We have been given a table which lists some of the characteristics of the houses on Katrina’s street.
There are four different relation choices are given. now we have to identify which relationship describes a function.
We know that relations are written usually in ordered pairs (x,y) and a relation can be function only if x-value doesn't repeat.
So we just have to find which of the given ordered pair choices has no repeated x-value in the table.
We see that only "Appraised value" has no repeated value in the table. Hence 4th choice <u>(appraised value, property tax) </u>is the correct answer.
Answer:
A= 320 and B = 280
Step-by-step explanation:
- Amount of sodium from first material = 0.15*A
- Amount of sodium from second material = 0.3*B
Now, if we combine the two chemicals to get a new chemical, which is 22% sodium, then the total amount of combined sodium is amount of sodium from both sources
<=> 0.15A + 0.3B = 0.22*(A+B)
<=> 0.07A - 0.08B = 0 (1)
- But we have a second equation, because we know that A + B = 600 (2)
Solve the system of two equations, (1) and (2), we have:
A= 320 and B = 280
