Math Problem Statement

A frog starts at the origin (0, 0) in a coordinate plane. From any point (x, y), the frog can jump to one of the following points: (x+2, y), (x+3, y), or (x, y+3). The problem asks how many different sequences of jumps the frog can take to move from point (0,0) to point (6,5).

Solution

The text in the image describes a problem where a frog starts at the origin (0, 0) in a coordinate plane. From any point (x,y)(x, y), the frog can jump to one of the following points:

  • (x+2,y)(x+2, y)
  • (x+3,y)(x+3, y)
  • (x,y+3)(x, y+3)

The problem asks how many different sequences of jumps the frog can take to move from point (0,0)(0,0) to point (6,5)(6,5).

Let’s analyze this step by step:

  1. Goal: The frog needs to reach point (6,5)(6,5).

    • It needs to make exactly 66 units of movement in the x-direction.
    • It needs to make exactly 55 units of movement in the y-direction.
  2. X-direction moves: The frog can either jump by 2 or by 3 units in the x-direction, so we need to find all combinations of these moves that sum up to 6.

    • Possible combinations of moves:
      • 3 jumps of 2 units (3x2 = 6)
      • 2 jumps of 3 units (2x3 = 6)
      • 1 jump of 2 units and 1 jump of 3 units (2 + 3 + 1 = 6)
  3. Y-direction moves: The frog can only jump by 3 units in the y-direction. So there
