I think the answer might be B.
Dependent. This system is consistent, because the first equation can be rearranged to y+3x=5, which is exactly the same as the second equation, so they don't contradict each other. However, their are infinite number of solutions to the equation y+3x=5, like x=1, y=2; or x=2, y=-1;... so the system is dependent.
Answer:
32 kg
Step-by-step explanation:
1. Convert the fractions to decimals:
2 1/2 = 2.5
2 3/4 = 2.75
2. Set up the equation to show 4 packs of 2.5 kg and 8 packs of 2.75 kg:
4*(2.5) + 8*(2.75)
3. Solve the equation using PEMDAS:
4(2.5) + 8(2.75)
10 + 8(2.75)
10 + 22
32
All statements that are true about the expression is B. and C.
M = (2, 5)
Therefore M' = (-2, 5) [A]
