What value of x makes the equation true <br> 2 (6x-1) = -38

Anestetic [448]

Answer:

<h3> $\boxed{\bold{\boxed{ \sf{x = - 3}}}}$ </h3>

Step-by-step explanation:

$\sf{2(6x - 1) = - 38}$

Distribute 2 through the parentheses

⇒ $\sf{12x - 2 = - 38}$

Move constant to right hand side and change it's sign

⇒ $\sf{12x = - 38 + 2}$

Calculate

⇒ $\sf{12x = - 36}$

Divide both sides of the equation by 12

⇒ $\sf{ \frac{12x}{12} = \frac{ - 36}{12} }$

Calculate

⇒ $\sf{x = - 3}$

Hope I helped!

Best regards!!

Find the common ratio and an explicit form in each of the following geometric sequences.

Margaret [11]

Answer:

The explicit form is $a_{n}=162(2/3)^{n-1}$

Step-by-step explanation:

The explicit form of a geometric sequence is given by:

$a_{n}=ar^{n-1}$

where an is the nth term, a is the first term of the sequence and r is the common ratio.

In this case:

a=162

The value of the common ratio is obtained by dividing one term by the previous term.

For the first and second terms:

108/162=2/3

For the second and third terms (In order to prove that 2/3 is the common ratio)

72/108=2/3

Therefore:

r=2/3

Replacing a and r in the formula:

$a_{n}=162(2/3)^{n-1}$
