Answer:
The total earnings of Carey in t tours is 12 t - 2 .
Step-by-step explanation:
For each hour he babysits, Anderson earns $1 more than half of Carey's hourly rate. Anderson earns $6 per hour. Which equation can be used to solve for Carey's hourly rate, c? 18 + ?T = 24 What number should be the coefficient of t?
Anderson earns $1 more than half of Carey's hourly rate.
Anderson hourly rate = $ 6
Let Carey's hourly rate is p. Let the time is t hours.
So, Anderson rate is
Answer:
The answer is 1.
Step-by-step explanation:
9^15 = 205891132094649
205891132094649(1/205891132094649
)
Cancel the common factor of "205891132094649
"
You are left with 1.
Answer:
Consider f: N → N defined by f(0)=0 and f(n)=n-1 for all n>0.
Step-by-step explanation:
First we will prove that f is surjective. Let y∈N be any natural number. Define x as the number x=y+1. Then x∈N, and f(x)=x-1=(y+1)-1=y. We conclude that f is surjective.
However, f is not injective. Take x1=0 and x2=1. Then x1≠x2 but f(x1)=0 and f(x2)=x2-1=1-1=0. We have shown that there are two natural numbers x1,x2 such that x1≠x2 but f(x1)=f(x2), that is, f is not injective.
Note:
If 0∉N in your definition of natural numbers, the same reasoning works with the function f: N → N defined by f(1)=1 and f(n)=n-1 for all n>1. The only difference is that you consider x1=1, x2=2 for the injectivity.
