Answer:

x = 21 The angles are 85°, 58°, 69°, and 148°

Step-by-step explanation:

The sum of the interior angles of a 4 sided figure formula :

Sum of the interiors = (n - 2) 180°

Sum of the interiors = (4 - 2) 180

Sum of the interiors = (2)180° = 360°

Now : 85° + (x + 37)° + 69° + (6x + 22)° = 360°

213 + 7x = 360

7x = 360 - 213

7x = 147

x = 21 the angles are 85°, (21 + 37)° = 58°; 69°; (6·21 +22)°= 148°

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, the

Kazeer [188]

Answer:

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

$b=5$

Step-by-step explanation:

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-6,\:6\right),\:\left(x_2,\:y_2\right)=\left(12,\:3\right)$

$m=\frac{3-6}{12-\left(-6\right)}$

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

As the equation in point-slope form

$y-y_1=m\left(x-x_1\right)$

Here:

m is the slope and

$\left(x_1,\:y_1\right)$ is a point on the line

using $m=-\frac{1}{6}$ and $\left(x_1,\:y_1\right)=\left(-6,\:6\right)$ then

$y-6=-\frac{1}{6}\left(x-\left(-6\right)\right)$

$-\frac{1}{6}\left(x-\left(-6\right)\right)=y-6$

$\mathrm{Multiply\:both\:sides\:by\:}-6$

$\left(-\frac{1}{6}\left(x-\left(-6\right)\right)\right)\left(-6\right)=y\left(-6\right)-6\left(-6\right)$

$x+6=-6y+36$

$x+6-36=-6y$

$x-30=-6y$

$\frac{x-30}{-6}=\frac{-6y}{-6}\:$

$y=\frac{-1}{6}x+5$

Thus

$y=\frac{-1}{6}x+5$

comparing the equation with the slope-intercept form

$y=mx+b$

so,

$y=mx+b$

$y=\frac{-1}{6}x+5$

Therefore,

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

$b=5$

TRUE OR FALSE!!it is possible for a system of linear equations to have no solution

frez [133]

True
if the lines are paralell, there is no intersection and therefor no solution

example
y=3x+4
and
y=3x+10
or

3x+2y=4 and
3x+2y=9

true
