Tell whether the ordered pair is a solution of the system of linear inequalities 

Answers: 1 = yes, 2 = no, 3 = yes

Explanation:

1. (3, 7)

y > 6            ⇒  7 > 6  TRUE

y ≤ 2x + 3    ⇒  7 ≤ 2(3) + 3   ⇒  7 ≤ 6 + 3  ⇒  7 ≤ 9   TRUE

Both are true statements so (3, 7) IS a solution

2. (2, 3)

y ≤ 0          ⇒  3 ≤ 0  FALSE

y < 3x - 1

At least one statement is false so (2, 3) is NOT a solution

3. (-2, 1)

y ≥ x - 5      ⇒  1 ≥ -2 - 5   ⇒   1 ≥ -7   TRUE

y > 2x + 7   ⇒  1 > 2(-2) + 7   ⇒  1 > -4 + 7   ⇒  1 > 3   TRUE

Both are true statements so (-2, 1) IS a solution

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
