Answer:
-2.6, -1.7, -0.81, 0.24, 1.89
Step-by-step explanation:
No, the longest side must be less than the sum of the smaller sides or else they won't connect (try it yourself with straw or something)
40+30>120
70>120
false, therfor they canonot be a triangle
Answer:
x= -2/3y-4
Step-by-step explanation:
3x+2y=-12
3x+2y-2y= -2y-12
3x=-2y-12
3x/3= -2y/3-12/3
x= -2/3y-4
So hmmm recall the "inscribed angle theorem", notice the first picture
thus, check the second picture, recall, a flat line line AOD is 180° wide
Example of linear equation:

Let's have the linear equation;

<h3 /><h3>Put x=1</h3>


<h3>Put x=2</h3>


<h3>Put x=3</h3>
