Answer:

f(-2) = 5

Step-by-step explanation:

Step 1: Define

f(x) = -3 + 2x²

f(-2) is x = -2

Step 2: Substitute and Evaluate

f(-2) = -3 + 2(-2)²

f(-2) = -3 + 2(4)

f(-2) = -3 + 8

f(-2) = 5

lions [1.4K]

Answer:

56 bags of a chocolate and a popsicle

Step-by-step explanation:

The first thing is to find the relationship between the number of popsicles and the number of chocolates, which would be the quotient of these:

100/56 = 1.78

Since it does not reach number two, you cannot add 2 popsicles and 2 chocolates, therefore the only way that they contain the same amount is that there is a chocolate and a popsicle, that is to say that a total of 56 bags would come out.
