Answer:
C
Step-by-step explanation:
The common ratio (r) can be found as
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{9}{6}[/tex] = [tex]\frac{3}{2}[/tex] → C
The common ratio of the geometric sequence is c. r = 3/2.
To determine the common ratio of a geometric sequence, we need to find the ratio between consecutive terms.
In the given sequence: 6, 9, 27 / 2, 81 / 4, ...
To find the ratio between consecutive terms, we divide each term by its preceding term.
9 / 6 = 3 / 2
(27 / 2) / 9 = 3 / 2
(81 /4 ) / (27 / 2) = 3 / 2
We observe that the ratio between consecutive terms is always 3 / 2.
Therefore, the common ratio of the geometric sequence is c. r = 3/2.

graph a line that contains the point (3,-6) and has slope of -1/2
Answer:
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y intercept
Since, m = -[tex]\frac{1}{2}[/tex]
Equation of the line will be,
y = [tex]-\frac{1}{2}x+b[/tex]
Since, a point (3, -6) lies on the line,
-6 = [tex]-\frac{3}{2}+b[/tex]
b = -6 + 1.5
b = -4.5
Equation of the line will be,
[tex]y=-\frac{x}{2}-\frac{9}{2}[/tex]
Table for the points on the graph,
x -4 -3 -2 -1 0
y -2.5 -3 -3.5 -4 -4.5
Plot these points and join them to get the graph of a line.

A service center charges a fee of x dollars for an oil change plus y dollars per quart of oil used. A sample of its sales record is shown.
A table shows the oil tank size in quarts and total cost for two customers. Customer A: Oil tank size, 5 quarts. Total cost, 22.45 dollars. Customer B: Oil tank size, 7 quarts. Total cost, 25.45 dollars.
Write a system of linear equations that represents this situation.
Equation for customer A:
____=22.45$
Equation for customer B:
___=25.45$
Question 2
Find the fee and cost per quart of oil.
$ fee?
$ per quart of oil?
Answer:
Fee - $14.95, and $1.5 per quart of oilStep-by-step explanation:
Equation for customer A:
x + 5y =22.45$Equation for customer B:
x + 7y=25.45$Subtract the first equation from the second and solve for y:
x + 7y - x - 5y = 25.45 - 22.452y = 3y = 3/2y = 1.5Find x by substituting the value of y:
x + 5*1.5 = 22.45x = 22.45 - 7.5x = 14.95The point where the graphs of two equations intersect has y-coordinate 2. One equation is y=−3x+5 . Complete the other equation in the form y=mx+b if its graph has a slope of 1.
Answer:
y = x + 1
Step-by-step explanation:
y = -3x + 5
Let y = 2
2 = -3x +5
-3 = -3x
x = 1
(1, 2)
y = mx + b
y = 1x + b
2 = 1 + b
b = 1
Therefor, the other one is, y = x + 1

Answer:
Step-by-step explanation:
p-1=5p+3p-8
7=7p
p=1
Answer:
p = 1
Step-by-step explanation:
[tex]p-1 = 5p + 3p - 8[/tex]
combine like terms on the right side
[tex]p - 1 = 8p - 8[/tex]
subtract 8p from both sides
[tex]-7p - 1 = -8[/tex]
add 1 to both sides
[tex]-7p = -7[/tex]
divide both sides by -7

The theoretical probability of spinning a 1 is
Answer:
Step-by-step explanation:
That depends on how many sections there are. If there are 2 sections, then it will be a 50/50 chance it lands on 1 if there are 3 sections then it would be 1/3 or for 4, 1/4, and for 5, 1/5, etc.
The theoretical probability of spinning a 1 is 1/4.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Theoretical probability is the probability that we find through the theoretical approach without doing the experiment.
Total number of sections that the spinner has = 4
Number of sections numbered 1 = 1
Probability of spinning a 1 = 1/4
Hence the required probability = 1/4.

1. A rectangular garden has a perimeter of
120 feet. The length of the garden is 24 feet
greater than twice the width. The system of
linear equations 21 +2w = 120 and 1-2w = 24
represents this situation, where I is the
length of the garden and wis the width. Find
the length and width of the garden.
Answer:
Length: 48
Width: 12
Step-by-step explanation:
Substition
l - 2w = 24
I = 60 - w
60 - w - 2w = 24
60 - 3w = 24
-3w = -36
w = 12
Substitute it into the equation to get the length.
l = 60 - 12
l = 48
