X= y-2

2x+3y=21
⇒ 2(y-2)+3y=21
⇒ 2y-4+3y= 21 (distributive property)
⇒ (2y+3y)-4= 21 (combine like terms)
⇒ 5y= 21+4
⇒ 5y= 25
⇒ y= 25/5
⇒ y= 5

The final answer is y=5~

Complete the recursive formula of the geometric sequence -0.56\,,-5.6\,,-56\,,-560,...−0.56,−5.6,−56,−560,...Minus, 0, point, 56
pentagon [3]

Answer:

The recursive formula is:

Cn = 10C(n-1)

Step-by-step explanation:

Given the geometric sequence.

-0.56, -5.6, -56, -560, ...

The common ratio is

-5.6/-0.56 = -56/-5.6 = -560/-56 = ... = 10

The recursive formula is easily

Cn = C(n-1) × 10

That is a number is ten times the preceding number.
