Identify the ordered pairs that are solutions to the linear inequality 5x-y> 4 a. (4,2) b. (5,-2) c.(0,-1) ,1) e. (2,7) f. (8,4)

Plug in each point into the inequality:

5x - y > 4

A. (4,2)

5x - y > 4

5(4) - 2 > 4

20 - 2 > 4

18 > 4        This is a solution because 18 is greater than 4

B. (5, -2)

5x - y > 4

5(5) - (-2) > 4

25 + 2 > 4

27 > 4    This is a solution because 27 is greater than 4

C. (0, -1)

5x - y > 4

5(0) - (-1) > 4

1 > 4     This is not a solution because 1 is not greater than 4

D. (-3,1)

5x - y > 4

5(-3) - 1 > 4

-15 - 1 > 4

-16 > 4   This is not a solution because -16 is not greater than 4

E. (2,7)

5x - y > 4

5(2) - 7 > 4

10 - 7 > 4

3 > 4     This is not a solution because 3 is not greater than 4

F. (8,4)

5x - y > 4

5(8) - 4 > 4

40 - 4 > 4

36 > 4    This is a solution because 36 is greater than 4

A, B, F are solutions to the inequality

answer: a.   one is a factor of every whole number since every number is divisible by itself.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
