,d)$ is given by:

$y-b=\dfrac{d-b}{b-a}\times (x-a)$

Here we have:

$(a,b)=(-4,-1)$ and $(c,d)=(\dfrac{1}{2},3)$

Hence, the equation of line is:

$y-(-1)=\dfrac{3-(-1)}{\dfrac{1}{2}-(-4)}\times (x-(-4))\\\\y+1=\dfrac{3+1}{\dfrac{1}{2}+4}\times (x+4)\\\\y+1=\dfrac{4}{\dfrac{9}{2}}\times (x+4)\\\\y+1=\dfrac{4\times 2}{9}\times (x+4)\\\\y+1=\dfrac{8}{9}\times (x+4)\\\\9\times (y+1)=8\times (x+4)\\\\9y+9=8x+8\times 4\\\\9y+9=8x+32\\\\8x-9y=9-32\\\\8x-9y=-23$
