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:

Step-by-step explanation:
From the question we are told that
Six wire are attached to a circuit board
Generally using multiplication rule
Let number of possible sequence be given as S
Mathematically

Therefore
Number of possible sequence 
Answer:
x = 15
Step-by-step explanation:
The two angles add to a straight line, so they add to 180
6x-5 + 6x+5 = 180
Combine like terms
12x = 180
Divide by 12
12x/12 =180/12
x =15
A is a good answer because yes
Answer:
135
Step-by-step explanation: Multiply 160 by 0.85(for 85%) and you get 135
