Which statements are true about the ordered pair (2, 3) and the system of equations?

mel-nik [20]

substitute the ordered pair (2, 3 ) into the 2 equations

(3 × 2 ) + (4 × 3 ) = 6 + 12 = 18 → True

(2 × 2 ) - (2 × 3 ) = 4 - 6 = - 2 → False

Hence the ordered pair (2, 3 ) is not a solution to the system of linear equations.

When (2, 3 ) is substituted into the first equation, the equation is true.

When (2, 3 ) is substituted into the second equation, the equation is false.

Answer:

All the four statements are true , which are -

(A) The subset contains contains of all the outfits that have grey slacks .

(B) The subset contains contains of all the outfits that have grey slacks and red tie .

(C) The subset contains contains of all the outfits that have grey slacks and blue shirt .

(D) The subset contains contains of all the outfits that do not have black slacks .

Step-by-step explanation:

We are given with Outfit 2 , 4 and 6

Outfit 2 - Blue grey red

Outfit 4 - White grey red

Outfit 6 - Black grey red

(A) Since only 2,4, and 6 contain grey slacks, and no other outfit contains grey slacks, those are the subsets that contain grey slacks. Thus , this statement is true .

(B) Just outfits 2, 4, and 6 have grey slacks and a red tie, proving the statement. Other clothes do not include grey slacks and a red tie; they may include a red tie but not both grey slacks and a red tie. Hence , the statement is true .

(C) Since the outfit 2 has grey slacks and a blue shirt, the statement is correct; no other outfit has both grey slacks and a blue shirt. Therefore , this statement is also correct .

(D) The argument is correct since all of the subsets contain grey slacks and no black slacks.

Hence , all the options A , B , C , D are correct and describes the subset .
