Hope this helps
Answer 2
x^2 - 8x + y^2 - 4y = 5
(x^2 - 8x + 16) + (y^2 - 4y + 4) = 5 + 16 + 4
(x - 4)^2 + (y - 2)^2 = 25 = 5^2

Answer:

A & C

Step-by-step explanation:

You're looking for rational numbers that are also integers, but because (as the figure shows) ALL integers are already rational, you only have to worry about the integer part. An integer is a whole number, positive or negative. So, you need to simplify each element of each set (the numbers inside the curly braces) to see if they're whole.

A - The square root of 100 is just 10 or -10, divided by -2 is -5 or 5. 4, -2, 5, and -5 are all integers.

B - Wrong because 4/3 is not a whole number

C - 16/4 is just 4, and the square root of 49 is 7 or -7. 4, -6, 2, 7, & -7 are all integers.

D - Wrong because 27/2 is not a whole number

Suppose Felipe has 9.24 pounds of seed if it takes 6.6 pounds of seed to plant on acre of grass how many acres of grass can be planted?

Answers

Answer:

1.4 acres of grass can be planted.

Step-by-step explanation:

He has 9.24 pounds of seeds.

If one acre of grass needs 6.6 pounds of seeds we can divide 9.24 pounds by 6.6 pounds to find how many acres of grass he can plant.

9.24 lbs × [tex]\frac{1acre}{6.6 lbs}[/tex] = 1.4 acres

Quadrilateral ABCD has both reflection and rotation symmetry. What type of quadrilateral could it
be? Show or explain.

Answers

Answer:

Rhombus

Step-by-step explanation:

So if |AB| = |BC| then ABCD is a rhombus and has a second line of reflective symmetry, namely \overleftrightarrow{BD}. Quadrilateral ABCD is what is called a kite.

Since ℓ contains two vertices of ABCD the other two must be reflections of one another about ℓ. In the picture ℓ goes through A and C and D=rℓ(B). So rℓ interchanges AD¯¯¯¯¯¯¯¯ and AB¯¯¯¯¯¯¯¯ and also interchanges CB¯¯¯¯¯¯¯¯ and CD¯¯¯¯¯¯¯¯. So if |AB|=|BC| then ABCD is a rhombus and has a second line of reflective symmetry, namely BD←→. Quadrilateral ABCD is what is called a kite. Note that we have implicitly used the fact that ABCD is convex: without this hypothesis, the vertex C could be reflected over BD←→, giving a non convex quadrilateral with exactly one line of symmetry.

Rectangle has rotational and reflectional symmetry.

What is Quadrilateral?

A quadrilateral is a polygon having four sides, four vertices and four angles.

Given that;

Quadrilateral ABCD has both reflection and rotation symmetry.

Now,

A rectangle ABCD has a reflection symmetry because it has two line of symmetry.

And, Rotational symmetry is defined as the number of times an object is exactly identical to the original object in a complete 360° rotation.

So, Rectangle ABCD has rotational symmetry.

Thus, Rectangle has rotational and reflectional symmetry.

The total cost after sales tax to fix Azar’s computer is represented by the expression 0.08 (55h) + 55h, where h represents the number of hours it takes to fix Azar’s computer.


What percentage sales tax is Azar being charged? Explain your answer using 1-2 sentences


What part of the expression represents the dollar amount of sales tax Azar must pay?

Answers

Answer:

these are 5 points look clearly.XD

The percentage sales tax is 8%.

The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).

Given,

The total cost after sales tax to fix Azar’s computer is represented by the expression:

- 0.08 (55h) + 55h

where h represents the number of hours it takes to fix Azar’s computer.

We need to find out what percentage of sales tax is Azar being charged.

and what part of the expression represents the dollar amount of sales tax Azar must pay.

What represents sales taxes?

It is mostly represented by a percentage.

We have,

100% = 100/100 = 1

50% = 50/100 = 1/2 = 0.5

25% = 25/100 = 1/4 = 0.25

20% = 20/100 = 1/5 = 0.2

We have,

- 0.08 (55h) + 55h

The sales tax is also charged according to the number of hours so,

In the expression 0.08 can be written as a percentage.

0.08 = 8 /100 = 8%

The percentage sales tax is 8%.

Now,

0.08 55(h) means the sales tax Azar must pay.

For 1 hour,

0.08 x 55 = 4.4 is the sales tax.

For 2 hours,

0.08 x (55x2) = 0.08 x 110 = 8.8.

And so on,

So,

The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).

Thus,

The percentage sales tax is 8%.

The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).

1: 12 * [tex]10^{9}[/tex]

         We can easily tell this is the answer here as 12 is larger than 4. They are both being multiplied by the same power of 10, so we can ignore that part and still tell which is larger.

2: 3 * [tex]10^{12}[/tex]

         Same here, we can easily tell this is the answer here as 3 is larger than 1.5. They are both being multiplied by the same power of 10, so we can ignore that part and still tell which is larger.

3: 6 * [tex]10^{5}[/tex]

         This one is slightly more complicated than the other two, but still not to difficult when you know what you're doing.

          A tip: 10 to the fourth power ([tex]10^{4}[/tex]) is 10,000. Aka, a 1 with four zeros!

For the first one, 20 has a zero, so we can take it and put it onto the 10th power. We know have:

2 * [tex]10^{5}[/tex] and 6 * [tex]10^{5}[/tex]

         Using the same method as #1 and #2, we can tell that 6 * [tex]10^{5}[/tex]  is the answer here!

The value of xis
and the value of yis

Answers

Answer:

x = -8/3

y = 5

Step-by-step explanation:

Finding the equation of the line:

y = 3x +c

Substituting (-2,5) into 'y=3x+c':

5 = -6 + c

c = 11

Hence,

y = 3x + 11

For finding x:

Substituting (x, 3) into 'y = 3x +11':

3 = 3x + 11

3x = -8

x = -8/3

For finding y:

Substituting (-2, y) into 'y = 3x + 11':

y = -6 + 11

y = 5

Objective - This is an exercise to get comfortable with applying the language of art as well as the steps of the Art Analysis ChartActions (summarized below).

You must include in this exercise four short, clearly separated paragraphs (2-3 sentences) consisting of the concerns printed in bold:

1. description of the chosen image (include the image information: title, artist's name, year, medium, etc.) and say what you see.

2. analysis of what you see by saying what each element is achieving (e.g. "converging lines are used to draw our attention to the focal point.")

3. interpretation of the image by saying what the work is about and what it means.

4. evaluation of the image by talking about where you think the "value" lies in your chosen image, and explain why. The term value here is not in the context of light or dark as in formal attributes. It refers to what is significant in the work of art you are analyzing, and how successful or unsuccessful it has been executed. Evaluation here is an exercise in reasoning/arguing based on your previous three paragraphs.

Combine like terms

9x + 18 = 180

Subtract 18 from both sides

9x = 180 - 18

9x = 162

x = 162/9
