Apex
Answer:
x = 3
y = -2
Step-by-step explanation:
x - 2y = 7
y = -x + 1
x - 2y = 7
x - 2 ( -x + 1 ) = 7
3x - 2 = 7
3x = 9
x = 3
y = -x + 1
y = -3 + 1
y = -2
Answer:
Option (3)
Step-by-step explanation:
Explicit formula of the sequence is,

From this explicit formula,
First term of the sequence will be,


Second term of the sequence,

= 13
3rd term of the sequence,

= 31
Sequence formed,
7, 13, 31 ..........
From the given options,
Recursive formula,



= 13



= 39 - 8
= 31
Sequence formed from this recursive formula will be,
7, 13, 31........
Therefore, Option (3) will be the answer.
X^2+2x-5x-10
x(x+2)-5(x+2)
(x-5)(x+2)
