Tell whether the ordered pair is a solution to the equation please show how you solve it. (3,2); x+6y = 13

The ordered pair is not a solution as both sides of the equation do not equal each other.  

Step-by-step explanation:

(3,2);  x + 6y = 13

(3) + 6(2) = 13

3 + 12 = 13

15 = 13

a) first term is -4. Multiply by ⅓ to get the next terms

-4, -4/3, -4/9, -4/27

b) Since

|⅓| < 1,

It converges

c) -4/(1 - ⅓)

= -4/⅔

= -4 × 3/2 = -6

sum = -6
