PLS HELPS!! THIS IS WORTH 200 PTS!! FIRST ONE ASNWERS CORRECTLY, GETS THE BRAINIEST.

A student evaluates the equation [tex]y=2x+5[/tex], using a variety of values for [tex]x[/tex].

After evaluating the equation the student claims: "When [tex]x[/tex] is a positive integer then [tex]y[/tex] is also a positive integer and when [tex]x[/tex] is a negative integer then [tex]y[/tex] is also a negative integer."

What is a value of [tex]x[/tex] that proves that the student's claim is NOT true?

A −3

B −2

C 1

D 2

Respuesta :

Answer:

B) −2

Explanation:

When x is positive then y is positive integer.

When x is negative then y is negative integer.

For Option A

  • y = 2(-3) + 5
  • y = -1              [x is negative so is y]

For Option B

  • y = 2(-2) + 5
  • y = 1               [x is negative but y is positive]

For Option C

  • y = 2(1) + 5
  • y = 7               [x is positive so is y]

For Option D

  • y = 2(2) + 5
  • y = 9                [x is positive so is y]

Answer:

-2

Step-by-step explanation:

As

  • If x is +ve then y is +ve
  • x is -ve then y is -ve

So

here x is negative y must be negative too

Let's check

  • y=2(-2)+5=-4+5=1

y is +ve

So

Option B is wrong
