What is the result of dilating a figure using a scale factor of 1?
Answers
When a figure is dilated using a scale factor of 1, the resulting figure is the same as the original figure.
This is because a scale factor of 1 means that the dimensions of the original figure are not changed in any way.
Mathematically, this is represented by the equation:
Original Length x Scale Factor = Resulting Length
For a scale factor of 1, the equation simplifies to:
Original Length x 1 = Resulting Length
Therefore, the resulting length is equal to the original length.
For example, if a line had a length of 5 units before dilating, the resulting length would be 5 units after dilating.
5 units x 1 = 5 units
This is because the scale factor of 1 does not change the length of the line in any way.

From the set {8, 19, 25}, use substitution to determine which value of x makes the inequality true
Answers
x = 19 and x = 25 make the inequality true.
What is inequality?
In mathematics, a relationship between two expressions or values that are not equal to each other is called 'inequality. ' So, a lack of balance results in inequality.
To use substitution to determine which value of x makes the inequality true, we can substitute each value from the set {8, 19, 25} into the inequality and see if it makes the inequality true or false.
For example, if the inequality is x < 10, we can substitute 8, 19 and 25 into the inequality to see which one makes it true:
8 < 10 is true
19 < 10 is false
25 < 10 is false
So, we can see that only 8 makes the inequality true. Therefore, x = 8 makes the inequality true.
If the inequality is x > 10, we can substitute 8, 19 and 25 into the inequality to see which one makes it true:
8 > 10 is false
19 > 10 is true
25 > 10 is true
Hence, x = 19 and x = 25 make the inequality true.

What is a function?
A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
A function or mapping is described as a collection of pairs of x and y that are ordered such that given different values of x, there will also be different values of y, or vice versa. For instance, the function x=y+2 yields a different x for every different value of y, while yielding the same x value for every single different value of y. We obtain two distinct x for two distinct ys, thus we can refer to this as a function at that point.
As, each element of X is associated with unique element of Y, so this is a function.

The price of a sweater bought by Rahul before the discount is Rs. 80.
Let us assume the price of the sweater before the discount to be x.
Given that,
The money saved by Rahul will be equal to the discount given for the sweater.
Therefore, we can say that Rs. 20 will be equal to 25% of the price of the sweater before the discount.
The equation we would obtain from the language above would be,
25% of x = 20
Solving this equation further, we can see that,
=> 25% of x = 20
=> 25* 1/100 * x = 20

Which explains why the commutative property of addition does not work for subtraction?
Answers
The commutative property of addition states that the order of the numbers being added does not affect the result. For example, the sum of 2 + 3 is the same as the sum of 3 + 2, which is 5.
The commutative property of addition does not work for subtraction because subtraction is not commutative. In subtraction, the order of the numbers being subtracted does affect the result. For example, the difference of 3 - 2 is 1, but the difference of 2 - 3 is -1.
The reason for this is that subtraction is the inverse operation of addition and the inverse operation of a commutative operation is not always commutative. In addition, subtraction is not commutative because when we subtract the smaller number from the larger number, we get a positive result but when we subtract the larger number from the smaller number we get a negative result.

Now,
Reflection in x = -3
Reflection rules over the y-axis.
(x, y) → (-x, y)
So,
x = -3
There are 3 units between -3 and -6.
So,
3 + 3 = 6 units will be added during reflection over y = -3
i.e
3 units on the left side of y = -3
3 units on the right side of y = -3

When g(x) is divided by x+1 the quotient is [tex]\frac{g(x)}{x+1}[/tex] = 2x-3+ [tex]\frac{k}{x+1}[/tex]
What is the value k?
Answers
The value of the constant k in the equation of the division of g(x) by (x + 1); [tex]\frac{g(x)}{x + 1} = 2\cdot x - 3 + \frac{k}{x + 1}[/tex] obtained by the long division of g(x) = 2·x² - x by (x + 1) is 3.
What is the method for the long division of a polynomial?The method or algorithm of finding the long division of a polynomial, p(x) known as the dividend, by a divisor, g(x) makes use of the equation;
p(x) = q(x) × g(x) + r(x)
Where;
q(x) = The quotient
r(x) = The remainder from the division;
The specified equation; [tex]\frac{g(x)}{x + 1} = 2\cdot x - 3+\frac{k}{x+1}[/tex], indicates that the remainder, r(x) = k.
The value of k in the specified equation, can be found by dividing the function g(x) = 2·x² - x, by (x + 1) as follows;
The expression obtained when g(x) is divided by (x + 1) using long division, is presented as follows;
[tex]{}[/tex] 2·x - 3
(x + 1) |2·x² - x
[tex]{}[/tex] 2·x² + 2·x
[tex]{}[/tex] -3·x
[tex]{}[/tex] [tex]{}[/tex] -3·x - 3
[tex]{}[/tex] [tex]{}[/tex] 3
The remainder obtained from the long division of 2·x² - x by (x + 1) is; 3
The result of the long division of 2·x² - x by (x + 1) is therefore;
[tex]\frac{g(x)}{x+1} =2\cdot x - 3 + \frac{3}{x + 1}[/tex]
Comparison of the equation; g(x)/(x + 1) = 2·x - 3 + k/(x + 1) and the equation; g(x)/(x + 1) = 2·x - 3 + 3/(x + 1), indicates that the value of k is 3

during which time interval did dylan maintain the fastest average speed
Answers
The time interval that saw Dylan maintain the fastest average speed was B. between hour 1 and hour 2.
Where did Dylan maintain the fastest speed ?Dylan maintained the fastest speed at the interval that saw him cover more distance in a shorter amount of time. You can find the speed at these intervals by using the speed formula of distance divided by time.
Speed between hour 0 and 1 :
= 25 miles / 1 hour
= 25 miles per hour
Speed between hour 1 and 2 :
= ( 75 - 25 ) / 1
= 50 miles per hour
Speed between hour 3 and 5 :
= ( 125 - 75 ) / 2
= 25 miles per hour
The fastest speed was therefore between hour 1 and 2.

What is an orthocenter of a triangle?
In geometry, an orthocenter is a point in a triangle that is the intersection of the three lines containing the altitudes of the triangle. An altitude of a triangle is a line segment from a vertex of the triangle to the line containing the opposite side, and is perpendicular to that side. The orthocenter of a triangle is the point where all the altitudes of a triangle meet.
To find the orthocenter of a triangle, the first step is to find the equation of the altitudes from each vertex. Then, we can find the point of intersection of these three lines.
Given the triangle ABC with vertices A (2,6), B (8,6), and C(6,2),
The equation of altitude from vertex A is (x-2) = -2(y-6)
The equation of altitude from vertex B is (x-8) = -2(y-6)
The equation of altitude from vertex C is (x-6) = 2(y-2)
By solving the system of these three equations, we can find the coordinates of the orthocenter.
Hence, The coordinates of the orthocenter of ABC are (6,4).
The correct option is C) (6,4)
