What point would you have when (-7, 3) is reflected over the line y=x?
A. (3,-7)
B. (-3,7)
C. (7,-3)
D. (-7,3)

Answer:

original price = $270 new price = $306.99

Step-by-step explanation:

To solve this we first have to find the original price.

13.7 % of the original price is $36.99 from the  question.

We multiply 100 /13.7 * 13.7 /100 to get the 100% value or the original price.

We also multiply 100 /13.7 * 36.99 = $270 to get the original value.

So the original price is $270.

We add $36.99 to the original price to get the new price.

$270 + $36.99 = $306.99

Answer: The area of the enlargement is 315cm.

Step-by-step explanation:

If the picture has 35cm as the area and it has a length of 7cm  then we can find the width by dividing the area by the length.

w= 35/7

w =  5      

So in this care the width of the picture in 5cm.

Now is saying that the picture's length has been enlarge or been dilated to 21 cm. To get from 7cm to 21cm you will have to multiply  by 3.  

In this situation, we will have to multiply the original picture's width by 3 to find it enlargement.

w= 5*3 = 15  

The width is 15cm and the length is 21cm so multiply them to find the area.

A = 15 * 21

A = 315cm

Answer:

c= - (sqr em)/m

Step-by-step explanation:

Answer:

c = ± [tex]\sqrt{\frac{e}{m} }[/tex]

Step-by-step explanation:

Given

e = mc² ( divide both sides by m to isolate c² )

[tex]\frac{e}{m}[/tex] = c² ( take the square root of both sides )

c = ± [tex]\sqrt{\frac{e}{m} }[/tex]

Answer: Hello!

-2-(-5) can also be written as -2 + 5.

When subtracting a negative, you're essentially adding, because you are subtracting a negative value. So we would add 5 to -2.

Answer:

V is 56

Step-by-step explanation:

V= 20+12(3)

V= 20 + 36

V = 56

Hello, please consider the following.

When [tex]x_1[/tex] and [tex]x_2[/tex] are two roots, we can factorise as

[tex]ax^2+bx+c=a(x-x_1)(x-x_2)=a(x^2-(x_1+x_2)x+x_1x_2)=0[/tex]

So for the first equation, we can say that the sum of the zeros is

[tex]\dfrac{a^2+b^2}{2}=\dfrac{a^2}{2}+\dfrac{b^2}{2}[/tex]

and the product is

[tex]\dfrac{a^2b^2}{4}=\dfrac{a^2}{2}\dfrac{b^2}{2}[/tex]

So we can factorise as below.

[tex]4x^2-2(a^2+b^2)x+a^2b^2=(2x-a^2)(2x-b^2)=0[/tex]

And the solutions are

[tex]\boxed{\sf \n\bf \ \dfrac{a^2}{2} \ \ and \ \ \dfrac{b^2}{2}}[/tex]

For the second equation, we will complete the square and put the constant on the right side and take the root.

Let's do it!

[tex]9x^2-9(a+b)x+2a^2+5ab+2b^2=0\\\\9(x-\dfrac{a+b}{2})^2-9\dfrac{(a+b)^2}{4}+2a^2+5ab+2b^2=0\\\\9(x-\dfrac{a+b}{2})^2=\dfrac{9(a+b)^2-8a^2-20ab-8b^2}{4}\\\\9(x-\dfrac{a+b}{2})^2=\dfrac{9a^2+18ab+9b^2-8a^2-20ab-8b^2}{4}\\\\9(x-\dfrac{a+b}{2})^2=\dfrac{a^2+b^2-2ab}{4}=\dfrac{(a-b)^2}{4}\\\\(x-\dfrac{a+b}{2})^2=\dfrac{(a-b)^2}{2^2\cdot 3^2}[/tex]

We take the root, and we find the two solutions

[tex]\begin{aligned}x_1&=\dfrac{a+b}{2}-\dfrac{a-b}{6}\\\\&=\dfrac{3a+3b-a+b}{6}\\\\&=\dfrac{2a+4b}{6}\\\\&\boxed{=\dfrac{a+2b}{3}}\end{aligned}[/tex]

[tex]\begin{aligned}x_1&=\dfrac{a+b}{2}+\dfrac{a-b}{6}\\\\&=\dfrac{3a+3b+a-b}{6}\\\\&=\dfrac{4a+2b}{6}\\\\&\boxed{=\dfrac{2a+b}{3}}\end{aligned}[/tex]

Thank you.

Answer: x = -1 and y = 3

Step-by-step explanation:

[tex]10x - 5y = -25 \\10x + 8y = 14[/tex]

Let's start by solving [tex]10x - 5y = -25[/tex] for [tex]x[/tex]

[tex]10x - 5y=-25[/tex]

Add 5y to both sides

[tex]10x - 5y + 5y = -25+5y \\10x = 5y - 25[/tex]

Now we need to divide both sides by 10

[tex]\frac{10x}{10} = \frac{5y-25}{10}[/tex]

[tex]x = \frac{1}{2} y + \frac{-5}{2}[/tex]

That's not the answer for x. We are not done yet :)

Now we need to substitute [tex]\frac{1}{2} y + \frac{-5}{2}[/tex] for [tex]x[/tex]

[tex]10x + 8y = 14\\10(\frac{1}{2} y + \frac{-5}{2} + 8y = 14[/tex]

Now we need to simply both sides

[tex]13y - 25 = 14[/tex]

Now we need to add 25 to both sides

[tex]13y - 25 + 25 = 14 + 25 \\13y = 39 \\y = \frac{39}{13} \\y=3[/tex]

We have the valuee for y! Now we need to find the value for x

To find the value of x, we need to substitute 3 for y in:

[tex]x = \frac{1}{2} y + \frac{-5}{2} \\x = \frac{1}{2} 3 + \frac{-5}{} \\x = -1[/tex]

Therefore,

The answer is x = -1 and y = 3

Find the multiples of each number:

16:  2, 4, 8, 16

24: 2, 3, 4, 6, 8, 12

Now for the greatest number of bags, use the greatest common factor.

The greatest common factor is 8

16 / 8 = 2

24 / 8 = 3

She can make 8 bags which contains 2 stickers and 3 bracelets in each bag.

Answer:

8 party bags.

Step-by-step explanation:

We are dealing with greatest common factor.

16= 1,2,4,8

24=1,2,3,4,6,8,12

Now we see the greatest common factor is 8 bags. Since we know its 8 bags, we can make this conclusion. 16/8= 2 stickers each bag. 24/8=3 bracelets each bag. So, the greatest number of party bags she can make is: 8 bags.

More info: 2 stickers each. 3 bracelets each.

Hope this helps! :)

The required quotient would be 66 8/25 or 66.32 which is determined by dividing 1,658 by any divisor 25.

A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 12×2 = 24

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have to determine the quotient.

⇒ 1,658 ÷ 25

Apply the Division operation, and we get

⇒ 1,658 / 25

⇒ 66.32

⇒ 66 8/25

Therefore, the required quotient would be 66 8/25 or 66.32.

Step-by-step explanation:

We are learning about perimeter.

Look for the formula of the perimeter,

P = a + b + c

The question states "The longest side is twice that of the shortest side."

A is the longest side while b is the shortest side.

The shortest side equation would be found below :

6.2 = 2c

c = 3.1

Making a completion of the longest side :

14.5 = 6.2 + 3.1 + b

Answer: B. Start with 45 tiles and separate them into 15 same-sized groups

Step-by-step explanation:

In this case, 45 is divided by 15

#1 we should start with the total amount (dividend) that is going to be divided which is 45

#2 we should separate the dividend into the divisors amount which is 15

with all the steps, we will get the 3 groups of 15 which will be the answer

Step-by-step explanation:

We can find the slope using the slope formula

m = (y2-y1)/(x2-x1)

    = ( 8-7)/(9-6)

   = 1/3

Answer:

[tex] \frac{1}{3} [/tex]

Step-by-step explanation:

Step 1: Use slope formula

[tex]m= \frac{y2 - y1}{x2 - 1} [/tex]

[tex]m = \frac{8 - 7}{9 - 6} [/tex]

[tex]m = \frac{1}{3} [/tex]

Answer: B & D

Step-by-step explanation:

In this scenario we want to come out with a situation where both sides are in an even playing field, as the equation solves to zero.

If a diver is 35 feet below water (-35) and he comes up to breathe, he goes up 35ft (35) meaning he is at the surface (0).

If Manuel is in debt for 35$ (-35) and then he pays off the 35$ (+35) then he is even (at 0).

Answer:

A diver is 35 feet below the surface of the water and then comes up to the surface.

Answer:

148

Step-by-step explanation:

a straight line is always 180 degrees. therefore if you subtract 32 from 180 you are left with 148 degrees.

hope this helps

Answer:

D

Step-by-step explanation:

∠ ABD and ∠ ABC are adjacent angles and are supplementary, thus

∠ ABD + 32° = 180° ( subtract 32° from both sides )

∠ ABD = 148° → D

Answer:

m<EBD = 130 degrees

Step-by-step explanation:

We can say that Line EC is bisected by Line AD at point B.  The angle CBD = 50 degrees is a supplement of the bisected line EC.  With this in mind we can say:

EBD + CBD = 180

And we can solve for EBD:

EBD + CBD = 180

EBD + 50 = 180

EBD = 130

So the measure of angle EBD is 130 degrees.

Cheers.

Answer:

130°

Step-by-step explanation:

You need the remaining angle. 50° and the missing angle make up 180°. Therefore, you need to subtract 50 from 180. 180 - 50 = 130. Hence, the missing angle is 130°.

Answer:

x is greater than or equal to -4 but less than or equal to 4

Step-by-step explanation:

The "domain" is all of the x values on the line. But there are an infinite amount of x-values there, so it must be written as that.

Answer:

See below.

Step-by-step explanation:

The domain is simply the range of x-values the graph encompasses. From the given graph, we can see that the graph stretches from x=-4 to x=+4.

However, note that the graph does not include -4 since the point is an open circle. However, it does include +4 since the point is a closed circle. Therefore, the domain of this graph is:

In interval notation:

[tex](-4,4][/tex]

(Parenthesis on the left because -4 is not included. Brackets on the right because +4 is included.)
