Each piece is defined over some (limited) domain. When you are evaluating or graphing a piecewise function, you only evaluate or graph the function whose domain includes the variable value of interest.
Answer:
5/3
Step-by-step explanation:
2x+3=5x-2
Subtract 2x from both sides
3=3x-2
Add 2
5=3x
Divide by three
5/3=x
Answer:
{9, 7, 5, 3, 1}
Step-by-step explanation:
All you do is plus in each domain value in for the x and you get the range every time.
-2(-2)+5
-2(-1)+5
-2(0)+5
-2(1)+5
-2(2)+5
1euro = 1.3687 USD
So 150 Euros = 150*1.3687 USD
=<span>205.305 USD
So he spent $205.305 USD on his trip.
He started off with $250 so to find the amount left we just take
250 - 205.305
= $44.695
Or 44 dollars and 69.5 cents. It's a weirdly exact amount, sure, but the question had a very precise exchange rate, so we'll assume this is fine. </span>
