You have two numbers. If you double the first number and add it to the second number, the sum is 10. An equation to represent this situation could be: 2x + y = 10 1) Plot at least five points on this coordinate plane that make the statement and your equation true. What do you notice about the points you have plotted? 2) Using a different color, plot 3 point in the same coordinate plane that do not make the equation true.

Answers

Answer 1

Answer:

(a) See attachment 1

All points lie on the same line

(b) See attachment 2

Step-by-step explanation:

Given

[tex]2x + y = 10[/tex]

Solving (a): Plot 5 points that make the equation, true

First, we calculate the points

Make y the subject

[tex]y = 10 - 2x[/tex]

[tex]x = 0 \to y = 10 - 2* 0 = 10[/tex]

[tex]x = 1 \to y = 10 - 2* 1 = 8[/tex]

[tex]x = 2 \to y = 10 - 2* 2 = 6[/tex]

[tex]x = 3 \to y = 10 - 2* 3 = 4[/tex]

[tex]x = 4 \to y = 10 - 2* 4 = 2[/tex]

So, we will plot the following points

[tex](0,10)\ (1,8)\ (2,6)\ (3,4)\ (4,2)[/tex]

See attachment 1

Notice that all points lie on the same line

Solving (b):

Point (5,7) does not make the equation true, and that is why it lies outside the line

See attachment 2

You Have Two Numbers. If You Double The First Number And Add It To The Second Number, The Sum Is 10.

Describe a sequence of transformation that maps DOG onto CAT

Answers

Sequence of transformation is first moving 5 unit in y axis than mirror image  with y axis.

What would you say about the order of the transformations?

A particular order of transformational events is referred to as a transformational sequence. This indicates that more than one transformation is handled by a series of transformations, and the order in which they happen is important.

What kind of figure can a series of transformations map onto itself?

The line of reflection must pass through the centre point for the figure to map onto itself. The sides of the figure are cut by two lines of reflection. The vertices of the figure are intersected by two lines of reflection. As a result, there are four potential lines of reflection that pass through the center.

Answers

The answers for the two questions is described below:

a. The balance sheet is a financial statement that shows a company's assets, liabilities, and equity at a specific point in time. Each transaction will affect one or more of these categories in different ways:

An increase in assets will increase total assets.

An increase in liabilities will increase total liabilities.

An increase in equity will increase total equity.

The income statement is a financial statement that shows a company's revenues, expenses, and net income over a specific period of time. Each transaction will affect net income in different ways:

An increase in revenues will increase net income.

An increase in expenses will decrease net income.

b. The statement of cash flows is a financial statement that shows the cash flows from operating activities, investing activities, and financing activities over a specific period of time. Each transaction will affect one or more of these categories in different ways:

An increase in cash from operating activities will increase cash flows from operating activities.

An increase in cash from investing activities will increase cash flows from investing activities.

An increase in cash from financing activities will increase cash flows from financing activities.

It is important to note that it can be complex to classify some transactions into one category or another, and it may require more context of the specific transaction and the company's operations.

In order for a triangle to shrink in size but stay proportional to its original size, the scale factor, K, must be between
zero and what?

Answers

In order for a triangle to shrink in size but stay proportional to its original size, the scale factor, K, must be between zero and one.

What is scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

In order for a triangle to shrink in size but stay proportional to its original size, the scale factor, K, must be between zero and 1.

The image is contracted if the scale factor is less than 1 (0< k <1).

The image is enlarged if the scale factor is more than 1 (k > 1).

The image remains the same if the scale factor is 1 (k = 1).

Hence, the scale factor k should be between 0 and 1.

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x

Answers

Answer:

85.1 ft

Step-by-step explanation:

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x

We solve using the Trigonometric function of Cosine

cos y = adjacent/hypotenuse

y = angle = 20°

Adjacent = 80 ft

Hypotenuse = ?

cos 20 = 80/Hypotenuse

Hypotenuse = 80/cos 20

x = 85.134221798 ft

Approximately = 85.1 ft

Length of the slide = 85.1 ft

i need help asap!! please help

Answers

For stuff like this you have to simplify the equation and solve for x.

But since its multiple choice you can just plug in each answer until it makes the equation true.

So here are the equations with n substituted in:

8(8+1)+3=45

7(7+1)+3=45

6(6+1)+3=45

5(5+1)+3=45

Now simplify:

8(8+1)+3=45   becomes  72+3 = 45

6(6+1)+3=45   becomes 42+3=45

5(5+1)+3=45   becomes 30+3=45

Its easiest to start with the highest option given and then go down. Because 8 is already way to high you could skip doing the math for 7 and go straight to 5 and 6.

42+3=45 becomes 45=45

30+3=45 becomes 33=45

So 6 makes this statement true.

After awhile its easy to gauge what numbers will come out to be, so you don't have to do the math for each answer.

Answers

Answer:

Δ ABC is isosceles

Step-by-step explanation:

∠ ABC and ∠ BCE are alternate angles and are congruent , that is

∠ BCE = ∠ ABC = 80°

since DE id a straight line then the angles lying on it sum to 180° , that is

∠ ACD + ∠ ACB + ∠ BCE = 180°

50° + ∠ ACB + 80° = 180°

∠ ACB + 130° = 180° ( subtract 130° from both sides )

∠ ACB = 50°

∠ BAC and ∠ ACD are alternate angles and are congruent , that is

∠ BAC = 50°

then

∠ BAC = ∠ ACB = 50°

Since the 2 base angles are congruent then Δ ABC is isosceles

There are 30 drummers competing in the Battle of the Bands this year. Next year, 5 of the drummers will leave and some new drummers will join the competition. If d is the number of drummers who will join the competition, which expression(s) represent the number of drummers in the competition next year.

Answers

Answer: 25 + d

Step-by-step explanation:

Since there are 30 drummers competing in the Battle of the Bands this year and, 5 of the drummers will leave the following year, the number of drummers left will be gotten by the expression:

= 30 - 5

If If d is the number of drummers who will then join the competition, therefore, the expression that represent the number of drummers in the competition next year will be gotten as:

= 30 - 5 + d

= 25 + d

Therefore, the expression is 25+d.

If Clare distributes all of the beads equally among the 9 buckets, how much will the beads in each bucket weigh?

Answers

The beads in each bucket will weigh 1 pound

How to determine the  weight of the beads in each bucket?

A fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole.

From the graph, we have weights of 0, 1/2, 1 1/2 and 2 pounds.

In order for Clare to distributes all of the beads equally among the buckets, she need to add up weight of the beads and divide by 5.

weight in each bucket = (0 + 1/2 + 1 1/2 + 2)/5 = 5/5 = 1 pound

Thus, each bucket weighs 1 pound
