Find the value of f(-9).
Answer:
f(- 9) = 2
Step-by-step explanation:
f(- 9) is asking for the value of y when x = - 9
Locate x = - 9 on the x- axis
Then go vertically up to meet the graph at (- 9, 2 )
Thus when x = - 9, y = 2 , that is
f(- 9) = 2

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the function be f ( x ) = A
Now , Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero
So , the function which represents the graph will be
f ( x ) = 1 / ( x - 2 )² be equation (1)
And , the graph of the function is given below
Hence , the equation is f ( x ) = 1 / ( x - 2 )²

Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100
Answer:
There are no solutions whenever k=4,5mod9.
This holds since it is not difficult to verify that for every integer n, we have n3=0,±1mod9.
Up till this year, there were just two values for k in the range 1..100 for which it was not known if there were a solution. These values are k=33,42.
Both values are now known to have solutions. See 42 is the answer to the question “

Step-by-step explanation:
The requirement that side lengths be greater than 0 means that ...
y > x > 0
y > z > 0
Then possible values for x and z are 1, 2, 3, and possible values for y are 3, 4, 5, 6, 7.
When we list the possibilities, and exclude those that do not give isosceles triangles, we find the values of {a, b, c} can be those listed above.

To make an international call, there is a flat fee of $3.15 plus $0.05 for every minute that you talk. If you were charged $5.10 for making an international call, for how many minutes did you talk?
Answer:
39 minutes
Step-by-step explanation:
I used a calculator
Answer:
39 minutes
Step-by-step explanation:
a = 0.05m + 3.15 where a=the total charged, m=the amount of minutes
5.10 = 0.05m + 3.15
1.95 = 0.05m
1.95/0.05 = m
m = 39 minutes
2. A farmer earns $4 for each bushel of corn he sells. The equation y = 4x can be used to
represent this situation, where x is the number of bushels of corn sold and y is the total amount
earned. What is the range that would represent this situation if no more than 1,000 bushels of
corn are sold?
Answer:
A
Step-by-step explanation:
Since x represents the bushels of corn that will be our variable. X (our number of bushels) is greater than or equal to zero, but x is less than or equal to 1000 since it is no greater than 1,000/
Here are two spheres, with

area of the larger sphere?
4.6 cm
3 cm
A) 417 cm2
C) 817 cm2
B) 547 cm2
D) 121.57 cm2
Given:
Radii of two spheres are 3 cm and 4.5 cm respectively.
Surface area of the smaller sphere is 367 cm.
To find:
The surface area of the larger sphere.
Solution:
We know that, area of similar spheres is proportional to the square of there radii.
[tex]\dfrac{A_1}{A_2}=\dfrac{(r_1)^2}{(r_2)^2}[/tex]
On substituting the values, we get
[tex]\dfrac{367}{A_2}=\dfrac{(3)^2}{(4.5)^2}[/tex]
[tex]\dfrac{367}{A_2}=\dfrac{9}{20.25}[/tex]
On cross multiplication, we get
[tex](367)(20.25)=9A_2[/tex]
[tex]7431.75=9A_2[/tex]
Divide both sides by 9.
[tex]\dfrac{7431.75}{9}=A_2[/tex]
[tex]825.75 =A_2[/tex]
Therefore, the area of larger sphere is 825.75 cm².

Raul opened a savings account with $4800. Each week, d, Raul pays the dog sitter $20 from his savings account. Write a function, f(d) , that is equal to the amount of money in the account after Raul pays the dog sitter each week.
Answer:
The function is: f(d)=4800-20d
Step-by-step explanation:
With the information provided, the function to calculate the amount of money in the account after Raul pays the dog sitter each week would be equal to the amount he used to open the savings account minus the result of multiplying the amount he pays the dog sitter each week for the number of weeks:
f(d)=4800-20d
According to this, the answer is that the function is: f(d)=4800-20d.

Find the y-intercept of the following function:
[tex]2x - 4y = 9[/tex]
Hi there!
[tex]\large\boxed{0, -\frac{9}{4} }[/tex]
2x - 4y = 9
Begin by isolating the y variable by moving 2x to the right-hand side of the equation. (Subtract 2x from both sides):
2x - 2x - 4y = 9 - 2x
-4y = 9 - 2x
Further isolate by dividing both sides by -4:
-4y / (-4) = (9 - 2x) / (-4)
y = -9/4 - 2x/(-4)
Simplify further:
y = -9/4 + 1/2x
y = 1/2x - 9/4
The "b" value is the y-intercept, therefore:
x = 0 at y = -9/4
Answer:
[tex]\huge\boxed{(0, \frac{-9}{4} )}[/tex]
Step-by-step explanation:
2x - 4y = 9
To find the y-intercept, set the x value in the equation to 0.
Rewrite
2(0) - 4y = 9
Simplify
-4y = 9
Multiply both sides of the equation by -1
4y = 9
Divide both sides of the equation by 4
y = -9/4
y = -4.5
Now that we know the y intercept, we can find the coordinate.
(x, y)
Substitute
(0, [tex]\frac{-9}{4}[/tex])

Answer:
Rotation of 180° about the origin, translation of (x + 10, y − 2), and reflection across y = −6
Step-by-step explanation:
The sequence of transformations that will map figure H onto figure H' is the rotation of 180° about the origin, translation of (x + 10, y − 2), and reflection across y = −6.
Given :
Points of Hexagon H -- (2,2), (2,6), (6,7), (8,6), (8,2), (6,1)
Points of Hexagon H' -- (2,-8), (2,-4), (4,-3), (8,-4), (8,-8), (4,-9)
The following steps can be used to transform the hexagon H into hexagon H':
Step 1 - Translate the hexagon in the positive x-axis direction by a factor of 10.
Step 2 - Translate the graph obtained in the above step by factor 2 in the downward direction.
Step 3 - Now, rotate the graph obtained in the above step 180 degrees about the origin.
Step 4 - Then take the reflection of the graph obtained in the above step about y = -6. The resulting graph shows the graph of Hexagon H'.
Therefore, the correct option is B).
