Its slope is m = 1 on the right side of the vertex, and m = - 1 on the left side of the vertex.
Absolute Value Function:
An absolute value function is a function that contains an algebraic expression within the absolute value sign. Remember that the absolute value of a number is its distance from 0 on the number line. To graph the absolute value function, select some values of x and find some ordered pairs.
In mathematics, the absolute value or modulus of the real number x, represented as.
|x| is the non-negative value of x, regardless of sign.
x is positive and |xI =-x}. For example, the absolute value of 3 is 3, and the absolute value of -3 is also 3. The absolute value of a number can be thought of as the distance from zero.
Generalizations of the absolute value of real numbers are made in a variety of mathematical contexts. For example, absolute value is also defined for complex numbers, quaternions, ordinal rings, fields, and vector spaces. Absolute value is closely related to the concepts of magnitude, distance, and norm in various mathematical and physical contexts.

You are planning to sell ice cream cones for a school sporting event . You plan to sell 300 ice cream cones. Before selling the ice cream, you give a survey to determine what flavors to sell. The results are below.
• 10% - Mint
• 25% - Strawberry
• 15% - Chocolate chip
• 50% - Vanilla
Based on the survey results, how much of each flavor will you sell at the sporting event
Answer: Based on the survey results, we can calculate the number of ice cream cones to sell for each flavor by multiplying the percentage of the flavor by the total number of ice cream cones to be sold.
Mint: 10% of 300 ice cream cones = 0.1 * 300 = 30 ice cream cones
Strawberry: 25% of 300 ice cream cones = 0.25 * 300 = 75 ice cream cones
Chocolate chip: 15% of 300 ice cream cones = 0.15 * 300 = 45 ice cream cones
Vanilla: 50% of 300 ice cream cones = 0.5 * 300 = 150 ice cream cones
So, based on the survey results, you should sell 30 ice cream cones of Mint flavor, 75 ice cream cones of Strawberry flavor, 45 ice cream cones of Chocolate chip flavor, and 150 ice cream cones of Vanilla flavor.
It's worth mentioning that the sum of the percentages provided, 10+25+15+50 = 100%. Which means that it is a proper survey and the total number of ice cream cones you expect to sell is equal to the survey results.
Step-by-step explanation:
Based on the survey results flavors sold at the sporting event are, 30 mint ice creams, 75 Strawberry icecreams, 45 Chocolate chip icecreams, and 150 Vanilla icecreams.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
The number of different types of ice creams can be obtained as follows,
10% - Mint.
= (10/100)×300.
= 30.
25% - Strawberry.
= (25/100)×300.
= 75.
15% - Chocolate chip.
= (15/100)×300.
= 45.
50% - Vanilla.
= (50/100)×300.
= 150.

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Interior angles are,
⇒ ∠ C = 83°
⇒ ∠ B = 6x + 7
An exterior angle is,
⇒ ∠ A = 15x
Now, We know that;
The sum of two interior angles in a triangle is equal to the exterior angle in a triangle.
⇒ 83° + 6x + 7 = 15x
⇒ 90 = 15x - 6x

The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by __
The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by the function P(x) = 31 + 2.6x.
What is the percentage function?
To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100. Percentage formula = (Value/Total value) × 100. Example: 2/5 × 100 = 0.4 × 100 = 40 per cent.
The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by the function:
P(x) = 31 + 2.6x
Where P(x) is the percentage of adults who viewed college education as essential for success x years after the first year, and x is the number of years after the first year.
The function shows that the percentage increase by 2.6 every year for x years after the first year, and the initial percentage is 31%.
This function is representing a linear trend since the coefficient of x is constant.

A family drives 4 1/4 miles in 1/10 of an
hour. How many miles will they drive
in 3/4 hour?
Therefore because of this, the answer to the speed problem is that a family can travel 31.875 miles in 3/4 of an hour.
Describe speed.Speed is a tempo that is determined by the distance an entity travels in a predetermined period of time. Numerous methods exist for measuring speed, including miles per hour, laps per minute, and meters per second. The measurements of speed, distance, and time are related. The relationship can be expressed in three different ways:
D = RT, R = DT, & T = DR.
Here,
We are given that
Distance drives by a family=4[tex]\frac{1}{4}[/tex] miles
Time = 1/10
We have to find the rate of speed in miles per hour.
The speed formula will be used to get the velocity in miles per hour.
Distance traveled in a given amount of time equals speed.
=> Speed = 17/4 * 10
=> Speed = 42.5
So, using the calculation, we arrive at 42.5 miles per hour.
The miles traveled in 3/4 miles are therefore:
Distance is calculated as speed times time,
therefore 42.5 * 3/4 would equal 31.875 miles in distance.
Because of this, the answer to the speed problem is that a family can travel 31.875 miles in 3/4 of an hour.

How many times larger is the diameter of Uranus? Write your answer in standard notation, rounding to the nearest tenth.
The number of times the diameter of Uranus is larger than the diameter of Mars is 7.5 times
How to determine the number of times larger is the diameter of UranusFrom the question, we have the following parameters that can be used in our computation:
The diameters of Uranus and Mars
These diameters are given as
Diameter of Uranus: 5.11×10^4 kilometers
Diameter of Mars: 6.79×10^3 kilometers
Express the diameters properly
So, we have the following representation
Diameter of Uranus: 5.11 × 10⁴ kilometers
Diameter of Mars: 6.79 × 10³ kilometers
This means that
Number of times larger = Diameter of Uranus/Diameter of Mars
Substitute the known values in the above equation, so, we have the following representation
Number of times larger = 5.11 × 10⁴ kilometers/6.79 × 10³ kilometers
Evaluate the quotient
So, we have the following representation
Number of times larger = 7.5

Write an equation for the value y (in dollars) of the stock after x weeks.
b. If this trend would continue, what would be the value of the stock after 20 weeks?
The Equation for the value y is a. y = 21 + 0.25x (where x represents the number of weeks)
b. The value of the stock after 20 weeks would be 21 + (0.25 * 20) = $26.
This equation represents the linear relationship between the value of the stock (y) and the number of weeks (x). The value of the stock is initially $21, and it increases by $0.25 every week. This is represented by the coefficient of x (0.25) in the equation. By plugging in x=20 into the equation, we can find that after 20 weeks, the value of the stock would be $26.

PLEASE THIS IS URGENT
During the winter, the grill was marked at $85. In June, the price was changed to $110. 50. So, 23.08% is the change in percentage.
What is percentage?When the denominator is 100, percentages are really just fractions. We place the percent sign (%) next to the number to indicate that the number is a percentage.
Comparing two amounts while re basing the second amount to 100 is the simplest way to use percentages. The word percentage comes from the Latin term per centum, which means "by the hundred." In the 16th century, the Latin term made its way into English. It was later abbreviated to %.
Given that,
the grill was marked at $85
the price was changed to $110. 50.
Now, percentage change:
= [{(110. 50 - 85)/110.50} × 100]
