What is the 4th term in the sequence b(n)=1(-2)^n-1

mel-nik [20]

$b(n)=1(-2)^n-1$

When n = 4,
$b(4)=1(-2)^4-1$

$b(4)=16-1$

$b(4)=15$

-------------------------------------------------------------

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

When n = 4
$b(4)=1(-2)^{4-1}$

$b(4)=1(-2)^3$

$b(4)=1(-8)$

$b(4)=-8$

12p + 7 > 139 greater or less than

bazaltina [42]

Answer:

$\Huge \boxed{p>11}$

Step-by-step explanation:

First, subtract by 7 both sides of equation.

$\displaystyle 12p+7-7>139-7$

Solve.

$\displaystyle 139-7=132$

$12p>132$

Then, divide by 12 both sides of equation.

$\displaystyle \frac{12p}{12}=\frac{132}{12}$

Solve to find the answer.

$\displaystyle 132\div12=11$

$\huge \boxed{p>11}$ , which is our answer.

How would you solve y+1= -4x ? with a step by step solution

polet [3.4K]

Answer:

There are an infinite number of solutions.

Step-by-step explanation:

An equation with 2 unknowns give an infinite amount of solutions, here is just one of the many:

Let y= 3 ( y can be any number)

(3) + 1 = -4x

4 = -4x

x = -4/4

x= -1

(x;y) = (-1;3)

Generally x and y can be any number, just let x or y be any number, then find the other variable based on the value of the number u assumed.
