In year 10, the table says the population is 25,000
But if we plugged x = 10 into the equation Lucy got, then,
y = 600x + 25000
y = 600(10) + 25000
y = 6000 + 25000
y = 31000
Lucy's equation says that the population in year x = 10 should be y = 31000 instead of 25000. So this is one way to show that there is an error. The output from the equation isn't matching what the table shows.
Answer:
The commutative property of multiplication states that changing the order of the numbers we are multiplying, does not change the product.
The answer is 2 y= 2 so 3•2=6 6-4=2
