Given the system of equations 2x – 8y = 0 and –2x + 4y = –8, which statements are true? check all that apply.
1-the x-variable will cancel when adding the system of equations.
2-after adding the system of equations, you get –12y = –8.
3-y = 2
4-x = 8
5-the solution to the system is (2, 8).

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000
