PLZZ HELPP WILL GIVE 100 POINTS Which ordered pairs are solutions to the inequality −2x+y≥−4? Select each correct answer. (0, −5) (1, −2) (3, −1) (0, 1) (−1, 1)

(1, −2)  (0, 1) (−1, 1)

Step-by-step explanation:

−2x+y≥−4

Substitute the points into the inequality and see if it is true

(0, −5)

-2(0) + -5 ≥−4

0-5 ≥−4

-5≥−4

False  not a solution

(1, −2)

-2(1) -2 ≥−4

-2-2 ≥−4

-4≥−4

True    it is a solution

(3, −1)

-2(3) -1 ≥−4

-6 -1 ≥−4

-7 ≥−4

False, not a solution

(0, 1)

-2(0) +1 ≥−4

0+1 ≥−4

1 ≥−4

True it is a solution

(−1, 1)

-2(-1) +1≥−4

2+1≥−4

3≥−4

True it is a solution

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
