Answer:
The answer is 0.
Step-by-step explanation:
Let's call the answer a.
We want to find a(2004)
That's an even term. We look at the even terms:
2 2002
4 2000
6 1998
8 1996
10 1994
12 1992
We see that the pattern for the even terms is
"if you add n and a(n), the sum is always 2004."
That is n + a(n) = 2004, or,
a(n) = 2004-n when n is even
So when n = 2004, a(2004) = 2004-2004 = 0

the graph of y=f(x) is shown on the grid
Answer:
look below
Step-by-step explanation:
The equation of graph g(x) = f(-x) as it has been rotated along y-axis and the maximum coordinates of g(x) is (-3, 4).
What is a function?A function can be thought of as output for the given set of inputs. The output is called the dependent variable and the inputs are called the independent variable.
We know when we rotate a function along the y-axis sign of x changes.
Given a function y = f(x) after rotation along y-axis it becomes y = f(-x) = g(x)
and if the given function is odd f(-x) becomes -f(x).
Also given that the maximum point of f(x) = (3, 4).
∴ Function g(x) will have maximum at coordinates (-3, 4).

Which interval would not be used for the stems of a stem-and-leaf plot? 10 100 1 5
Answer:
i think it's 100
Step-by-step explanation:
100 is the interval which would not be used for the stems of a stem-and-leaf plot.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
In a stem-and-leaf plot, the stem is typically the leftmost digits of a number and the leaf is the rightmost digit.
The stem represents the largest common place value of the numbers being plotted.
If the data set is {12, 15, 21, 26, 30, 31, 35, 38}, the stem would be the tens place and the leaf would be the ones place.
The stem values would be 1, 2, 3, and 4.
Therefore, the interval for the stems should be determined by the range of the data set.
Hence, 100 is the interval which would not be used for the stems of a stem-and-leaf plot.

pls hurry the answer is not 36.......Given a * b=ba−ba+ab, find (2*3)×(3*2).
Answer:
36
Step-by-step explanation:
In the above question, we have been given a rule to follow
Given a * b = ba−ba+ab
We are to find (2*3)×(3*2)
Let simplify each bracket first
a * b = ba−ba+ab
2*3, a = 2, b = 3
2*3 = 3×2 - 3×2 + 2×3
= 6 - 6 + 6
= 6
a * b = ba−ba+ab
3*2, a = 3, b = 2
3*2 = 2×3 - 2×3 + 3×2
= 6 - 6 + 6
= 6
(2*3)×(3*2)
= 6 × 6

SO
Write and solve an equation to determine the measure of angle y.
I
The value of y will be 90°. The sum of angle of the two right angle is 180°. The property of the adjacent angle is used.
How can we find the solution to an equation?We do same operations on both the sides so that equality of both expressions doesn't get disturbed.
Solving equations generally means finding the values of the variables used in it for which the considered equation is true.
Sometimes we can find such value, and sometimes it is not possible at all, or sometimes, there are an infinite number of solutions.
The angles subtended by a circle is 360°, then;
The equation is found as;
[tex]\rm 40^0+50^0+x+y+z=360^0 \\\\ x+y+z=270^0[/tex]
The sum of angle of the two right angle is 180°;
x°+40°+50°=180°
x=90°
y+50°+40°=180°
Y=90°
Hence, the value of y will be 90°.

Find the inequality represented by the graph?
Answer:
y > -2/3x + 3
Step-by-step explanation:
Well lets first start with the beginning and look at its features.
Features
- Dashed line
- Shaded up
- negative slope
- y intercept at 3
____________________________________________________________
So if the line is dashed with the shade going up that means the inequality starts like this,
y >
We can tell that the y intercept is at 3 because that the point the line touches the y axis.
So we got y > 3,
To find slope we use the following formula,
[tex]\frac{y^2-y^1}{x^2-x^1}[/tex],
So we can use points (0,3) and (3,1).
1 is y2 and 3 is y1 so 1 - 3 = -2
3 - 0 = 3
Slope: -2/3x
Thus,
the inequality is y > -2/3x + 3.
Hope this helps :)

According to the figure, we have an inequation of the form [tex]y > f(x)[/tex], where [tex]f(x)[/tex] is a linear function.
The linear function can be found by using the point-slope formula:
[tex]y-y_{1} = \left(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\right)\cdot (x-x_{1})[/tex] (1)
If we know that [tex](x_{1}, y_{1}) = (0, 3)[/tex] and [tex](x_{2}, y_{2}) = (3, 1)[/tex], then the linear function is:

a storybook is sold at a discount of 20%. If the discount is $3, what is the selling price of the storybook
Answer:
Step-by-step explanation: the discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.
Answer:
12
Step-by-step explanation:
x = original price
x* 20% = 3
Change to decimal form
x*.2 = 3
Divide each side by .2
x*.2 /.2 = 3/.2
x =15
The original price is 15
Selling price is 15-3 = 12
A coordinate plane with 2 lines drawn. The first line is labeled f(x) and passes through the points (0, negative 2) and (1, 1). The second line is labeled g(x) and passes through the points (negative 4, 0) and (0, 2). The lines intersect at about (2.5, 3.2) How does the slope of g(x) compare to the slope of f(x)? The slope of g(x) is the opposite of the slope of f(x). The slope of g(x) is less than the slope of f(x). The slope of g(x) is greater than the slope of f(x). The slope of g(x) is equal to the slope of f(x). ALSO ITS NOT A NUMBER ANSWER
Answer:
Option B.
Step-by-step explanation:
If a line passing through two points, then the slope of line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that f(x) passing through the points (0,-2) and (1,1). So, slope of f(x) is
[tex]m_1=\dfrac{1-(-2)}{1-0}=1+2=3[/tex]
It is given that g(x) passing through the points (-4,0) and (0,2). So, slope of g(x) is
[tex]m_2=\dfrac{2-0}{0-(-4)}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]
Since, [tex]\dfrac{1}{2}<3[/tex], therefore [tex]m_2<m_1[/tex].
The slope of g(x) is less than the slope of f(x).
Therefore, the correct option is B.
Write the interval {x|1 < x < 3} as an i inequality
and using interval notation.
Answer:
1 < x < 3
(1 , 3)
Step-by-step explanation:
We have been provided with a set that is
{x|1 < x < 3}
We have to write it in both as an inequality and also in the form of interval notation.
The inequality can be found easily by just looking at the given set. It states that the set contains x, such that x is greater than 1 and x is smaller than 3, so the inequality can be written as:
1 < x < 3
To write in interval notation, we use brackets, As both 1 and 3 are not included, we'll use round brackets to show the interval.

47.13 for 17 melons
Answer:
$47.12
Step-by-step explanation:
We know that 1 box has 9 lemons and each box is $24.95. Therefore, 1 lemon costs 24.95/9 dollars. That leads us to know that 17 lemons cost (24.95/9 * 17). Once we plug that into the calculator and round to the nearest hundreth place, we get $47.12.

Step-by-step explanation:
S ≥ 2000 - (S + 178)
S ≥ 2000 - S -178 Add S to both sides,
S + S ≥ 2000 -178
2S ≥ 1822
S ≥ 911 so A ≥ 911 + 178 A≥ 1089 (but the question shown doesn't ask that)
