Write the solution set of the given homogeneous system in parametric vector form. 2 x 1 plus 2 x 2 plus 4 x 3 equals 0 where the solution set is xequalsleft bracket start 3 by 1 matrix 1st row 1st column x 1 2nd row 1st column x 2 3rd row 1st column x 3 endmatrix right bracket

answer: idk

step-by-step explanation:

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.

v=1788.75

step-by-step explanation:

i belive that is the answer
