Step-by-step explanation:
C.
The solution to this is x ≤ 4.
So then we look at the graphs and choose the correct one.
When the sign is ≤ it's like an arrow whatever way it's pointing it goes that way. In this case it'd go the other way even though the sign is ≤, because the solution is stating 4 is greater then or equal to so it can't be less than 4. And the only option of +4 and higher is C.
Divide 26hours and 6minutes by 6.
Answer:
26 hours + 6 minutes can also be said as 1560 min + 6 minutes
1560+6/6 = 1566/6 = 261
That is = 4 hours and 21 minutes

Answer:
AC =5
BC = 12
AB = 13
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
(n-1)^2 + (2n)^2 = (n+7)^2
FOILing
n^2-2n+1 + 4n^2 = n^2+14n+49
Combine like terms
5n^2-2n+1 = n^2+14n+49
Bring everything to the left
5n^2-2n+1 -n^2-14n-49 = n^2+14n+49-n^2-14n-49
4n^2 -16n -48 = 0
Divide by 4
n^2 -4n -12 = 0
Factor
( n-6)(n+2) =0
Using the zero product property
n-6 =0 n+2 =0
n=6 n=-2
Since the length cannot be negative
n=6
AC = n-1 = 6-1 =5
BC = 2n = 2*6 = 12
AB = n+7 = 6+7 = 13
Given :
Hypotenuse of right angle triangle = n + 7
Base = n - 1
Altitude = 2n
Using Pythagoras theorem :
→ ( n + 7 )² = (n - 1)² + (2n)²
→ n² + 14n + 49 = n² - 2n + 1 + 4n²
→ n² + 14n + 49 = 5n² - 2n + 1 = 0
→ n² + 14n + 49 - 5n² + 2n - 1 = 0
→ -4n² + 16n + 48 = 0
→ -4(n² - 4n - 12) = 0
→ n² - 6n + 2n - 12 = 0
→ n(n - 6) + 2(n - 6) = 0
→ (n - 6)(n + 2) = 0
As n ≠ Negative
So, n ≠ -2
So, n = 6
Hypotenuse = n + 7 = 6 + 7 = 13
Base = n - 1 = 6 - 1 = 5
Altitude = 2n = 2 × 6 = 12
So,
AB = 13
AC = 5
BC = 12

Explain how you find the scale factor using 2-3 sentences or showing each step. Explain using the ratio of the image length to the pre-image length.
Answer/Step-by-step explanation:
The scale factor = the ratio of the corresponding sides of the image and the preimage.
That is, A'B'/AB = B'C'/BC
The preimage is the smaller figure, given as ABCD.
AB = 3 - 1 = 2 units
BC = 4 - 1 = 3 units
The image is the larger figure, given as A'B'C'D'.
A'B' = 9 - 5 = 4 units
B'C' = 7 - 1 = 6 units
Scale factor = [tex] \frac{4}{2} = \frac{6}{3} = 2 [/tex]

A number is decreased by seven. Then, the new number is multiplied by 3 to get an answer of -9. What is the original number? A. -4 B. -30 C. 4 D. 30
Answer:
The answer is c
Step-by-step explanation:
You have to do everything backwards,
-9 divide it by 3 to get -3, then add seven to that answer
Answer:
C
Step-by-step explanation:
You can work backward to find out the answer!
Start with -9. Instead of multiplying by 3, you can divide.
-9/3 = -3
Now, instead of decreasing -3 by 7, increase by 7.
-3+7 = 4
You get 4, which is C!
Hope this helps!
Equivalent to 1/2 (36x -14) +(2x-9)?
Answer:
20x - 16
Step-by-step explanation:
We can first do 1/2 (36x - 14), getting 18x - 7.
Then our expression becomes 18x - 7 + 2x - 9.
We can combine like terms, getting 20x - 16.

Please mark me as a brainlist...... Please follow me.......What is the dependent and independent variable?and
What is the (x) and (y) axis?
Answer:
and independent variable It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. and a Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
The term "elevation" is often used to describe the height of a place (such as a city, a mountain, or a valley) compared to sea level. For example, the city of Houston, Texas has an elevation of 105 feet. The surface of the sea has an elevation of 0 feet. Some places are below sea level, so their elevations are negative values. Two towns have different elevations, but when the elevations are used as inputs of , they both produce an output of 25. Why do they produce the same output?
Answer:
obviously they will produce same output because the elevation of object and image will be same
what is the doors width in simplest form
Answer:
x + 6
Step-by-step explanation:
From the question given above, the following data were obtained:
Length of rectangle = 3x + 6
Width of rectangle = 4x – 1
Width of door =..?
A careful observation of the diagram shows that the door is located along the length of rectangular room.
In a rectangle, two sides are equal. Therefore,
x + door + x = 3x + 6
Making door subject of the above formula, we have:
x + door + x = 3x + 6
door + x + x = 3x + 6
door + 2x = 3x + 6
Subtract 2x from both side
door + 2x – 2x = 3x + 6 – 2x
door = 3x – 2x + 6
door = x + 6
Therefore, the width of the door is x + 6

===============================================
Let a,b,c,d be scalars.
In general if v and w are two vectors such that
v = <a, b>
w = <c,d>
then the difference of the two vectors is
v - w = <a-c, b-d>
so we subtract the coordinates

v = <9, -1>
w = <-1, -6>
v - w = <9 - (-1), -1-(-6)>
v - w = <9+1, -1+6>
v - w = < 10, 5 >
While traveling to Europe, Phelan exchanged 250 US dollars for euros. He spent 150 euros on his trip. After returning to the United States he converts his money back to US dollars. How much of the original 250 US dollars does Phelan now have? Round to the nearest cent. 1 European euro = 1.3687 US dollars
Answer: Phelan now have 44.69 US dollars. of the original 250 US dollars.
Step-by-step explanation:
Given, Phelan spent 150 euros on his trip.
1 European euro = 1.3687 US dollars
So, 150 euros = 150 × 1.3687 US dollars
= 205.305 US dollars
≈ 205.31 US dollars [ Rounded to the nearest cent. ]
Initially he had 250 US dollars, now he has left (250-205.31)US dollars that is
44.69 US dollars.
Hence, Phelan now have 44.69 US dollars. of the original 250 US dollars.
Phelan now have 44.69 US dollars. of the original 250 US dollars.

7) If AB = 3x - 8 and BC = x + 12, find the value of x.
Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question.
In a square ABCD, if AB = (3x-8) and BC = (x+12), find the value of x. Also, find the length of each side of the square.
Note that all sides of a square are equal. Hence AB = BC for the square ABCD.
Given AB = (3x-8) and BC = (x+12), then AB = BC
3x-8 = x+12
collect like terms;
3x-x = 12+8
2x = 20
x = 20/2
x = 10
Substitute x = 10 into any of the side. Using side AB
AB = 3x-8
AB = 3(10)-8
AB = 30-8
AB = 22
BC = x+12
BC = 10+12
BC = 22
Hence x = 10 and the length of each side is 22

using complete sentences discuss a different kinds of real numbers in your answer. Give an example of each type and discuss which set each type.
Answer:
Real numbers are mainly classified into rational and irrational numbers. Rational numbers include all integers and fractions. All negative integers and whole numbers make up the set of integers. Whole numbers comprise of all natural numbers and zero.
There are 4 types of real numbers.
Rational Numbers
Irrational Number
Natural Numbers
Whole Numbers
What are the real numbers?Real numbers include rational numbers like positive and negative integers, fractions, and irrational numbers.
The set of real numbers, which is denoted by R, is the union of the set of rational numbers (Q) and the set of irrational numbers.
Rational Numbers; Any number specified in the form of a p/q or ratio fraction is called a rational number. The numerator is defined as p, and the denominator is represented as q, where q is not equal to zero. A rational number may be an integer, whole, and natural number.
For example: 0.67, 17, 214, etc.
Irrational Number; Irrational numbers are defined as the real number that cannot be represented as a simple fraction. In other words, it cannot be represented as a ratio, such as p/q, where p and q are integers, q≠0. It is the opposite of rational numbers.
For example; √5, √11, √21, etc.
Natural Numbers; An integer greater than 0 is a natural number. Natural numbers start at 1 and move to infinity.
For example; 1, 2, 3, 4, 5.
Whole Numbers; The whole number is the number system that contains all positive integers from 0 to infinity. The whole number is an integer of 0 or greater numbers.
For example: 1, 2, 3, 4, 5…..
