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.

b. The resulting product must be greater than 0.
c. The resulting product cannot be less than 10.

Respuesta :

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)
