Answer:

Parallel lines and their transversal all have equal slopes.

Step-by-step explanation:

I say this is wrong because the slope of parallel lines is equal but the transversal has a different slope.

a. If A says "The two of us are both knights" and B says "A is a knave," then we know that one of them must be lying, and thus that one of them is a knave. However, we cannot determine from this information alone which of them is the knave and which is the knight.

b. If A says "At least one of us is a knave" and B says nothing, then we know that one of them is a knave, but we cannot determine from this information alone which of them is the knave and which is the knight.

In the first scenario, person A claims that both he and person B are knights, which is a true statement if A is a knight. However, person B says that A is a knave, which means that A is a liar. These statements contradict each other, so we know that one of them is not telling the truth and is therefore a knave. But we cannot determine which one of them is the knave, because we don't have enough information.

In the second scenario, person A says that at least one of them is a knave, and person B remains silent. This means that A could be telling the truth, or could be lying. If A is a knight, then he is telling the truth and at least one of them, B, is a knave. But if A is a knave, then he could be lying and both of them could be knights. So we don't have enough information to know who is a knave and who is a knight.

The given inequality can be correctly shown in the graph containing all the numbers greater than or equal to 3. The correct option is (D).

A number line is a graphical representation of numbers on a line.

The number line has one convention that the positive numbers are always on the right side of the origin and the negative numbers are on the left side.

The inequality is given as below,

[tex]\frac{7x-3}{9} \geq 8 - 2x[/tex]

It can be solved as follows,

[tex]\frac{7x-3}{9} \geq 8 - 2x[/tex]

Multiply both sides by 9 to get,

⇒ 7x - 3 ≥ 9(8 - 2x)

⇒ 25x ≥ 75

⇒ x ≥ 3

It implies that the solution is the set of numbers greater than or equal to 3.

Hence, the solution of inequality is obtained as number line satisfying x ≥ 3.

Step-by-step explanation:

the value of the Perpendicular distance of F from Chord AB is 10.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

Given a circle, Where F makes a right angle triangle with the chord CD and also with Chord AB.

We know that,

Equal chords of a circle are equidistant from the center of a circle.

Here,

Chords AB and CD are equal to 18.

So, Chords AB and CD are equidistant from F(center of the circle).

Thus, x = 10

therefore, the value of the Perpendicular distance of F from Chord AB is 10.

It can be concluded that the given coordinates of A(2,3), B(4,6), C(7,4) and D(a,b) can be used to determine the length of the sides as well as the angles of the quadrilateral ABCD.

A quadrilateral is a four-sided polygon with four angles. It is a two-dimensional shape that is bounded by four line segments, each of which is called a side. The sum of the angles of a quadrilateral is 360 degrees. Types of quadrilaterals include rectangles, squares, trapezoids, parallelograms, and kites.

First of all, ABCD is a quadrilateral, which means it has four sides and four vertices. A, B, C and D are the vertices of this quadrilateral. It can be seen that A(2,3), B(4,6), C(7,4) and D(a,b) given in the question are coordinates of the vertices. Therefore, from these coordinates, we can conclude that A, B, C and D are the vertices of the quadrilateral ABCD.

Moreover, these coordinates can also be used to determine the length of the sides of the quadrilateral. The distance between A and B can be calculated by using the Pythagorean theorem. Similarly, the lengths of other sides can also be calculated by using the same theorem. Furthermore, the coordinates will also help us to calculate the angles formed by the sides of the quadrilateral ABCD.

Therefore, it can be concluded that the given coordinates of A(2,3), B(4,6), C(7,4) and D(a,b) can be used to determine the length of the sides as well as the angles of the quadrilateral ABCD.

The graph of the equation 30x+6y=180 will be a line in the xy-plane.

An equation is a mathematical statement that expresses the equality of two expressions. It is composed of one or more terms and an equal sign, and can contain constants, variables, and operators. Equations are used to represent relationships between different values, quantities, and objects, and to solve for unknowns. Equations are a fundamental tool of mathematics and can be used to describe physical processes as well as abstract concepts.

The line will pass through the origin, since the equation is satisfied when both x and y are 0. The intercepts of the line on the x-axis and y-axis represent the values of x and y that will make the equation true, regardless of the values of the other variable.

For this equation, the y-intercept is 30, since when x=0, the equation becomes 30(0)+6y=180, and so y=30. This means that if you do not board your dog, you would need to play with it for 30 hours in order to meet the requirement of spending a total of 180 dollars.

The x-intercept is 6 since when y=0, the equation becomes 30x+6(0)=180, and so x=6. This means that if you do not play with your dog, you would need to board it for 6 nights in order to meet the requirement of spending a total of 180 dollars.

Therefore, the graph of the equation 30x+6y=180 shows that it is possible to meet the requirement of spending a total of 180 dollars either by boarding your dog for 6 nights or by playing with it for 30 hours, regardless of the values of the other variable.

The option (A) (7,-7), (-7,-5), (-7,-3), (-7,-1) ordered pair is y a function of x.

What is a function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range.

In a mathematical relation, for a given value of x, there can only be one unique value of y.

It is a requirement that a function must follow.

In option A, the x values are all different, so y is a function of x

In option B, there are two (0,0) and (0,9) which means for x=0 there are two possible values of y, thus y is not a function of x.

In option C, there is a repetition of the x-value, 15, so y is not a function of x

In option D, there is a repetition of the x-value, 13, so y is not a function of x.

So, the correct option is A (7,-7), (-7,-5), (-7,-3), (-7,-1)

Hence, the option (A) (7,-7), (-7,-5), (-7,-3), (-7,-1) ordered pair is y a function of x.

Answer: irrational number

Step-by-step explanation:

Answer:

First, distribute the 3 on the left side of the equation: 3 * 9 + 3 * 4a - 19 = 32

Next, combine like terms on the left side of the equation: 27 + 12a - 19 = 32

Add 19 to both sides of the equation to isolate the variable term: 27 + 12a = 51

Subtract 27 from both sides of the equation to isolate the variable term: 12a = 24

Divide both sides of the equation by 12 to solve for the value of "a": a = 2

So the solution to the equation is "a = 2".

Let F be the number of fragrance samples and L be the number of hand lotion samples.

We know that F + L = 114, since Rika must hand out a total of 114 samples.

We also know that F = (1/3)L and L = (1/4)F, since the number of fragrance samples is 1/3 of the number of hand lotion samples, and the number of hand lotion samples is 1/4 of the number of fragrance samples.

Substituting the second equation into the first equation, we get:

F + (1/4)F = 114

Combining like terms, we get:

(5/4)F = 114

Dividing both sides by (5/4), we get:

F = 92

Substituting this value back into the second equation, we get:

L = (1/4)(92) = 23

Therefore, the system of equations is:

F + L = 114

F = (1/3)L

L = (1/4)F

The solution to this system is F = 92 and L = 23

The value of the ratio x : y : z is 1/2 : /3 : 5/18

From the question, we have the following parameters that can be used in our computation:

x:y = 1/2:1/3 and y:z = 1/5:1/6

Express the ratio properly

So, we have the following representation

x : y = 1/2 : 1/3 and y : z = 1/5 : 1/6

Multiply the ratio y : z = 1/5 : 1/6 by 5/3

So, we have

y : z = 1/3 : 5/18

So, we have

x : y : y : z = 1/2 : 1/3 : 1/3 : 5/18
