Examine this system of equations with the procedure for using the linear combination method. 4x − 9y = 54, 16x − 36y = 208   −16x + 36y = −216 16x − 36y = 208   0 + 0 = −8    0 = −8 Which statements accurately describe this system and its solution? Check all that apply. The linear combination method produced a true statement. The solution to the system is (0, –8). The lines are parallel. There is one solution to the system. There is no solution to the system

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
