Answer:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Answer:

m = rise/run = 270/20.5 = 13.17

Step-by-step explanation:

Going from (9, 260) to (29.5, 530), we see that the horizontal change (in x) is 20.5 and the vertical change (in y) is 270.  Thus, the slope is

m = rise/run = 270/20.5 = 13.17

Answer:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

There is a common ratio r between consecutive terms

r = [tex]\frac{384}{512}[/tex] = [tex]\frac{288}{384}[/tex] = [tex]\frac{216}{288}[/tex] = [tex]\frac{3}{4}[/tex] , then recursive formula is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex] : a₁ = 512

Answer: 128

Step-by-step explanation:

Sue's average for 9 games of bowling is 108. Therefore, the total scores for the 9 games is:

= 108 × 9

= 972

To have an average of 110 in 10 games, her total score will be:

= 110 × 10

= 1100

Therefore, the lowest score that she can get will be the difference between the values calculated above and this will be:

= 1100 - 972

= 128

Answer:

there are eight lateral faces in prism

There are three lateral faces for a triangular prism.

An edge is a line segment formed by the intersection of two adjacent faces. A vertex is the point of intersection of three edges.

What is the value of this expression when c = -4 and d = 10 ? [tex] \frac{1}{4} [/tex] (c³ + d²)

[tex] \frac{1}{4} [/tex] (c³ + d²) where c = -4 and d = 10

The value of the expression [tex] \frac{1}{4} [/tex] (c³ + d²)

[tex] \frac{1}{4} [/tex] (c³ + d²) [Given expression]

Now, putting the value of c = -4 and d = 10 , we get,

[tex] \frac{1}{4} [/tex] { (-4)³ + (10)² }

[tex] \frac{1}{4} [/tex] ( -64 + 100 )

[tex] \frac{1}{4} [/tex] ( 36 )

[tex] \frac{1}{4} [/tex] × 36

Answer:

The volume of the box is 33.796 cubic inches

Step-by-step explanation:

Given

[tex]Height = 7in[/tex]

See attachment for the base of the prism

Required

The volume of the box

From the attachment, we have:

[tex]a = 1in[/tex] -- side length of the octagon

The area is then calculated as:

[tex]Area = 2 * (1 + \sqrt 2)a^2[/tex]

So, we have:

[tex]Area = 2 * (1 + \sqrt 2)* 1^2[/tex]

[tex]Area = 2 * (1 + \sqrt 2)* 1[/tex]

[tex]Area = 2 * (1 + \sqrt 2)[/tex]

Evaluate the square root

[tex]Area = 2 * (1 + 1.414)[/tex]

[tex]Area = 2 * (2.414)[/tex]

[tex]Area = 4.828[/tex]

The volume is then calculated as:

[tex]Volume = Height * Base\ Area[/tex]

[tex]Volume = 7 * 4.828[/tex]

[tex]Volume = 33.796[/tex]

Keynotes

Using the keynote as a reference, we have the following observation from the attachment:

[tex]\angle c[/tex] and [tex]\angle e[/tex] are opposite

[tex]\angle c[/tex] and [tex]\angle e[/tex] are congruent

Hence:

[tex]\angle c[/tex] and [tex]\angle e[/tex] are vertical

Step-by-step explanation:

Using the Fundamental Counting Theorem, it is found that 360 different computer systems are available.

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

In this problem, the store sells six different computers four different monitors five different printers and three different multimedia packages, hence the parameters are [tex]n_1 = 6, n_2 = 4, n_3 = 5, n_4 = 3[/tex], and the number of systems is:

[tex]N = 6 \times 4 \times 5 \times 3 = 360[/tex]

Answer:

[tex][AB]^2[/tex]

Step-by-step explanation:

Given

Matrices A and B

Required

Represents the square of A and B

The interpretation of the question is that:

The square of the product of A and B

This can be represented as:

The square(product of A and B)

Product means *

So, we have:

The square(A * B)

The square means ^2

So, we have:

[tex][A * B]^2[/tex]

This gives:

[tex][AB]^2[/tex]

Hence, the second option is correct

Answer:

You were right the correct option is

- a > - b

Answer:

y = -3

Step-by-step explanation:

4x – 3y = 17

x = 2

4(2) - 3y = 17

8 - 3y = 17

-3y = 9

y = -3

Answer:

y= -3

Step-by-step explanation:

if x =2, substitute

4(2) - 3y = 17

8-3y = 17

(add 3y to both sides)

8= 17 + 3y

(subtract 17 from both sides)

8-17=3y

-9= 3y

(divide both sides by 3)

-9/3=y

y= -3

Step-by-step explanation:

If x=3, y=7 when x+y=z

z=3+7

z=10

The selling price of each stylus is $6

Percent markup  =

(Selling price - cost price)/cost price *100

Answer:

Step-by-step explanation:

hello :

if x1 and x2 this zero for ax²+bx+c  you have : x1 = 1 /x2  means :x1 × x2 =1

but : x1 × x2 = c /a

in this exercice : a =8  and b = -13  and c = - 4k

so : c/a =-4k/8

so : -4k/8 = 1

-4k = 8        k = 8/-4      k = -2  

this polynomial is : 8x²-13x +8
