The elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to eliminate the yuvarlable, and what is the solution for this system? x+3y=42 2x-y= 14 ОА. Multiply the second equation by-3. The solution is x= 12, y=9. Multiply the second equation by-2. The solution is x=12, y=10. B. Ос. Multiply the second equation by 2. The solution is x= 15, y=9. D. Multiply the second equation by 3. The solution is x= 12, y=10.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

x/3-10=8

x/3=18

x=48

246

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
