5.
y = -x - 1
3x + y = 5
Substitute

(3,-4)

Step-by-step explanation:

3x+(first equation)=5

3x+(-x-1)=5

2x-1=5

x=3, solve for y;

y=-3-1, y=-4

1 is c

2 is a

3 is a

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
