Hi I need answer please. I will mark brainliest who can answer thankyou...​
DochEvi [55]

Answer:

  • a) (0,0), (-4, 1), (-1,2)
  • b) None

Step-by-step explanation:

  • <em>There are two ways of solving similar problems. One- substitute x and y with respective coordinates and verify if the inequalities are correct. Two- graph the lines and see if the points are in the intersection zones.</em>
  • <em>We'll go with the first method. </em>
  • <em>Remember both inequalities should be correct for the same point to accept it as a solution.</em>

<u>Given points </u>

  • (0,0), (-4,1), (-1,2)
<h3>a) <u>The system of inequalities</u></h3>
  • y > x - 1
  • y < -1/2x + 2

<u>Point (0,0)</u>

  • 0 > 0 - 1 = -1 correct
  • 0 < -1/2(0) + 2 = 2 - correct
  • Yes

<u>Point (-4,1)</u>

  • 1 > -4 - 1 = -5 - correct
  • 1 < -1/2(-4) + 2 = 4 - correct
  • Yes

<u>Point (-1,2)</u>

  • 2 > -1 - 1= -2 - correct
  • 2 < -1/2(-1) + 2 = 2.5 - correct
  • Yes
<h3>b) <u>The system of inequalities</u></h3>
  • x - 2y ≥ 4
  • 2x - y ≥ -1

<u>Point (0, 0)</u>

  • 0 - 2(0) = 0 ≥ 4 - incorrect
  • 2(0) - 0 = 0  ≥ -1 - correct
  • No

<u>Point (-4, 1)</u>

  • -4 - 2(1) = - 6 ≥ 4 - incorrect
  • 2(-4) - 1 = - 9 ≥ -1  - correct
  • No

<u>Point (-1,2)</u>

  • -1 - 2(2) = -5  ≥ 4 - incorrect
  • 2(-1) - 2 = - 4 ≥ -1  - correct
  • No
