Answer: B, E, and F.
Step-by-step explanation: -$300 means negative 300 which is not a gain, it is a loss as negative numbers are losses. So A is wrong. +400 indeed is a gain as it is a positive and has an addition sign in front of it Using this knowledge we can see that besides B, only E and F are correct.

(P13.2
Xavier starts with the integer -10 and multiplies it by a negative integer. Mark the statements below as true or false. If false, explain
why to the right of the statement.
a. The resulting product cannot be greater than-10.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
b. The resulting product must be greater than 0.
c. The resulting product cannot be less than 10.
Answer:
a. The resulting product cannot be greater than-10. (False)
b. The resulting product must be greater than 0. (True)
c. The resulting product cannot be less than 10. (True)
Step-by-step explanation:
Explaining Statement (a):
The integer that is given is -10,
Let it will b multiplied with another negative integers let say (-1). Starting with the smallest one in order to clarify all statement.
So, if the resultant product is represented by x, So:
x = (-10)(-1)
Using the sign Multiplication rule which is {(-)*(-)} = +
x = 10
While looking at the result It is greater than -10 because 10 is greater than -10 (So, First Statement is False)\Similarly, the resulting product is greater than 0 because 10 is greater than 0 (So, 2nd statement is true)At the end, the minimum integer choose to multiply with the -10 will be -1. It neither be -0.5 because -0.5 is not an integer. Hence answer will never ever be less than 10. (Last statement is True)Complete the following sentences based on the graph of the function.
