a. In interval notation, Increasing intervals: (12pm, 1pm) U (1pm, 2pm) U (2pm, 3pm). Decreasing intervals: (8am, 9am) U (11am, 12pm). Constant intervals: (9am, 10am) U (10am, 11am)
b. The increase in cost between 12 noon and 3 pm is $2.
c. Yellow Cab has a lower price per 1km than Swift ride at (8am, 9am) (9am, 10am) (2pm 3pm)
How do you express a data set in interval notations?Interval notation is used to represent continuous intervals of numbers or values, like ranges on a number line.
The graph shows that from 8-9am, and 11-12pm, the cost from Swift Ride decreases.
We can represent it as (8am, 9am) U (11am, 12pm).
It increases at these times (12pm, 1pm) U (1pm, 2pm) U (2pm, 3pm).
And stays constant at : (9am, 10am) U (10am, 11am)
Cost increase from 12 to 3pm,We simply deduct the 12pm's cost from 3pm's cost.
So, we have
Cost increase = $3.5 - $1.5
Evaluate the difference
Cost increase = $2
Hence, the cost increase is $2
The time interval where the cost is lowerWhen you plot the points provided for Yellow cab, you'll notice that Yellow Cab has a lower price per 1km than Swift ride at (8am, 9am) (9am, 10am) (2pm 3pm)

Linear equation: -1 2 (6x + 10) = 13 Step 1: –3x – 5 = 13 Step 2: –3x = 18 Step 3: x = –6 Which sequence describes the inverse operations used for steps 2 and 3 to solve the linear equation? the addition property of equality and then the division property of equality the addition property of equality and then the multiplication property of equality the subtraction property of equality and then the division property of equality the subtraction property of equality and then the multiplication property of equality
Answer:
(A) the addition property of equality and then the division property of equality
Step-by-step explanation:
To get from Step 1 to Step 2, we have added 5 to both sides of the equation:
-3x -5 +5 = 13 +5
-3x = 18
To get from Step 2 to Step 3, we have divided both sides of the equation by -3:
-3x/-3 = 18/-3
x = -6
These operations can be described as ...
the addition property of equality and then the division property of equality

However, since addition and subtraction are the same thing, but with opposite numbers, and since multiplication and division are the same thing, but with reciprocal numbers, any of the answer choices is arguably correct.

The value of x will be 18.67 for the given data of the triangle.
We have,
Thale's theorem:
When a line parallel to one side of a triangle intersects the other two sides in distinct points, the other two sides are divided in the same ratio.
Given that the sides of the triangle are divided into two parts,
For the left part the parts will be x and x + 7 for the right side the parts will be 16 and 22.
The ratio will be the same according to Thale's theorem. The value of x will be calculated as:-
x / ( x + 7 ) = 16 / 22
22x = 16x + 112
6x = 112
x = 112 / 6
x = 18.67
Therefore, the value of x will be 18.67.

Find the values of x and y. Find value of x.
The sum of two numbers is 96 the larger number is nine less than four times the smaller number find both numbers
Answer:
21 and 96
Step-by-step explanation:
Let x and y be the two numbers such that x>y.
As the sum of both the numbers is 96.
x+y=96...(i)
As the larger number is nine less than four times the smaller number,
So, x=4y-9
From equation (i),
4y-9+y=96
5y=96+9=105
So, y=105/5=21
By using equation (i),
x=96-y=96-21=75
Hence, both the numbers are 21 and 96.
Consider the function \(y=\sqrt{5x-5}+1\)
Which inequality is used to find the domain?
The inequality is used to find the domain of the given function is
5x-5 ≥ 0
What is a function?A function is a relation from a set of inputs to a set of possible outputs, where each input is related to exactly one output.
Given is function y = √(5x-5)+1, we have to find which inequality can be used to find the domain.
Since, the function is a square root function.
We know that,
The square root function is defined only for the positive values, including 0. i.e. the expression inside the square root must be greater than or equal to 0.
The expression inside the square root is (5x-5) so that must be greater than or equal to 0 which can be written as :
5x-5 ≥ 0
Hence, the inequality is used to find the domain of the given function is 5x-5 ≥ 0

“To love your country is to desire to see it become the best version of itself, to point out its failures, to recognize how we each have been complicit in allowing its worst to persist, to work together to create a community in which every resident has all that they need — love, food, shelter, health, peace, prosperity — and are truly treated as equals in every regard.”

The coldest temperature ever recorded in Mathville was - 16 deg * F This happened on January 30th, 1978. The normal low for that day is 19 deg * F How much colder was the record temperature than the normal ow temperature?
It was recorded 35°F colder temperature than the normal ow temperature that year in January 30th, 1978.
Explain the term temperature change?Diabatic temperature change is the term used to describe a temperature shift brought on by a heat exchange between two bodies. The term "adiabatic temperature change" refers to another highly significant method of altering the temperature of air. Air undergoes adiabatic temperature change without the addition or subtraction of energy.For the stated data-
Coldest temperature : -16°F
Normal low: 19°F
Thus, the difference in the temperature-
Difference = Normal low - Coldest temperature
Difference = 19°F - (-16°F)
Difference = 35°F
Thus, it was recorded 35°F colder temperature than the normal ow temperature that year in January 30th, 1978.

In the diagram of △△ADC below, EB∥∥DC, AE=2, AB=10, and BC=45. What is the length of AD?
Answer:
11 units
Explanation:
Given that lines EB and DC are parallel, we use the proportional division theorem:
\(\frac{AE}{ED}=\frac{AB}{BC}\)Substitute the given values:
\(\begin{gathered} \frac{2}{ED}=\frac{10}{45} \\ \text{Cross multiply} \\ ED\times10=2\times45 \\ \text{Divide both sides by 10} \\ \frac{ED\times10}{10}=\frac{2\times45}{10} \\ ED=9 \end{gathered}\)Next, find the length of AD:
\(\begin{gathered} AD=AE+ED \\ =2+9 \\ =11\text{ units} \end{gathered}\)The length of AD is 11 units.
Alternate Method
\(ED=AD-2\)So, we have that:
\(\frac{AE}{ED}=\frac{AB}{BC}\implies\frac{AE}{AD-2}=\frac{AB}{BC}\)Substitute the given values:

What the meaning of statement this?
If p(x) ⊆ p(y), then it means that every element of the power set of x is also an element of the power set of y. This implies that set x is a subset of set y, written as x ⊆ y.
Here,
Let A be the set x and B be the set y. Then the power sets of A and B are p(A) and p(B) respectively.
Suppose p(A) ⊆ p(B). This means that for every element a in p(A), a is also an element of p(B).
Now consider any element a in A. Since a is an element of A, it is also an element of its power set p(A). Thus, if p(A) ⊆ p(B), a must also be an element of p(B). This means that a is an element of B.
Therefore, we have established that every element of A is an element of B. That is, A ⊆ B.
Thus, if p(x) ⊆ p(y), then x ⊆ y.

The solutions to the absolute value equations are:
1. b. x = 1, -19. 2. a. no solution. 3. c. x = 5, -9.
How to Solve Absolute Value Equations?1. |3x+9| = 30
To solve this equation, we isolate the absolute value expression by considering two cases: 3x+9 = 30 and -(3x+9) = 30. Solving both equations, we find x = 7 and x = -19, respectively. Thus, the answer is b. x = 1, -19.
2. |2x+11| = -13
An absolute value cannot be negative, so there is no solution to this equation. The answer is a. no solution.
3. |x + 2| + 4 = 11
To solve this equation, we isolate the absolute value expression by subtracting 4 from both sides, resulting in |x + 2| = 7. Considering two cases: x + 2 = 7 and -(x + 2) = 7, we solve for x and find x = 5 and x = -9, respectively. Thus, the answer is c. x = 5, -9.

Answer:

Step-by-step explanation:
I like to use the FOIL method! I've attached a quick picture of how it works below, but basically you multiply the first terms. Next, multiply the outside/outer terms. Then, multiply the inside/inner terms. Lastly, you multiply the last terms.
In this question, the binomial is (x + 2)².
You can expand this to be (x + 2)(x + 2).
When you expand it using the FOIL method, you get x times x, which is x².
Next, the outside/outer terms are x and 2, which is 2x.
Then, you multiply the inside/inner terms 2 and x, which is 2x.
Last, you multiply the last terms, which are 2 and 2, which is 4.
When you put them together, it looks like this:
x² + 2x + 2x + 4.
You can simplify this to x² + 4x + 4.
So your answer is 4.
