What is the equation of the line that passes through the point (3,−5) and has a slope of 0?
Answer:
The answer is y + 5 = 0
Step-by-step explanation:
We know that, the equation of a line passing through point P(a, b) and slope m is given by
(y – b) = m(x – a) ...(1)
Here, The given point is P(3, -5) and slope is m = 0
from (1) we get
[(y – (-5)] = 0(x – 3)
y + 5 = 0 is the required equation of line.
Thus, The answer is y + 5 = 0

Countries with the highest populations in the world also have the highest population densities. True False.
Countries with the highest populations in the world also have the highest population densities is False.
What is a population?The number of people living in a country is known as population.
What is population density?The number of people living in a unit area is called population density. It is the ratio of the population of the country and the area of the country.
Countries with the highest populations in the world also have the highest population densities.
This statement is false because the population density depends on the area.
For example - China is having the first rank in population but its population density is 153 persons per kilometer square is much lesser than India which has a population density is 403 persons per kilometer square.

Huilan's age is two times Thomas's age. The sum of their ages is 87 What is Thomas's age?
Answer:
29
Step-by-step explanation:
We can make an equation from the word problem:
H +T =87
2T+T=87
3T=87
87÷3=29
T=29
This is our answer but we can substitute this into our equation:
H +T = 87
2T+T =87
2(29)+29 = 87
58+29=87
87=87
So 29 is ✅

Easy Question! Find the number that should be added to the expression to create a perfect square trinomial: x^2 − 8x
A) -64
B) -16
C) 16
D) 64
Answer: The answer is C
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

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.
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

What is the area of a picture of a silent that are 12 inches? Use The formula A=s^2, where is the length of one side
Answer:
144 in²
Step-by-step explanation:
Area of square: [tex]s^2[/tex]
Here s is 12 inches.
Using the formula:
area: [tex]s^2[/tex]
area: 12²
area: 12 * 12
→ 144 in²
The formula to find area of square is:
[tex] \tt \: area = {s}^{2} [/tex]
Where,
s is sideIn our case,
s = 12 inchesSo,
[tex] \sf \: area = {12}^{2} [/tex]

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:

Using Postulates and/or Theorems, determine whether ABC~AXY.
explain why the triangles are similar or why they are not.
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.

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)
see attached diagram for graph
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).
Point to plot:
f(0) = 27
Therefore, point = (0, 27)

A single 6-pound package is approximately $5 shipping fee.
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.
8 - 5 = 3

Let's start with how many perfect squares there are less than 1000. We have
0^2 = 0
1^2 = 1
2^2 = 4
3^2 = 9
...
30^2 = 900
31^2 = 961
32^2 = 1024
This means there are 0...31 so 32 perfect squares less than 1000.
Three times an odd integer... this is tricky. If you think about it, if n is divisible by three, then n must have a factor of 9 in it (why?), so [tex]\sqrt n[/tex] must have a factor of three! Boom, now we just have to count how many odd numbers from 0...31 are divisible by three. The first one is 1(3), the second is 3(3), the third is 5(3), the fourth is 7(3), and the fifth is 9(3). This means there are five such numbers.

In the diagram shown, altitude AC is drawn from a right angle to BD in such a way that BC: DC = 4:1 Find the length of DC algebraically. Show your work below.
Applying the altitude theorem and solving algebraically, the length of DC is: 6.
What is the Altitude Theorem?If an altitude of a right triangle divides an opposite side into a and b, based on the altitude theorem, the height (h) of the altitude = √(ab).
Solving algebraically:
Let DC = x
Therefore:
BC = 4x
Applying the altitude theorem, we would have:
12 = √(4x × x)
12 = √(4x²)
12 = 2x
12/2 = x
6 = x
x = 6
Therefore, DC = x = 6.

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?
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.
