Answer:

a. The x coordinates of the vertices are transformed as follows: (x, y) --> (−x, y)

b. The y coordinates of the vertices don't change.

c. The image is reflected across the y-axis.

Step-by-step explanation:

The rule to follow for reflecting a figure across the y-axis is to take the original coordinate (x, y) and change it to (−x, y)

Answer:

$x=\frac{-1}{6}$

Step-by-step explanation:

$9(x+1) -4x = 5-(x-3)$

$9(x+1) -4x = 5-(x-3) \\$

$9x+9\cdot1-4x=5-\left(x-3\right)$

$9x+9-4x=5-\left(x-3\right)$

$\left(9x-4x\right)+9=5-\left(x-3\right)$

$5x+9=5-\left(x-3\right)$

$5x+9=5-x+3$

$5x+9=-x+\left(5+3\right)$

$5x+9=-x+8$

$5x+9=-x+8$

$5x+9+x=-x+8+x$

$5x+x+9=-x+8+x$

$6x+9=-x+8+x$

$6x+9=-x+x+8$

$6x+9=8$

$6x+9=8$

$6x+9-9=8-9$

$6x=8-9$

$6x=-1$

$\frac{6x}{6}=\frac{-1}{6}$

$x=\frac{-1}{6}$

. What does the line y = 3x - 7 look like

Norma-Jean [14]

<span>y = 3x - 7

3 = slope
-7 = y intercept

This line would cross the y intercept at -7, and go up by 3 (slope). </span>

The sum of measures of alternate interior angles of two parallel lines is 210°. What are the measures of these angles?

torisob [31]

The answer is 105. Alternate interior angles of two parallel lines are congruent(meaning they are the same). 210/2=105, also the answer has to be below 180 degrees but more than 0.
