If two or more points are collinear they lie on the same plane.

Collinear points are points that lie on the same straight line. In other words, if three or more points are collinear, they can be connected by a straight line.

Collinear points are important in geometry and are used in many geometric proofs and constructions. The concept of collinearity is also used in other fields, such as physics and engineering, where it is used to describe the motion of objects along a straight line or to define the direction of forces acting on an object.

Option D is not justified because living in water doesn't necessarily mean that the snakes are fish. This logical fallacy is known as the undistributed middle. Options A, B, and C present logically justified conclusions.

The conclusion that is not justified by the previous pair of statements is found in option D: 'All fish live in the water. Some snakes live in the water. Some snakes are fish.' In this scenario, the fact that some snakes live in the water does not logically lead to the conclusion that those snakes are fish. This is because belonging to the category 'fish' is not determined simply by living in water. Therefore, the conclusion is not supported by the given premises.

In contrast, for options A, B, and C, the conclusions are logically justified by the premises:

Each of these sets uses deductive reasoning to draw conclusions that are supported by the premises. However, option D is an example of a logical fallacy known as the undistributed middle, leading to an erroneous conclusion.

The sides of the right angle triangle are 20, 48, and 52.

We have given that,

The hypotenuse of a right triangle is 8 feet less than three times the shorter leg and the longer leg is 8 feet more than twice the shorter leg.

Suppose the shortest leg is x, the hypotenuse is then 3x-8, and the longer leg is 2x+8

We use the Pythagorean theorem

[tex]hypotenous^2=side^2+side^2[/tex]

Therefore by using Pythagorean theorem

[tex]x^2+(2x+8)^2=(3x-8)^2\\x^2+(4x^2+32x+64)=(9x^2-48x+64)\\4x^2-80x=0[/tex]

x=0 or x=20

So the sides are 20, 48, and 52.

The function rule in slope-intercept form is y = 3x + 9.

The function rule in slope-intercept form is given by the equation y = mx + b, where m represents the slope of the line and b represents the y-intercept.

In this case, the given y-intercept is 9, so b = 9.

The slope of the line is 3, which means that for every increase of 1 on the horizontal axis (x-axis), there is a rise of 3 on the vertical axis (y-axis). Therefore, m = 3.

Putting these values into the slope-intercept form, we get the function rule to be y = 3x + 9.

Answer:

So, the point-slope form of the equation that represents the line passing through the points [tex]\((-6,4)\) and \((2,0)\)[/tex] is:

[tex]\[ y - 4 = -\frac{{1}}{{2}}(x + 6) \][/tex]

Explanation:

To find the equation of the line passing through the points [tex]\((-6,4)\) and \((2,0)\)[/tex] , we can use the point-slope form of the equation of a line:

[tex]\[ y - y_1 = m(x - x_1) \][/tex]

Where [tex]\((x_1, y_1)\)[/tex]  is a point on the line, and [tex]\(m\)[/tex] is the slope of the line.

First, let's find the slope [tex]\(m\):[/tex]

[tex]\[ m = \frac{{y_2 - y_1}}{{x_2 - x_1}} \][/tex]

Using the coordinates of the given points:

[tex]\[ m = \frac{{0 - 4}}{{2 - (-6)}} \][/tex]

[tex]\[ m = \frac{{-4}}{{2 + 6}} \][/tex]

[tex]\[ m = \frac{{-4}}{{8}} \][/tex]

[tex]\[ m = -\frac{{1}}{{2}} \][/tex]

Now that we have the slope, let's choose one of the given points to plug into the point-slope form. We'll use [tex]\((-6,4)\):[/tex]

[tex]\[ y - 4 = -\frac{{1}}{{2}}(x - (-6)) \][/tex]

[tex]\[ y - 4 = -\frac{{1}}{{2}}(x + 6) \][/tex]

[tex]\[ y - 4 = -\frac{{1}}{{2}}x - 3 \][/tex]

Now, let's simplify and put the equation in slope-intercept form:

[tex]\[ y = -\frac{{1}}{{2}}x - 3 + 4 \][/tex]

[tex]\[ y = -\frac{{1}}{{2}}x + 1 \][/tex]

Given

Tom and Martin both worked 9 hours this week and sold $360 worth of meals

Tom's percent of tips was 15% while Martin's was 20%

Find out the most money this week between Tom and Martin

To proof

In this question take two cases

FIRST CASE

Martin worked 9 hours

sold worth of meals = $360

Martin's percent of tip = 20%

First convert 20% in decimal form

= [tex]\frac{20}{100}[/tex]

= 0.20

than the equation becomes

Martin makes money = 9 × 2.50 + 0.20 × 360

                                   = 22.5 + 72

                                   = $ 94.5

SECOND CASE

Tom worked 9 hours

Tom's percent of tips = 15%

sold worth of meals = $360

First 15 % is written in decimal form

= [tex]\frac{15}{100}[/tex]

= 0.15

than the equation becomes

Tom  makes money = 9 × 2.15 + 0 .15× 360

                                =  19.35 + 54

                                = $ 73.35

Thus martin makes money is $94.5

Thus tom makes money is $73.35

Hence Martin makes more money than tom

Hence proved

Answer: Tom made more money than Martin

To determine the number of units produced by Assembly Line A when Line B produces 555 units, we use the ratio of their production rates (45/37) to find that Assembly Line A would produce 675 units.

The question asks how many units Assembly Line A produces when Assembly Line B produces 555 units, given that Line A produces 45 units in the same time that it takes Line B to produce 37 units. To find the answer, we can use the concept of ratio and proportion.

Since Line A produces 45 units at the same time Line B produces 37 units, we have a ratio of 45/37. With Line B producing 555 units, we can set up a proportion to find how many units Line A produces:

45/37 = x/555

Multiplying both sides of the equation by 555, we get:

x = (45/37) * 555

Calculating the value of x gives us:

x = 675

Therefore, Assembly Line A produces 675 units in the same time that Assembly Line B produces 555 units.

Answer: $5,725

Step-by-step explanation:

Given: The cost of home = $205,000

If there is no down payment, then the mortgage amount = $205,000

We know that one point costs 1 % of mortgage amount .

2 points = 2 % of the mortgage amount =[tex]0.02\times205,000=\$4,100[/tex]

[tex]\text{Closing costs=}\text{cost of points + appraisal fee+processing fee+ title fee}[/tex]

[tex]=\$4,100+\$450+\$575+\$600=\$5,725[/tex]

Hence, her total in closing costs = $5,725.

To find the intervals over which a function is increasing, you need to find its derivative, set it greater than 0 and solve for x. The solutions give the intervals where the function is increasing.

In mathematics, to find the intervals over which a function is increasing, you first need to find its derivative. The derivative of a function at a certain point gives the slope of the tangent line at that point. If the derivative is positive, the function is increasing. If it's negative, the function is decreasing.

For example, let's say we have a function f(x) = x^3 - 3x. The derivative of this function is f'(x) = 3x^2 - 3. To find the interval where the function is increasing, we set the derivative greater than 0 and solve for x: 3x^2 - 3 > 0. The solution to this inequality gives the intervals over which the function is increasing .

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

-3 is a zero of P(x) = 2x^3 + 3x^2 - kx - 27

so,

We can just input the value of -3 into the equation to find value of k.

now, we get,

0=2(-3)^3 + 3(-3)^2 +3k -27

27= -54 +27 + 3k

27= -27 = 3k

27+27 = 3k

Lines can be parallel, perpendicular or have no relationship at all.

The equation of the line is: [tex]\mathbf{y = -3x + 14}[/tex]

First, we calculate the slope of: [tex]\mathbf{y = \frac x3 - 1}[/tex]

A linear equation is represented as:

[tex]\mathbf{y = mx + c}[/tex]

Where:

m represents the slope

So, by comparison:

[tex]\mathbf{m = \frac 13}[/tex]

From the question, we understand that the required line is perpendicular to [tex]\mathbf{y = \frac x3 - 1}[/tex]

This means that, the slope (m2) of the required line is:

[tex]\mathbf{m_2 = -\frac 1m}[/tex]

So, we have:

[tex]\mathbf{m_2 = -\frac 1{1/3}}[/tex]

[tex]\mathbf{m_2 = -3}[/tex]

The equation of the line is:

[tex]\mathbf{y = m_2(x - x_1) + y_1)}[/tex]

Where:

[tex]\mathbf{(x_1,y_1) = (4,2)}[/tex]

So, we have:

[tex]\mathbf{y = -3(x - 4) + 2}[/tex]

Open bracket

[tex]\mathbf{y = -3x + 12 + 2}[/tex]
