Step-by-step explanation:
Given: 
and 
We can solve for f(x) by writing
Let 
Then
We know that f(0) = 0 so we can find the value for k:
Therefore,
Answer:
A=464
B=93
Step-by-step explanation:
A+B=557
A-B=371
Solving the two equations simultaneously gives A=464 and B=93
Answer:
1. 30
2. x<-72
3. 7b=63
4. x=3.2
5. 1/10
Step-by-step explanation:
1. Substitute a for 10
2(150/10)
2*15
30
2. Think of it like a normal equation
x/4<-18
x<-18*4
x<-72
3. 7b=63
4. 2.5x=8
x=3.2
5. 1/5*1/2= 1/10
Money values are usually rounded to the nearest hundredth (2 decimal places).
Thus, this means that her balance can be whole or a terminating decimal to the nearest hundredth.
Therefore, the subset of real numbers that best describes her balance is the set of rational numbers.
