Answer:

No, (-1,4) is not a solution.

Step-by-step explanation:

This is actually a simple problem...don't overcomplicate it!

All you need to do is plug the values into the equation and solve!

y < 2x + 5

zysi [14]

Answer: Your answer is B.840


Step-by-step explanation:

What you do first is the exponents 10^2 is 100

8.4 x 100 is 840 because when you multiply you move the decimal points the amount of zero's you have to the right but when you divide you do the opposite. You go left the amount of zeros there are.

A 5×6 rectangular grid with unit cells is given. Let A(0, 0) and B(5, 6) be the bottom-left corner and top-right corner, respect
harina [27]

Answer:

462 paths from A to B

Step-by-step explanation:

The question is incomplete. However, a possible question is to determine the number of possible paths on the grid map.

The first step is to represent the grid map itself. (See attachment 1)

From the question, we understand that:

  • Only right movement is allowed in the horizontal direction
  • Only up movement is allowed in the vertical direction

There are a several number of ways to navigate through. However, one possible way is in attachment 2

In attachment 2,

  • R represents the right movement
  • U represents the up movement

And we have:

R = 5     and    U = 6

The number of possible paths (N) is then calculated as:

N = \frac{(N + U)!}{N!U!}

Substitute values for N and U

N = \frac{(5 + 6)!}{5!6!}

N = \frac{11!}{5!6!}

N = \frac{39916800}{120 * 720}

N = \frac{39916800}{86400}

N = 462

<em>Hence, there are 462 possible paths from A to B</em>
