Find the 7th term of the geometric progression which begins. 2,-6,18
Step-by-step explanation:
Find the rule:
2, -6, 18, ...
To get to -6, multiply by -3.
To get to 18, multiply by -3.
The rule is to multiply by -3.
Find the 7th term:
Multiply 18 by -3.
[tex]-18 \times 3 = -54[/tex]
-54 is the 4th term.
Multiply -54 by-3.
[tex]-54 \times -3 = 162[/tex]
162 is the 5th term.
Multiply 162 by -3.

find area of shaded regions
if the least value of n is 5, which inequality best shows all the possible values of n?
n ≥ 5
n ≤ 5
n < 5
n > 5
Answer:
First option
Step-by-step explanation:
The inequality says greater than or equal to 5. Which means n is greater than or equal to (≥) 5.
It's not the second option because less than or equal to means that n is less than or equal 5, which doesn't check out since 5 is the smallest value of n.
It's not the third option since it says that 5 is greater than n, when we know that one of n's values is 5.
It's not the fourth option since it says that that n is greater than 5, when we know again that one of the values of n is 5.
Your answer is the first option "n ≥ 5."

Answer:
20x + 12 = 4(5x+3)
Step-by-step explanation:
4*5x = 20x and 4*3 = 12
The complete expression will be written as 20x + 12 = 4(5x+3).
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given expression is 20x + 12 = 4(_+_). The value of the missing terms will be calculated as,
4 x ( 5x) = 20x
4 x 3 = 12
20x + 12 = 4(5x+3).

What is an equation of the line that passes through the points (-8, 1) and(7,1)?
please help im giving 20 points to who ever answers it
Answer:
y=1
Step-by-step explanation:
you can use those points to find the slope
use the equation [tex]\frac{y_{1} - y_{2}}{x_{1}-x_{2}}[/tex] then plug in the numbers
so (1-1)/(-8-7) = 0/15 so the slope is zero meaning it is a horizontal line which we can tell logically because the y coordinates of both points are 1.
so if you plug those numbers into the formula y=mx+b where m is slope and b is the y intercept then
you get y=0*x+1
then 0*x is just zero and it goes away so the equation for this line is y=1
Hope this helps! :)

We have Karla who is creating a survey with 6 questions. She suspects that the order of the questions may influence the responses, so she wants to create multiple versions of the survey with the same 6 questions in different orders.
Assume that the she has to arrange the [x] questions. Then the number of unique ways are there to arrange the questions will be x². For [x] = 6, we can write the number of ways to be (6 x 6) = 36.
Therefore, the number of unique ways to arrange the questions will be 36.
