We have,
Looking at the options:
A.
3, 6, 9, 12,... is a geometric sequence with a common ratio of 2.
Each term is found by multiplying the previous term by 2.
B.
2, 3, 5, 9, 17 is not a geometric sequence because there is no constant ratio between terms.
C.
4, 2, 1, 1/2, 1/4 is a geometric sequence with a common ratio of 1/2.
Each term is found by multiplying the previous term by 1/2.
D.
3,-15, -33, -51, -69, is not a geometric sequence because there is no constant ratio between terms.
Therefore,
The series 3, 6, 9, 12,... and 4, 2, 1, 1/2, 1/4 are geometric series.

What are Linear Equations?An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Given data ,
Let the linear function be represented as A
Now , the value of A is
The total cost for the SUV is given by
y₁ = 2,840x + 17,980
And , the total cost for the car is
y₂ = 3,210x + 17,980
when x = 2 years
y₁ = $ 23,660
y₂ = $ 24,400
The cost of the car is greater than cost of the SUV

12. ALGEBRA Sherri Cole found that the 12-ounce can of frozen orange juice
sells for $0.16 less than the 16-ounce can, which is $0.68 less than the
24-ounce can. If the unit price of the 24-ounce can is $0.005 less than the
unit price of the 12-ounce can, which of the three is the best buy based
on the lowest unit price?
Answer:
96 = x
Step-by-step explanation:
I'm going to use cents instead of dollars because I find decimals and fractions to be cumbersome. I assume you meant $.005 instead of 4.005.
Let x denote the price (in cents) of the 12-ounce can. Then the price of the 16-ounce can is (x + 16) cents, and the price of the 24-ounce can is ((x + 16) + 68), or (x + 84) cents.
The unit price (cents per ounce) of the 12-oz can is x/12
The unit price of the 16-oz can is (x + 16)/16
The unit price of the 24-oz can is (x + 84)/24
You are told that, in terms of x,
(x + 84)/24 = x/12 - 0.5
Multiply both sides by 24:
x + 84 = 2x - 12
Solve for x:
96 = x
So the unit prices (in cents per ounce) are:
12 oz: 96/12 = 8 cents/oz
16 oz: 112/16 = 7 cents/oz
24 oz: 180/24 = 7.5 cents/oz
So the 16 ounce can is the best buy based on lowest unit price.
In this exercise we have to use the knowledge of finance to calculate the best price to be offered, in this way:
[tex]12 oz: 96/12 = 8 cents/oz\\16 oz: 112/16 = 7 cents/oz\\24 oz: 180/24 = 7.5 cents/oz[/tex]
Some values should be simplified as they were informed in the statement:
The unit price (cents per ounce) of the 12-oz can is x/12The unit price of the 16-oz can is (x + 16)/16The unit price of the 24-oz can is (x + 84)/24So putting together an equation with these values and terms informed we find that:
[tex](X + 84)/24 = X/12 - 0.5\\X + 84 = 2X - 12\\X=96[/tex]
So with the value of X found it is only necessary to use the previous equations and replace this value.

Answer:
B. 95º
Step-by-step explanation:
Supplementary angles are ones that add up to 180º.
So if angle 1 is 85º, then the equation would be:
(x-the measure of angle 2)
X + 85 = 180
Solve for x:
X + (85-85) = 180-85
X = 95.
Hope this helps! Have a great day!
Answer:
it is B) 95
Step-by-step explanation:
supplementary mean equals to 180. in a triangle problem all the angles should add up to 180. so you take 180 and subtract the number you already have which is 85 and you get 95
Vedant runs around a square park of side 42m, three times. Rehan runs around a rectangular park of length 40m and breadth 18m, five times. Who covers more distance? By how much?
Answer:
Rehan;
76m
Step-by-step explanation:
Distance covered by running around square park :
Perimeter of square = 4s ; s = side length of square
Perimeter = 4 * 42m = 168 m
Total distance covered = 168m * 3 = 504m
Distance covered by running around rectangular park :
Perimeter of rectangle = 2(l + w) ;
Perimeter = 2(40 + 18) = 2(58) = 116 m
Total distance covered = 116m * 5= 580m
580m - 504m = 76m
Rehan covered more distance

7x-3= -24 what is x and how do you find it?
Answer:
x = -3
Step-by-step explanation:
7x - 3 = -24 (Given)
7x - 3 + 3 = -24 + 3 (Added 3 on both sides by using the addition property of equality)
7x = -21 (Simplified)
7x/7 = -21/7 (Divided 7 on both sides by using the division property of equality)
x = -3 (Simplified)
Therefore, x = -3.
Answer:
x= -3
Step-by-step explanation:
You do the opposite.
So,
-24 +3
= -21
-21/ 7
= -3
Therefore, the answer is -3

Micheal has 4 red shirts, 3 green shirts, and 5 blue shirts in his closet. If he randomly selects a shirt, what is the probability he chooses green or red.
a) 1/3
b) 1/4
c) 5/12
d) 7/12
Answer:
D. 7/12
Step-by-step explanation:
First, find the total number of shirts in his closet:
4 + 3 + 5
= 12
Now, find how many are green or red:
4 + 3
= 7
Since 7 out of 12 shirts are green or red, the probability that Micheal chooses green or red is D. 7/12
Determine the intercepts of the line

Dorothy is thinking of two numbers. The sum of the two numbers is 40 and the difference is 6. Write a system of equations and use the elimination method to find the two numbers.
Answer:
x = 23
y = 17
Step-by-step explanation:
x = 1st number
y = 2nd number
System of Equations:
x + y = 40
x - y = 6; this can be used as x = 6+y
6+y + y = 40
6 + 2y = 40
2y = 34
y = 17
x + 17 = 40
x = 23

Step-by-step explanation:
The value of W is inversely proportional to m. If w=8 then m=25, What is m when W is 20?Show me all the steps please?
Answer:
m = 10
Step-by-step explanation:
The values of w is inversely proportional to m
Mathematically the above statement is expressed as:
w ∝ 1/m
w = k × 1/m
w = k/m
Where k is the Proportionality Constant
First step
Solve for k
If w=8 then m=25
w = k/m
8 = k/25
Cross Multiply
k = 25 × 8
k = 200
Second step
what is m when w=20? Show me the steps please
We solve for m
w = k/m
k = 200
20 = 200/m
Cross Multiply
20m = 200
m = 200/20
m = 10
