The formula is y= k x where k is the constant of variation, so plug a coordinate in the formula to find value of k, lets get (3,12) you have 12 = 3k, then k = 4, if you get (9,36) then you have 36 = 9k where k = 4

Answer:

The value of x = -13

Step-by-step explanation:

Given the expression

$\frac{0.2x+1}{2}=-0.8$

Multiply both sides by 2

$\frac{2\left(0.2x+1\right)}{2}=2\left(-0.8\right)$

simplify

$0.2x+1=-1.6$

Subtract 1 from both sides

$0.2x+1-1=-1.6-1$

Simplify

$0.2x=-2.6$

Divide both sides by 0.2

$\frac{0.2x}{0.2}=\frac{-2.6}{0.2}$

Simplify

$x=-13$

Therefore, the value of x = -13

Answer:

x = 4

Step-by-step explanation:

All of the sides are the same so every angle is 17x-8.

Every triangle adds up to 180 degrees.

3(17x-8)=180

51x-24=180

+24 +24

51x=204

x= 4
