What rule would you allow to test weather (x,y) is on line l

Answers

Answer:

Step-by-step explanation:

If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.

Slope of a line passing through two points C(4, 5) and D(8, 10),

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

m = [tex]\frac{10-5}{8-4}[/tex]

m = [tex]\frac{5}{4}[/tex]

Equation of the line passing through C(4, 5) and slope m = [tex]\frac{5}{4}[/tex]

y - y' = m(x - x')

y - 5 = [tex]\frac{5}{4}(x-4)[/tex]

y = [tex]\frac{5}{4}x-5+5[/tex]

y = [tex]\frac{5}{4}x[/tex]

If point B(4, 0) lies on the line CD,

0 = [tex]\frac{5}{4}(4)[/tex]

0 = 5

Which is not true.

Therefore, point B doesn't lie on line CD.

Rectangles P, Q, R, and S are scaled copies of one another. For each pair, decide if the scale factor from one to the other is greater than 1, equal to 1, or less than 1. Four rectangles, labeled P, Q, R and S. Each rectangle is a scaled copy of one another. Ranked in order from least to greatest, the area of the rectangles are as follows: the area of P is equal to S, which are less than the area of Q, which is less than the area of R. From P to Q from P to R from Q to S from Q to R from S to P from R to P from P to S

Answers

I attached a diagram that will aid the understanding of the question.

Firstly, I would love to review what a scale factor is before going into the question.

If you have two shapes that are similar, that is they have corresponding angles, then the scale factor of one to the other is simply the ratio of any two corresponding lengths in the two similar geometric figures.

Looking at these figures in the question, we see that R is an enlargement of the other rectangles while Q is an enlargement of P and S. With this information we can answer the questions:

1. From P to Q, the scale factor greater than one because Q is bigger than P.

2. From P to R, the scale factor is greater than one for the same reason.

3. From Q to S, the scale factor is less than one because S is smaller than Q.

4. From Q to R, the scale factor is greater than one because R is bigger than Q.

5. From S to P, the scale factor is equal to one because they are equal.

6. From R to P, the scale factor is less than one because p is smaller than R.

7. From P to S, the scale factor is equal to one because they are equal.

Step-by-step explanation:

hope this helps :3

if it did pls mark brainliest

plug those numbers into y - y1 = a(x - x1)

so you would get y-(-4) = -6(x - 1) (this is your point-slope form)

simplify to get y + 4 = -6x + 6

simplify more to get y = -6x + 2

then 6x + y =2 (this is your standard form)

Ignore the 1 and the 2. That’s just where you put your answer.

In the equation, we are told that d(t) = 300,000t, where t is the time in seconds and d(t) is the distance in kilometers.

1. In this part of the question, it asks for the distance after 15 seconds. To solve we plug 15 in for t.

d(t) = 300,000(15)

d(t) =  4500000  kilometers

2. In this part of the question, it is asking for time after going 12,000,000 kilometers (twelve million). To solve, we solve for t by dividing 300,000.

12,000,000 = 300,000(t)

Complete question :

Misaki cut some wood for a bookcase she is building.She needs to find how many 1/3 ft boards she can make from a 5 ft board.Explain how to model with fraction bars to solve the problem

Answer:

15

Step-by-step explanation:

Total Size of board = 5 feets

Size of board to be made = 1/3 feets

Number of 1/3 feets board to be made from 5 feets board :

Total size of board / size of board to be made

5 feets ÷ 1/3 feets

5 feets * 3 / 1 feets

= 15

Hence, number of 1/3 feets board that can be made from 5 feets board = 15

Lee sold 16 hats.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Cost of 1 hat= $8

Cost of shirt = $12

Total cost of spirit wear= $272

let the number of hats sold be x

and, let the number of shirts sold be y

So, 8x+ 12y= 272

and, x+ y= 28

Solving the above equations we get

8(28- y) + 12y= 272

224 - 8y + 12y = 272

4y = 48

y = 12

and x= 28- 12 = 16

Hence, Lee sold 16 hats.

A snowbank that is 6 inches deep is melting at a rate of 0.5 inch per hour. Write a linear function to model the scenario and identify the domain and range of the function.

Answers

Answer:

y = -0.5x + 6, Domain [0,12] and Range [0, 6]

Step-by-step explanation:

The slope in a linear function represents the rate of change. Since the amount of snow is decreasing (indicating a negative slope) at 0.5 inches an hour, our slope would be -0.5.

Our y intercept, 6, would be the starting amount of snow. At 0 hours, no snow has been melted.

Our domain is [0,12] these are the x values from where at zero there is 6 inches of snow and at 12 there is 0 inches of snow.

Finally, our range is [0,6]. Since there cannot be no more than 6 or less than 0 inches of snow, our range is [0,6]

AABC is an isosceles triangle with vertex angle B, AB = 2x + 10, AC = 2x,
and BC = 4x - 16. Determine the length of the base of the triangle.

Answers are
A.117 degrees
B.26 degrees
C.15 degrees
D.22 degrees

Answers

Answer:

AC = 26 units

Step-by-step explanation:

Given that,

ABC is an isosceles triangle with vertex angle B such that,

AB = 2x + 10, AC = 2x,  and BC = 4x - 16

Two sides of an isosceles triangle are equal. It means that the angles corresponding to the same sides are equal. It means AB = BC

2x + 10 = 4x - 16

2x-4x = -10-16

-2x = -26

x = 13

AC is the base of the traingle.

AC = 2x

AC = 2(13)

AC = 26 units

So, the base of the triangle is equal to 26 units.

Answers

Answer:

[tex]Vanillas = \$5.6[/tex]

Step-by-step explanation:

Given

[tex]Cup\ Cakes = 24[/tex]

[tex]Cost = \$0.35[/tex] (each)

[tex]Vanilla = \frac{2}{3}[/tex]

[tex]Chocolate = \frac{1}{2}[/tex]

Required

Determine the cost of all vanilla cupcakes

First, we need to determine the number of vanilla cakes.

This is calculated by multiplying the fraction of Vanilla by number of cupcakes

So:

[tex]Vanilla = \frac{2}{3} * 24[/tex]

[tex]Vanilla = \frac{2 * 24}{3}[/tex]

[tex]Vanilla = \frac{48}{3}[/tex]

[tex]Vanilla = 16[/tex]

Since 1 cupcake costs $0.35.

16 would cost 16 * $0.35

So:

Vanillas: ;;;;; [tex]16 * \$0.35 = \$5.6[/tex]

Find the limit !!!!!!

Answers

Answer:

1/8.

Step-by-step explanation:

Use l'Hopitals rule - we find the derivative of top and bottom of the fraction.

Derivative of the numerator = 0 - 1/2 (16 - x)^-1/2  -1

=  1 / [ 2 * (16 - x)^1/2

Derivative of the denominator =  1

When x approaches 0 this is 1 / (2*4)

= 1/8.

Another way to do this is to multiply top and bottom by  4 + (16 - x)^1/2

This  becomes   16 - (16 - x) / x(4 + (16-x)^1/2)

= 1 / (4 + (16 + x)^1/2

When x ---> 0

this = 1 /(4 + 4)

= 1/8.

Negotiation is a process in which two parties find a way to resolve their conflict without the help of outside intervention, or a mediator. Usually, negotiation results in some degree of compromise, with both parties finding something they can give up from their initial stand. However, in fully successful negotiations, neither party compromises their core principles. Rather, after airing the issue calmly and thoroughly, all sides find a solution that they can live with.Here are a few principles that can help you effectively negotiate:Be clear, direct, open, and honest when communicating.Respect the rights of others involved in a discussion.Focus on issues rather than on emotions or on assigning blame.Maintain a neutral or friendly tone:Speaking loudly can convey emotions of anger or frustration that might undercut your communication about an issue.Using a sarcastic tone involves saying one thing but meaning another, which can confuse others and give the impression that you are putting them down, even if you only intend to add humor to the situation.Part ARead these steps for reaching agreement within a conflict. Note that you should only undertake these steps for an issue that is important and involves some change in behavior. Matters of pure opinion, such as which team or movie is better, usually cannot be negotiated.Allow time for any intense emotions to diminish so both people are calm, and meet somewhere that will be calming.Allow both parties to describe their side of the issue. If the problem is not clear, you might have to check your facts or exchange questions with one another.Talk about your feelings with the other person. As you discuss things, keep an open mind and make requests, not demands. You want to involve the other person, not control him or her.Brainstorm potential solutions to the argument. As you brainstorm, resist the urge to judge the solutions until they are all clearly delineated.Select the best solution that you both can agree on. This might require compromises on both sides.If problems arise at any point in the negotiations, agree to reconvene at a later date. Taking a break often allows people to collect their thoughts and keep negative emotions in check.Now, use these tips and any other insights you have to experiment with a scenario. Pick one of these conflict scenarios:Mike's manager, Francine, is concerned that Mike is repeatedly late for work and is therefore not able to complete a full day's work.Ms. Torres is carrying a tray full of drinks and snacks to her family's table at the food court when a stranger's backpack knocks the tray out of her hands and spills its contents.Roommates Click and Clack share cooking and cleaning duties, but Click thinks he's doing more than his fair share of the work.Sisters Haley and Holly share clothes, but Haley thinks that Holly damages them and doesn't remove stains or repair tears.For the scenario you chose:Write a dialogue in which the two parties fail to maintain an assertive exchange (because they resort to aggression, passivity, passive-aggressiveness, or sarcasm).Write a second dialogue in which the two parties succeed in reaching an understanding by making use of effective communication and negation skills. who declared brazils independence from portugal A.
