Step 1) Combine like terms/variables.

7y and -2y are similar, combine them.
7+(-2y)=5y

3x has no similar variables, so it stays the same

3 and 6 are similar, without variables, combine them.
3+6=9

The final answer is 5y+3x+9

Answer:no, it is not 9y + 3x +9

Step-by-step explanation:

7y + 3x + 3 - 2y + 6

we can re-arrange the expression for easy operation

7y -2y + 3x + 3 + 6

5y + 3x + 9.

Answer:

a) $a_n=2(a_{n-1})$ , where $a_1=5$ .

b) $a_n=5(2)^{n-1}$

Step-by-step explanation:

The given sequence is

$5,10,20,40...$ .

The first term of the sequence is

$a_1=5$

The second term is $a_2=10$

The common ratio for this sequence can be determined using any two consecutive terms in the sequence.

Using the first two terms, the common ratio is

$r=\frac{a_2}{a_1}$

$\Rightarrow r=\frac{10}{5}=2$

a) The recursive rule is given by,

$a_n=r(a_{n-1})$

$a_n=2(a_{n-1})$ , where $a_1=5$ .

b) The explicit rule is given by $a_n=a_1r^{n-1}$

$\Rightarrow a_n=5(2)^{n-1}$
