Matrices.

It sounds like "elementary transformation method" refers to Gauss-Jordan elimination.

Start with the augmented matrix,

• Add (-1)(row 1) to row 2, and (-3)(row 1) to 2(row 3). In other words,

-(2, 3, 1, 1, 0, 0) + (2, 8, 1, 0, 1, 0) = (0, 5, 0, -1, 1, 0)

-3 (2, 3, 1, 1, 0, 0) + 2 (3, 7, 2, 0, 0, 1) = (0, 5, 1, -3, 0, 2)

I'll omit these details in the next several steps. The augmented matrix then transforms to

• Add (-1)(row 2) to row 3:

• Add (-1)(row 3) to row 1:

• Add (-3)(row 2) to 5(row 1):

• Multiply row 1 by 1/10 and row 2 by 1/5:

We're done, and we find that

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
