The slope is the measure of the steepness and direction of a line. You can predict whether lines in a coordinate plane are parallel, perpendicular, or none by finding the slope of the lines.
There are two distinct points on any line that can be used to calculate its slope. Between two distinct points on a line, the slope formula calculates the ratio of vertical and horizontal changes. In mathematics, the slope is calculated as the ratio of the rise to the run, or as the rise divided by the run. The slope is a measure of how steep a line is in a coordinate plane.

Expressions that indicate the total number of bottles purchased
The formula 3p + 11 can be used to express how many bottles André purchased.
The formula that can be used to express how many bottles Jillian purchased is 5p + 3
Where:
P is the number of bottles in the purchased packs.

How do you draw a dilation with a scale factor of 1 2?
To draw a dilation with a scale factor 1/2 , multiple every coordinates of pre-image with 1/2 and join the obtained points
A dilation is a transformation that alters the size of an image.
There is a centre and a scale factor in all dilations. The centre serves as the dilation's reference point (like the vanishing point in a perspective drawing)
The scale factor indicates how much the figure expands or contracts. A scale factor is usually denoted by the letter "k," and it is always greater than zero.
To draw a dilation with a scale factor of 1/2, follow these steps:
Step 1: Determine the scale factor and the dilation centre.
Step 2: Identify an image vertex. Draw a line through one of the image's vertices from the center of dilation.
Step 3: Find the horizontal distance and the vertical distance between the center of dilation and the vertex.
To find the horizontal and vertical distances from the centre of dilation to a new vertex, multiply the distances by the scale factor 1/2.
Step 4: Determine the new horizontal and vertical distances from the centre of dilation. Make a point plot.
Step 5: Join the new vertices together to create the dilated image.

Which transformations could have taken place to map △ABC to △A"B"C".
The following answer has been given keeping in mind the above question.
The transformations that should have been taken place are a rotation and a dilation.
What is a rotation?
Rotation is when we rotate a figure to a certain degree. In a rotation, points and figures are turned on a coordinate plane. Majorly, rotations are about to the origin. Rotating a point about the origin can be, imagine a line connecting the origin to a point, and then rotate the line clockwise by the correct angle of rotation.
What is a dilation?
Dilation is a process of transformation in which something can be made larger or smaller. In a dilation, a point, a set of points can be expanded or contracted in relation to the origin. In expansion, the points in a figure move far away from the origin, and the side lengths of the figure increase. In a contraction, the points of the figure move closer to the origin, and the side lengths in the figure tend to reduce.

a) how many license plates are possible if each plate must have three letters followed by three numbers?
The permutation combination of license plate is 35152000.
Numbers can be 10 digits (0, 1, 2, …, 9) and 26 letters (A, B, C, ..., Z).
Repetition is allowed, leaving 26 next choices for each letter used and 10 next choices for each digit used.
Therefore, according to the multiplication principle, the total number of different letter permutations.
26× 26 × 26 = 17576
and the total number of digit permutation: 10 × 10 × 10 = 1000
now, they can be in any order:
⁶C₃ = 6!/(6−3)!3!

find the measure of the interior angles x, (x-24), and 68
Answer:
68, 68, 44
x = 68
x - 24 = 44
Step-by-step explanation:
If you have a shape with three interior angles, it is a triangle. The three angles in a triangle add up to 180. Use this idea to write and solve an equation.
x + (x - 24) + 68 = 180
Combine like terms.
2x + 44 = 180
Subtract 44.
2x = 136
Divide by 2.
x = 68
So we can find x - 24
68 - 24 is 44.
The three angles are 68 (given), 68 (because x = 68), and 44 (because x-24)
The angles are 68, 68, and 44
S varies directly as t. if s is 20 when t is 4 then t is ____ when s is 30
Answer:
Therefore, when s is equal to 30, t is equal to 30 / 5 = <<30/5=6>>6.
Step-by-step explanation:
Direct variation means that the ratio between two variables is always constant. In this case, the constant ratio between s and t is equal to 20/4 = 5. This means that when t is equal to 4, s is equal to 20 and the ratio between the two is 5. If s is equal to 30, we can find the corresponding value of t by setting up the following equation:
s / t = 5
We can then solve for t by multiplying both sides of the equation by t to get:
s = 5 * t
If we substitute 30 for s, we get:
30 = 5 * t
We can solve for t by dividing both sides of the equation by 5:
t = 30 / 5
Therefore, when s is equal to 30, t is equal to 30 / 5 = <<30/5=6>>6.

How do you find the maximum and minimum values of a set?
To find maximum value and minimum value in a set we have to use ven diagram from set theory.
Here we are taking an example?
Let A and B be 2 sets having elements 4 and 7 respectively. Then write the maximum number of elements that A∪B can have.
Let us assume that:
Number of elements of A is equal to n (A).
Number of elements of B is equal to n (B).
Number of elements of A∩B is equal to n (A∩B).
Now, the formula for the elements of A U B is as follows:
n(A∪B)=n(A)+n(B)−n(A∩B)
It is given in the question that, number of elements in set A is equal to 4 and number of elements in set B is equal to 7. So, we can write:
n (A) = 4, n (B) = 7
n (A∩B): the number of elements which are common in both the sets A and B.
We have to find the maximum number of elements which are in n(A∪B). So, the maximum of n(A∪B) is when n(A∩B) is minimum and the minimum of n(A∩B) is 0.
n(A∪B)=n(A)+n(B)−n(A∩B)⇒n(A∪B)=4+7−0⇒n(A∪B)=11
Hence, the maximum number of elements in A∪B is 11.
Note: You might be wondering, why for maximizing the n (A∪B) we have to minimize n (A∩B) and why the minimum value of n (A∩B) is 0.
In the formula for n (A∪B),
n(A∪B)=n(A)+n(B)−n(A∩B)
L.H.S will be maximized when in the R.H.S; the term after minus sign will be minimized. Hence, n (A∩B) must be minimized.
The minimum possible value of n (A∩B) is 0 means that the elements in the set A and B are such that there is not a single element is common in both the sets. And it could be possible that we have two sets and the sets have no element in common.
When no elements is common in both the sets, the n (A∩B) is ∅.
The set which has no element in it is called a null set or an empty set.
By this we can find maximum and minimum value in a set.

Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4. 1,056 66 16. 5.
The Variable x varies inversely with y, and x = 132 when y = 4 then the value of x is 16.5 when y = 32.
So, the correct option is option(D).
Inverse variation can be expressed by the formula, xy=k or y=kx
That is, if there is a non-zero constant k such that xy = k or y = kx (x≠0,y≠0), then y varies inversely with x.
We have given that,
x varies inversely with y and we need to find x when y = 4 when x = 132
X varies inversely with y there exist a constant of proportionality say k such that :
=> (x)(y) = k ----(1)
Put the value of x and y in equation (1) to find the value of k
=> (132)(4) = k
Therefore, k = 528 , We get
=> (x)(y) = 528
Now, we find x when y = 32, so plug the value of y in equation (1)
=> (x)(32) = 528
=> x = 528/32
=> x = 16.5
Hence, the value of x is 16.5 when y = 32 .

Given line is y = 3x + 1
We need to find equation of line parallel to this line
Let us consider the equation of line as y = mx + c
We know that two lines are parallel if they have same slope i.e. m1 = m2
Here m1 = 3
So slope of required line m2 = 3
We need to find the value of c
Let us take a point (x1, y1) common to both lines
We know that (1/2, 0) is common to both lines
So x1 = 1/2, y1 = 0
Substituting these values in y = mx + c
0 = 3(1/2) + c
