3x+y=15 <br> 3x-y=15 (using elimination method)
morpeh [17]

Answer:

x = 5

y = 0

Step-by-step explanation:

3x + y = 15

3x -y = 15

Add the two equations;

6x = 30

Inverse operations;

6x = 30

/6        /6

x = 5

Back substitute;

3(5) + y = 15

15 + y = 15

y = 0

b). 1 way to give person 47 their prize

    1 way to give person 19 their prize

Hi there! Can someone help me with this, i need a proper answer, i don't need LINKS or FILES for the explanations.
alexira [117]

Answer:

<u>Using below system of inequalities</u>

  • y > 2x - 3
  • y < x + 1

<u>Following the rules </u>

  • 1. Finding x- and y - intercepts
  • 2. Connecting with dotted line for each as no equal symbol present in any inequality
  • 3. Shade respective regions
  • 4. Solution is the intersection of the shades regions
  • 5. Select any three points in the solution region

<u>Line 1</u>

  • y > 2x - 3
  • x- intercept: y = 0 ⇒ 0 = 2x - 3 ⇒ 2x = 3 ⇒ x = 1.5
  • y - intercept: x = 0 ⇒ y = -3
  • Shaded region is above the line (or to the left)

<u>Line 2</u>

  • y < x + 1
  • x- intercept: y = 0 ⇒ 0 = x + 1 ⇒ x = -1
  • y - intercept: x = 0 ⇒ y = 1
  • Shaded region is below the line (or to the right)

<u>Selected points are:</u>

  • (-1, -1), (1, 1), (2, 2)
