The sum of the series is 5, the correct option is D.
What is a Geometric Series?A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.
The summation of the series is obtained by the expression k²-1
For [tex]\sum_{1\to 3} k = k^2 -3[/tex]
By adding the terms of the series
The terms of the series from 1 to 3 is -2, 1, 6
On adding the terms
=> -2 + 1 +6

Ciana wants to buy a shirt that regularly cost 30$.It is on sale for 40$ off. How much is Ciana saving on the shirt?Please help ASAP
Answer:
I think you meant 40% off. If so...
Step-by-step explanation:
First, you have to turn 40 into a decimal - .40.
Then you multiply 30*.40 and get 12.
Subtract 12 from 30 since you are saving 12 dollars.
This means you spend $18 and saved $12.
So, your final answer would be $12.

The values in the table represent a linear function. How does the value of y change in relation to a change in the
value of x?
A)
for every change in x by -6, y changes by 4
B)
for every change in x by 6, y changes by -4
for every change in x by -4, y changes by-6
D)
for every change in x by-6, y changes by -4
Answer:
For every change in x by -6, there is a corresponding change in y by -4
Step-by-step explanation:
Given
x ---- y
9 --- 4
3 --- 0
-3 -- -4
-9 -- -8
Required
Determine the rate of change
To do this, we simply get an expression for the slope.
Take any two corresponding x and y values.
[tex](x_1,y_1)= (9,4)[/tex]
[tex](x_2,y_2)= (3,0)[/tex]
The slope (m) is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{0 - 4}{3 - 9}[/tex]
[tex]m = \frac{- 4}{-6}[/tex]
This can then be represented as:
[tex]\frac{y_2 - y_1}{x_2 - x_1} = \frac{- 4}{-6}[/tex]
It means that:
For every change in x by -6, there is a corresponding change in y by -4

Which description best compares the graphs of the two functions below I ready
Answer:
Some of your pic is cut off so it's difficult to give the exact answer. But if you plot the points from the table you get that the equation for that set of data is linear and is y = 1/3x -2. This tells me that the y-intercepts are the same for both equations, so your answer is not the first or the third. Because the slope of the function A is 3 and for B is 1/3, the line for function A is steeper, the second of your choices above.
Y=3x-1 is dilated by a scale factor of 4 and center at the origin what is the equation that represents the image of the line after the dilation
Answer: x=1/3y+1/3
Step-by-step explanation: Step 1: Flip the equation. 3x−1=y Step 2: Add 1 to both sides. 3x−1+1=y+1/3x=y+1 Step 3: Divide both sides by 3. 3x/3 = y+1/3 x= 1/3 y+ 1/3

In the given figure ΔEGH ≈ ΔEDF (similar triangle) thus, the measure of the GH will be 47.
What is symmetry?If two figures look an exact shape but their size could be small or big then both figures are called similar figures.
For example, a square with a side of 10 cm and another with a side of 20 cm both square will be similar.
When anything has identical pieces facing one another or revolving around an axis, it is said to be symmetrical.
The given triangles ΔEGH ≈ ΔEDF therefore, the ratio of the corresponding sides must be the same.
EH/EF = GH/DF
EH/(EH + HF) = (3x - 4)/(9x - 59)
EH/(2EH) = (3x - 4)/(9x - 59)
1/2 = (3x - 4)/(9x - 59)
9x - 59 = 2(3x - 4)
9x - 59 = 6x - 8
9x - 6x = -8 + 59
3x = 51
x = 17
Therefore,GH = 3(17) - 4 = 47
Hence "In the given figure ΔEGH ≈ ΔEDF (similar triangle) thus, the measure of the GH will be 47".

Two points, a and b, are graphed on the number line below. Maynard says there is not
enough information to write an inequality statement comparing a and b. Which statement
explains whether or not Maynard is correct?
Answer:b
Step-by-step explanation:
Maynard is incorrect on the number line a is to the left of b thus a < b can be represented thus option (A) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given number line,
If a number is going to the left of a number line then it will become lower and lower.
Since a is on the left of b so a < b.
It is also obtained that a is less than 0 so it will be negative while b will be positive since all negative value is less than positive thus a < b will be correct.
Hence "Maynard is mistaken since an is to the left of b on the number line, which can be expressed as a b".
