We know: The sum of the angles of each quadrilateral is 360°.

Therefore we have equation:

x + 3x + 4x + 2x = 360

10x = 360 |:10

x = 36

What are two consecutive integers whose sum is -97

zimovet [89]

Answer:

-48 and -49

Step-by-step explanation:

n + n + 1 = -97

2n + 1 = -97

2n + 1 - 1 = -97 - 1

2n = -98

2n/2 = -98/2

n = -49

-49 + 1 = -48

-49, -48

Find the slope of the line that passes through the points (0,-11) and (8,-8).

Korolek [52]

To find the slope of a line, we can use the following formula:

$\displaystyle \large{m = \frac{y_2 - y_1}{x_2 - x_1} }$

m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.

Let these be the following:

$\displaystyle \large{(x_1,y_1) = (0, - 11)} \\ \displaystyle \large{(x_2,y_2) = (8, - 8)}$

Substitute the points in formula:

$\displaystyle \large{m = \frac{ - 8 -( - 11)}{ 8 - 0} }$

Negative multiply negative always come out as positive.

$\displaystyle \large{m = \frac{ - 8 + 11}{ 8 - 0} } \\ \displaystyle \large{m = \frac{ 3}{ 8 } } \\$

Since m stands for slope, we can say that:

$\displaystyle \large \boxed{ \tt{slope = \frac{3}{8} }}$
