Answer:

7(x+5)-(2xy^2)

that's how you would write the equation

The product of 7 and the sum of x and 5, minus the product of 2, x, and the square of y = (x+5)- 2xy²

Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.

Given:

The product of 7 and the sum of x and 5, minus the product of 2, x, and the square of y.

sum of x and 5 = (x+5)

product of 7 and the sum of x and 5= 7(x +5)

product of 2, x, and the square of y= 2xy²

So, The product of 7 and the sum of x and 5, minus the product of 2, x, and the square of y = (x+5)- 2xy².

Answer:

The correct answer:

The data are continuous because the data can take on any value in an interval. (A)

Step-by-step explanation:

There are two categories of data:

Discrete data: These are data that have specific values that they can take on. There are limits to what values can be assigned to such categories. for example, The number of countries in a continent, there can either be 15 countries, 50 countries 30 countries, etc. There is not a possibility of having 40.56 countries on this kind of list. hence it is a discrete dataset.

Continuous data are data that can take on any value within an interval or on a particular scale of measurement. In this example, the height of the elephant in meters can be 1.5m, 2m, 1.06m, etc. There is no limit to the possibility of the height of an elephant on a meter scale.

Answer:

- 13

Step-by-step explanation:

Step 1:

2c + 5 = c - 8     Equation

Step 2:

c + 5 = - 8   Subtract c on both sides

Step 3:

c = - 8 - 5   Subtract 5 on both sides

Answer:

c = - 13

Hope This Helps :)

Answer:

c=-13

Step-by-step explanation:

2c+5=c−8

Step 1: Subtract c from both sides.

2c+5−c=c−8−c

c+5=−8

Step 2: Subtract 5 from both sides.

c+5−5=−8−5

c=−13

Answer:

∠1=∠9=43°,  ∠2=∠7= 17°,  ∠4=∠5=∠6=60°, ∠3=∠8=120°

Step-by-step explanation:

Given ABC is an isosceles triangle and DBE is an equilateral triangle. we have to find each missing measure.

In triangle ABC,

∠1=∠9    (∵isosceles triangle)

⇒ 4x+3=9x-47

⇒ 9x-4x=3+47 ⇒ 5x=50 ⇒ x=10

Hence, ∠9=∠1=(4x+3)°=4(10)+3=43°

Also, given ΔBDE is an equilateral triangle, and all angle of equilateral triangle are equal.

∴ ∠4+∠5+∠6=180°

⇒ ∠4+∠4+∠4=180° ⇒ 3∠4 = 180° ⇒ ∠4 = 60°

∴ ∠4=∠5=∠6=60°

By exterior angle property, ∠3=∠5+∠6=60°+60°=120°

                                            ∠8=∠5+∠4=60°+60°=120°

In ΔABD, ∠1+∠2+∠3=180°

            ⇒ 43°+120°+∠2=180°⇒ ∠2 = 17°

In ΔABD, ∠9+∠8+∠7=180°

            ⇒ 43°+120°+∠7=180°⇒ ∠7= 17°

Step-by-step explanation:

Answer:

  In the short story “The Landlady,” Roald Dahl’s use of foreshadowing prepared readers well for the end of the story.  He used hints such as describing the outside of the bed and breakfast, giving details of the entry and the bedroom, and also telling the readers about the living room.

  To begin, Dahl used the outside of the bed and breakfast as a use of foreshadowing.  The sign was described to be distinctive. It was portrayed to be luring the boy inside.  Dahl used the opening of the door as a hint also.  He explained that the woman debouched the door open, which would foreshadow that she was abnormal. The woman also had cheap rent at her bed and breakfast.

Next, Dahl moved onto the entry and bedroom setting to give hints to the events to come.  The bed had a hot water bottle in it.  This was meant to make the lady seem like she was waiting for someone soon, since the bottle was still warm to keep the bed heated.  There was also the guest book that had only two other entries.  One was Chris Muholland and the other was Gregory Temple.  These names sounded familiar to the boy and led to his curiosity of who they were.  When the boy remembered where he saw the names before, which was in the newspaper claiming they were missing, it revealed that the men were in the bed and breakfast before they went missing.  This made the reader believe that something was discerning about the situation.

  Dahl finally summed up the story by conveying an image of the living room.  He described a dog and a parrot first.  It turned out the animals were stuffed, and the lady taxidermies them herself.  At this point in the story, the hints are coming together that not everything is adequate about the place.  Her hands were said to be pale, as if they might be lifeless.  Dahl used this to explain that she might have gotten discoloration in her hands from using chemicals in her “work” that she does.  The tea was finally used as a clue.  The lady gave the boy some tea that tasted of bitter almonds.  The use of this information declared that something was in the tea

y= -7x+22/-4

Step-by-step explanation:

Answer:

y=7/4x-11/2

Step-by-step explanation:

Move the Y and x values to separate sides

-4y=-7x+22

divide whatever it takes to make y alone (dived by -4)

y=7/4x-11/2

Answer:

F(-1,2), G(2,4), H(3,7)

Step-by-step explanation:

When you move left to right, it changes the x in (x,y)

When you move up and down, it changes the y in (x,y)

So, if it moves 1 unit to the left, the x decreases by 1

And if it goes 4 units up, the y increases by 4
