Answer:
(x + 9)(x - 9)
Step-by-step explanation:
Apply the Difference of Two Squares formula: x² - y² = (x + y)(x - y)
Rewrite 81 at 9²
⇒ x² - 81 = x² - 9² = (x + 9)(x - 9)
Answer:

A) -64
B) -16
C) 16
D) 64

Step-by-step explanation:
Well, an example of a perfect square trinomial would look like is:
[tex]a^2-2ab+b^2[/tex] or [tex]a^2+2ab+b^2[/tex]
So since we already know what [tex]a^2[/tex] is and what [tex]2ab[/tex] is we just have to find [tex]b^2[/tex]
However, we would use the [tex]a^2-2ab+b^2[/tex] formula to solve this since we have a subtraction sign

Answers
Answer:
They are not similar
Step-by-step explanation:
To see whether the triangles are similar or not we can compare their side lengths:
AB = 24
AX = 6
AX/AB = 1/4 is the ratio now let's compare this to AY/AC
AY/AC = 10/25 if we simplify this the result will be 2/5 as we can see the side lengths are not proportional so the triangles are not similar.
Joe bought 15 items for $135. If the 15 items consisted of notebooks that cost $4.50 each and calculators that cost $12.00 each, how many of each did he buy?
Answers
n + c = 15
4.5n + 12c = 135
c = 15 - n
12c = 180 - 12n
180 - 12n + 4.5n = 135
-7.5n = - 45
15n = 90
notebook = 6
6 + c = 15
calculator = 9
7. Arrival of the Normandy Train
Claude is waiting to meet the train from Normandy at Gare Saint-Lazare in Paris. He
tells Marie the hour of the train's arrival and he tells Jean at which minute it arrives. He
also tells them both that the train arrives between 0600 and 1000.
They consult the timetable and find the following services between those times:
0620, 0639, 0650; 0717, 0746; 0825, 0839; 0917, 0925, 0950.
Marie then says, “I don't know when Claude's train arrives, but I'm sure that neither does
Jean."
Jean replies, “I didn't know his train, but now I do."
Marie responds, “Now I do as well!"
When is Claude's train and how do you know?
Answers
Answer:
The train is 0839
Step-by-step explanation:
First off, 0620 and 0746 are not available options, as Jean would've immediately know, as they're the only one with non-repeated minutes.
Now, when Marie says "I'm sure neither does Jean", it means she didn't get 06 or 07, as those are the number that has 0620 and 0746, which then she cannot ensure that Jean doesn't know the train arrival.
We're left with 0825, 0839, 0917, 0925 and 0950
After that, Jean said he knows the train number. So, he couldnt've gotten 25, as it is repeated in the 5 options we pick. => we're left with 0839, 0917 and 0950.
And then, Marie responds now she does as well, which it cannot be 09, as it is repeated.
So, the train number is 0839.

Which equation matches the graph of the greatest integer function given below?
A. y= [x] + 3
B. y= [x] -3
C. y= [x] +2
D y= [x] -2
Answers
Answer:
D y= [x] -2
Step-by-step explanation:
The "floor" or "greatest integer" function graphs as a step function with a solid dot at the left end of each step. The point (0, 0) is one of those solid dots. When 2 is subtracted from the function value, the graph is shifted down 2 units so that it looks like the one given.
The given graph is of the equation ...
[tex]\boxed{y=\lfloor x\rfloor -2}[/tex]
_____
Additional comment
The ceiling function ...
[tex]y=\lceil x\rceil[/tex]
graphs as a step function with a solid dot at the right end of each step. There is a solid dot at (0, 0) for this function, as well.
Note that the function symbols have "hooks" above or below the argument to indicate ceiling or floor (respectively). The use of a square bracket [ ] for either of these functions would need to be accompanied by an explanation of the intended meaning. By itself, a square bracket has "hooks" both at the top and bottom, so does not represent either function unambiguously.

Use the parabola tool to graph the quadratic function f(x)=x2−12x+27.
Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.

Answer:
vertex = (6, -9)
point = (0, 27)

Step-by-step explanation:
[tex]f(x)=x^2-12x+27[/tex]
Vertex form: [tex]y=a(x-h)^2+k[/tex]
where (h, k) is the vertex
Rewrite function in vertex form:
[tex]\implies f(x)=(x-6)^2-36+27[/tex]
[tex]\implies f(x)=(x-6)^2-9[/tex]
Therefore, vertex = (6, -9)
As the coefficient of [tex]x^2[/tex] is positive, the parabola will open upwards (u shaped).

Use the data table on the left to complete the calculations. What is the elapsed time for Trial B? s What is the average speed for Trial B? m/s.
Answers
Speed is the ratio of distance and time
The elapsed time is 3 secondsThe average speed is 1.33 meters per secondHow to calculate the elapsed timeThe elapsed time is the difference between the final time and the initial time.
So, we have:
Time elapsed = 4.5 seconds - 1.5 seconds
Evaluate the difference
Time elapsed = 3 seconds
Hence, the elapsed time is 3 s
How to calculate the average speedThe average speed is the quotient of the distance and the elapsed time.
So, we have:
Average speed = 4 meters/ 3 seconds
Evaluate the quotient
Average speed = 1.33 meters per second
Hence, the average speed is 1.33 m/s

A 2-pound package is approximately $3.50 shipping fee.
A 4-pound package is approximately $4.50 shipping fee.
The question stated, "What is the approximate difference (this means we are most likely subtracting) in cost of shipping a 2-pound and a 4 pound package(the and means we are adding both 4-pound and 2-pound together) opposed to a single 6-pound package?"
As calculated above, we should add the 2-pound package and the 4-pound package together.
3.5 + 4.5 = 8
One single 6-pound package is $5, so we need to subtract the 8 with the 5.

Ahmed sells different types of cake in his shop.
The cost of each cake depends on its type and its size.
Every small cake costs $x and every large cake costs $(2x + 1).
The number of small cherry cakes that can be bought for $4 is the same as the number of large
cherry cakes that can be bought for $13.
Find the cost of a small cherry cake.
Answers
Answer:
$0.80
Step-by-step explanation:
Let y be the number of cakes that can be bought then...
xy=4
y(2x+1)=13
Distribute the y to each term in the parentheses...
y(2x)+y(1)=13
2xy+y=13
xy=4
Multiply the second equation by 2...
2xy+y=13
2xy=8
Solve the equation using elimination (subtract the two equations and eliminate 2xy)...
y=13-8=5
Now, plug 5 back in for y to solve for x...
xy=4
5x=4
Divide both sides by 5
x=$0.80
