Answer:

2x + 120 = 180 (being co interior angle)

or, 2x = 180 - 120

or, 2x = 60

or, x = 60/2

or, x = 30

therefore 2x = 2* x = 2* 30= 60

Two parallel lines are there
Sum of angles =180
Add them
(2X-20)+(3X+10)=180
5X-10=180
5X=180+10
5X=190
X=190/5
X=38

Plz help with slope question

nasty-shy [4]

Answer:

The equation in slope-intercept form:

$y = -3x - 4$

Step-by-step explanation:

Use the point-slope formula:

$y-y_{1} = m (x-x_{1})$

Use the given slope $-3$ and point $(0,-4)$ for the formula:

$y + 4= -3 (x-0)$

-Then, you solve the formula:

$y + 4 = -3 (x-0)$

$y+4 - 4 = -3 (x-0) -4$

$y = -3x - 4$

The equation, which is in slope-intercept form:

$y = -3x - 4$

marin [14]

Answer:

The percent error in his estimate is<u> 16.67%</u>.

Step-by-step explanation:

Given:

Christopher estimates it will take him half an hour to complete his math homework.

He is able to complete it in 25 minutes.

Now, to find the percent error in his estimate.

Time estimates of completing homework = 30 minutes.

Time actual taken to complete homework = 25 minutes.

Error in estimate = Time estimates of completing homework - Time actual taken to complete homework.

Error in estimate = 30 minutes - 25 minutes.

Error in estimate = 5 minutes.

Now, to get the percent error:

$Percent\ error =\frac{Error\ in\ estimate}{Time\ estimates\ of\ completing\ homework} \times 100.$

$Percent\ error=\frac{5}{30} \times 100$

$Percent\ error=\frac{500}{30}$

$Percent\ error=16.67\%.$

Therefore, the percent error in his estimate is 16.67%.
