Answer:

D: (2x + 20°) + x° = 180°

Step-by-step explanation:

Supplementary angles add up to 180°, so that rules out A and C as possible answers.

Answer B has only one angle, so that is out too.

2x + 20° represents one angle, and x represents the other angle

Answer:

2 and - $\frac{1}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3y = 6x + 9 ( divide all terms by 3 )

y = 2x + 3 ← in slope- intercept form

with slope m = 2

(i)

Parallel lines have equal slopes, thus

the slope of line t is 2

(ii)

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{2}$ , thus

the slope of line r is - $\frac{1}{2}$

Calculate the average rate of change for the given graph from x = –2 to x = 0 and select the correct answer below.

Gwar [14]

$\frac{6-0}{0+2} = \frac{6}{2} =$

wel

X = 78 degrees

Explanation:
Using the alternate exterior angle of 33 degrees, the angle to the left of x would also be 33 degrees
Using this we add up 69 and 33 = 102
Then we would do 180-102 since a straight line has a total of 180 degrees
The answer would be 78 degrees
