Answer:

x=-\frac{4}{9}

Step-by-step explanation:

2x + 1 - 4x = 7x +5

First, take 7x to the left side.

2x + 1 - 4x - 7x = 5

Now take 1 to the right side.

2x - 4x - 7x = 5 - 1

Now combine like terms.

-2x - 7x = 4

-9x = 4

Now divide both sides by -9.

<u>x = - 4/9</u>

Complete the recursive formula of the arithmetic sequence -3, -1, 1, 3,...
Strike441 [17]

Given:

The given arithmetic sequence is:

-3,-1,1,3,...

To find:

The recursive formula of the given arithmetic sequence.

Solution:

We have,

-3,-1,1,3,...

Here, the first term is -3. So, b(1)=-3.

The common difference is:

d=-1-(-3)

d=-1+3

d=2

The recursive formula of an arithmetic sequence is:

b(n)=b(n-1)+d

Where, d is the common difference.

Putting d=2, we get

b(n)=b(n-1)+2

Therefore, the recursive formula of the given arithmetic sequence is b(n)=b(n-1)+2, where b(1)=-3.

-6x + 3y = 9<br>10x + 4y = -6<br>​
Stells [14]

Step-by-step explanation:

(-6x +3y=9 )×4

( 10x+4y)×3

-24x +12y =36

30x+12y= -18

-24x+12y- (30x+12y)= 36-(-18)

-54x = 54

x= -1

by using 10x +4y = -6

apply x= -1

-10+4y= -6

4y= -6 +10

4y=4

y=1

so the answer is x=-1 and y= 1
