If a and b are positive, then a-b is positive identify the conclusion of the statement
Elanso [62]

Answer:

The statement is wrong. a-b can be positive but not always.

Step-by-step explanation:

There can be three possible situations that are:

  1. a>b
  2. a<b
  3. a=b

Now taking first condition, the result will be positive because a smaller integer is subtracted from a greater one. Such as 5-2=3

In second condition, the result will be negative because a greater integer is subtracted from smaller one. Such as 2-5= -3

In the third condition, the result will always  be zero because both the integers will cancel each other. Such as 5-5=0

I need to solve this system of equations, how do I do that?<br> 3x-4y=20<br> y=3/4x-5
Paha777 [63]

Answer:

Is is Infinitely many solutions so 0=0

<em><u>Step-by-step explanation:</u></em>

<h3>First we have to rearrange/simplify the equations:</h3>

Equation 1: 4y - 3x = -20

Equation (2):  y - 3x/4  = -5

<h3>Then you remove the fractions by multiplication: </h3>

Multiply equation (2) by 4

<h3>The Equations now look like this: </h3>

Equation 1: 4y - 3x = -20

Equation (2): 4y - 3x = -20

<h3>Solve for y on Equation (2):</h3>

y = <u><em>3x/4 - 5</em></u>

<h3>Then plug in this for the y in Equation 1 and then solve:</h3>

4•(<u><em>3x/4-5</em></u>) - 3x = -20

Therefore the answer leads to:

Infinitely many solutions, 0=0

Hope this helped :')
