Answer: Correct answer is C -I just took the test
we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.
you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)
now we have:
g(x) = -f(x) = - 4(1/2)x
then the right answer is the third option:
g(x) = -4(1/2)x

Step-by-step explanation:
Assuming we use only one kind of bread, meat and cheese, we have 3, 2, and 3 options for them respectively. Therefore, the total amount of sandwiches we can make is 3 * 2 * 3 = 18.
Answer:
Step-by-step explanation:
4) A photograph costs $20, so the cost of x photographs is 20x.
Similarly, the cost of y prints is $25.
So the total cost is 20x+25y, and this has to be less than or equal to 400, so C.
5) just plug each pair in.
For example for the first option, x=5 and y=10, and since 20(5)+25(10)=100+250. which is less than or equal to 400, it works.
