Answer:
Unit Rate = .692 British Pounds per U.S. Dollar
Step-by-step explanation:
To get pounds per dollar:
pounds/dollar
Divide the number of pounds by the number of dollars
34.6 pounds / 50 U.S. dollars =
34.6/50=0.692
Answer:
9x/4= -9
Mutiply by 4 for both sides.
4(9x/4) cross out 4 and 4, divide by 4 and then becomes 9x. (-9)(4)= -36
9x= -36
Divide by 9 for both sides
9x/9= -36/9
x= -4
You can see the side conditions for the function. We read the x CANNOT be 4. See it?
We evaluate the bottom piece at x = 4. Let's do that.
f(x) = -2x
Let x be 4.
f(4) = -2(4)
f(4) = -8
What about the other piece?
Evaluate the top piece at x = 2.
Let's do that.
f(x) = 3x
Let x be 2.
f(2) = 3(2)
f(2) = 6
Answer: Choice D
Did you follow? It is a piecewise function. Solve it one piece at a time keeping each side condition in mind along the way.
