Answer:
Rational
Step-by-step explanation:
The square root of 25 is 5, which is a rational number.
The place value 8 in 281,480,100 is the 10th. And it is the same way in the other problem. How you get your answer is by counting like this EX: 1, 10, 100, 1,000, 10,000, 100,000... And so on.
A) The membership cost starts at $23 and it adds $6 every year. The 23 would be your b and the 6 would be your slope, m, in the form y=mx+b.
y=6x+23
This equation means that you're starting at 23 dollars and adding 6 dollars with every x you add.
B) 2009-1995=14 This means that there's 14 years that the cost increased. 14*6=$84 The membership cost increased by anther $84 over the 14 years. You have to add 84 to 23 to find your total=$107.
C) Set $85 equal to 6x+23
85=6x+23
6x=62
x≈10
10 years later the cost will be $85.
1995+10=2005
10(3+10с)
This expression has a common factor of 10
