Which is a correct first step in solving 5 - 2x < 8x- 3?
aliina [53]

Answer:

5 < 10x - 3

Step-by-step explanation:

Given:

The given inequality is:

5 - 2x < 8x- 3

The given inequality has variable 'x' on both sides of the inequality.

In order to solve such inequalities, we bring the variables on the same side as the first step in solving for 'x'.

Therefore, we could either add 2x on both sides or add -8x both sides to bring the variable terms on same side.

If we add 2x both sides, we get:

5 - 2x +2x< 8x+2x - 3\\5

So, among all the given options, third option matches the above inequality.

Therefore, the first step in solving the given inequality is 5 < 10x - 3

What is the recursive formula for the sequence 3, -1, -5, -9, -13,...? a1 = 3, an = (an - 1)(-4) a1 = 3, an = (an - 1) – 4 a1 =
Thepotemich [5.8K]

Answer:

a_{n} = a_{n-1} - 4, a_{1} = 3

Step-by-step explanation:

A recursive formula allows us to find the next term in the sequence from the previous term.

note the difference between the terms in the sequence

= - 13 - ( - 9) = - 9 - (- 5) = - 5 - (- 1)  = - 1 - 3 = - 4

That is to obtain any term in the sequence we subtract 4 from the previous term, hence

a_{n} = a_{n-1} - 4, a_{1} = 3
