According to given data, we can prove that Statement 1 is increasing function, Statement 2 is Decreasing Function, and Statement 3 is Constant Function.
1. The linear function that describes the relationship between the input value (number of days) and the output value (total number of texts sent) is y = 60x, where y is the total number of texts sent and x is the number of days. The graph of this function is increasing because as the number of days increases, the total number of texts sent also increases at a constant rate of 60 texts per day.
2. The linear function that describes the relationship between the input value (number of days) and the output value (total number of texts remaining for the month) is y = 500 - 60x, where y is the total number of texts remaining for the month and x is the number of days. The graph of this function is decreasing because as the number of days increases, the total number of texts remaining for the month decreases at a constant rate of 60 texts per day.
3. The linear function that describes the relationship between the input value (number of days) and the output value (total cost of texting each month) is y = 50, where y is the total cost of texting each month and x is the number of days. The graph of this function is constant because the cost of texting is the same regardless of the number of days.

A scatterplot that shows the number of hours studied on the x-axis and the number of errors on the y-axis would best support the teacher's observation.
What is error in math?Error in math is an incorrect answer to a mathematical equation or problem. It can be caused by a variety of factors, such as inaccurate calculations, misreading instructions, or not understanding the problem. Error in math can be frustrating and can lead to poor grades, but it can also be an opportunity for learning and growth. With the proper guidance and understanding, students can learn from their mistakes and become better mathematicians.
The scatterplot would likely show a negative correlation, with the number of errors decreasing as the number of hours studied increases. This indicates that as students study more, their performance on multiplication tests improves. It could also show an outlier or two, which could indicate that some students are able to learn multiplication facts more quickly than others.

What is the value of K if X 1 is the factor of 4x³ 3x² 4x K?
The value of k is -3, if x - 1 is a factor of 4x³ + 3x² − 4x + k.
A polynomial factor is a polynomial that divides another polynomial exactly, with no remainder.
For example, if we have a polynomial P(x) = 4x³ + 3x² − 4x + k, and we have a polynomial factor F(x) = x - 1, we can say that P(x) is divisible by F(x) with no remainder.
In general, a polynomial of degree n has n roots (or zeroes) and the factorization of polynomial can be expressed as a product of its roots and its corresponding multiplicity.
To find the value of k, set x = 1 in the equation 4x³ + 3x² − 4x + k and solve for k that will make the equation equal to zero..
So when x = 1, we have:
4x³ + 3x² − 4x + k = 0
4(1)³ + 3(1)² − 4(1) + k = 0
4 + 3 - 4 + k = 0
k = -3
Hence, if x - 1 is a factor of 4x³ + 3x² − 4x + k, then k is equal to -3.

Gong rented a truck for one day. There wa a bae fee of $19. 95, and there wa an additional charge of 71 cent for each mile driven. Hong had to pay $125. 74 when he returned the truck. For how many mile did he drive the truck?
Gong must have driven the truck for 149 miles as per the given problem.
Let’s discuss the problem in detail.
In addition to the base rate of $19.95, there was an extra fee of 71 cents for every mile driven. When Gong returned the truck, he was required to pay $125.74.
Now we have to calculate how far did he drive the truck before stopping.
First, let’s convert all dollars into cents.
Base fee = 1995 cents.
71 cents for each mile.
Total Gong gave 12574 cents.
Assume Gong drive for x miles.
Therefore, 12574 = 1995 + 71 * x
= 71x = 12574 - 1995
= 71x = 10579
= x = 10579/71 = 149 miles.
Hence, Gong drove the truck for 149 miles before stopping.

In the accompanying figure, angle 1 measures 28o and angle 2 measures 11o. What is the measure of angle 3
The measure of angle 3 in the given triangle is 141 degrees.
Angle 1 + Angle 2 + Angle 3 = 180°
So, Angle 3 = 180° - (Angle 1 + Angle 2)
Angle 3 = 180° - (28° + 11°)
Angle 3 = 141°
The sum of the three angles in a triangle is 180 degrees, so to calculate the measure of angle 3, we can subtract the measures of angles 1 and 2 from 180 degrees. In this case, angle 1 measures 28 degrees and angle 2 measures 11 degrees, so the measure of angle 3 is 180 degrees minus (28 degrees + 11 degrees), or 141 degrees.

What is the formula of image in straight line?
The formula of an image in a straight line is y = mx + c, where m is the slope of the line, x is the x-coordinate of the point and c is the y-intercept.
What is straight line?A straight line is a line whose points all lie in the same plane and all have the same distance from each other, making them all equidistant. The line does not curve or bend in any way, and can extend infinitely in either direction. Straight lines are the most basic form of geometric shape and are the foundation of all other shapes. The line is defined by two points, known as its endpoints, and any point that lies on the line is called a point on the line. Straight lines are important in mathematics, as they are used to describe relationships between points on a graph, and they can also be used to define equations and boundaries.
The y-intercept is the point at which the line crosses the y-axis. The slope of the line is determined by the ratio of the change in the y-coordinate to the change in the x-coordinate. To calculate the slope of a line, the formula m = (y2 - y1)/(x2 - x1) is often used, where (x1, y1) and (x2, y2) are two points on the line. Using the slope and the y-intercept, the formula can be used to plot the points of the image along a straight line.

What are the four types of triangles by angle measurement ?A triangle is said to be equilateral if each of its three sides is the same length. In the well-known Euclidean geometry, an equilateral triangle is also equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others.
A triangle having three acute angles is known as an acute triangle. A triangle having one obtuse angle and two acute angles is known as an obtuse triangle. No Euclidean triangle may contain more than one obtuse angle because in Euclidean geometry, a triangle's angles must add up to 180°.
A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Obtuse-angled triangles or obtuse triangles are triangles with any one of its angles being an obtuse angle or more than 90°. Only 180° is equivalent to the internal angles of an acute triangle.

How to use the Law of Cosines?Measure or determine the lengths of all three sides of the triangle (a, b, and c). Let's say a = 5, b = 6, and c = 7.
Substitute the side lengths into the formula above and solve for cos A. cos A = (6^2 + 7^2 - 5^2) / (267) = 0.6
Use the inverse cosine function to find the measure of angle A in degrees or radians. In this case, A = 60 degrees.
To find the length of side HI in triangle HIG, we can use the Pythagorean Theorem. The Pythagorean Theorem states that for any right triangle, the length of the hypotenuse (the side opposite the right angle) is equal to the square root of the sum of the squares of the other two sides.

Substitute the side lengths into the formula HI^2 = HG^2 + GI^2 and solve for HI. HI = √(8^2 + 6^2) = √(64+36) = √100 = 10
