Answer:

  • (2, -2)

Step-by-step explanation:

<u>Given</u>

  • y = x - 4
  • 2x + y = 2

<u>Solving by substitution</u>

  • 2x + (x - 4) = 2
  • 3x - 4 = 2
  • 3x = 6
  • x = 2

<u>Then finding y</u>

  • y = x - 4
  • y = 2 - 4
  • y = -2

Intersection point is (2, -2)

Serhud [2]

Answer:

3.75 cubic inches

Step-by-step explanation:

since the box holds 2 layers of 15 cubes

length contains 5 cubes= 5x1/2 inches=2.5 inches

breadth contains 3 cubes=3x1/2inches=1.5 inches

height contains 2 cubes=2x1/2inches=1.0 inches

Volume=2.5x1.5x1.0=3.75 cubic inches
