Ineed with this quick extra points and i’m marking brainlist to step by step explanation

A, B and C

Step-by-step explanation:

To determine which ordered pairs are solutions, substitute the x and y coordinates into the system of equations and if the value equals the right side then the ordered pair is a solution

A (6 , 3 )

(3 × 6) - 3 = 18 - 3 = 15 ← correct, and

(6 × 6) - (2 × 3) = 36 - 6 = 30 ← correct

Hence (6, 3 ) is a solution

B (7, 6 )

(3 × 7) - 6 = 21 - 6 = 15 ← correct, and

(6 × 7) - (2 × 6) = 42 - 12 = 30 ← correct

Hence (7, 6 ) is a solution

C (8, 9 )

(3 × 8) - 9 = 24 - 9 = 15 ← correct, and

(6 × 8) - (2 × 9) = 48 - 18 = 30 ← correct

Hence (8, 9 ) is a solution

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
