Answer:

x = 20 degrees

Step-by-step explanation:

We know this because angles next to each other in parallelograms add up to 180 degrees, so if we create an equation, 3x + 120 = 180 meaning that 3x = 60, which means that x = 20 degrees.

Answer: 7.29 or 7 1/4 or 29/4 (they're all equal, just rewritten)

Step-by-step explanation:

the angles are equal, so we set the equations to each other and then solve. here's my work:

12k - 9 = 8k + 20

12k (- 8k) - 9 = 8k ( - 8k) + 20

4k - 9 = 20

4k -9 ( + 9) = 20 ( + 9)

4k = 29

k = 7.29 or 7 1/4 or 29/4

Use function notation to write the equation of the line

blondinia [14]

$f(x)=mx+b\to y=mx+b$

We have two points:

$(-3,\ 0);\ (-4,\ 7)$

The point slope form of the line:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute

$m=\dfrac{7-0}{-4-(-3)}=\dfrac{7}{-1}=-7$

$y-0=-7(x-(-3))\\\\y=-7(x+3)\\\\y=-7x-21$

Answer:

$f(x)=-7x-21$
