Error Analysis Your friend incorrectly factors the expression below as ​6x(3-4​xy). Factor the expression below correctly. What error did your friend​ make?

18x-24xy

Answers

Answer:

dum

Step-by-step explanation:

Answer: The error made was that the x from 24xy wasn’t taken out. Because if you multiplied 6x and -4xy it would NOT equal -24xy. So what she should done was also 6x(3-4y)



Explanation:

Find the GCF, which is 6x

6x(3-4y)

This is the correct way to factor it.



If I have 150 monster energy drinks and I drink 50, but then get 420 more and drink 6 of them what do you get? Take that number and divide it by how many anime’s you have watched.

Answers

Answer:

5.14e-20

Step-by-step explanation:

150- 50= 100

100+420=520

520-6=514

514 / 10000000000000000000000 = 5.14e-20

:D

Answer:

Step-by-step explanation:

150 - 50 = 100

100 + 420 = 520

520 - 6 = 514

514 ÷ 20 = 25.7

i know i know I haven't watched a lot of anime.

4.) Write the equation of the line shown below? SHOW WORK!

Answers

Answer: y=1/5x-3/5


Explanation:


Use points (3,0) and (-1,-1) to find the slope and y-intercept.

Use y1-y2/x1-x2 to find slope


-1-0/-1-4
=-1/-5
=1/5

So the slope is 1/5


Then use y-y1=m(x-x1) to find the y-intercept.

y-0=1/5(x-3)

y-0=1/5x-3/5

So the equation is y=1/5x-3/5

Step-by-step explanation:

Answer:

X (Blank) = 15

Step-by-step explanation:

To get started: You must subtitude the blank with X/variables, to get solving.

23+15=x+23

Step 1: Simplify both sides of the equation.

23+15=x+23

(23+15)=x+23(Combine Like Terms)

38=x+23

38=x+23

Step 2: Flip the equation.

x+23=38

Step 3: Subtract 23 from both sides.

x+23−23=38−23

x=15 (Final answer)

Stay safe and Merry Christmas! :)

The Taco Hut sells 2 tacos for $2.18, 3 tacos for 3.00, 4 tacos for 3.82, 5 taocs for 4.64. if this patern goes on, how much wound 8 tacos.

Answers

Answer: $7.10



(2,2.18) (3,3) (4,3.82) (5,4.64)

First find the rate of change using y1-y2/x1-x2


3-2.18/ 3-2

=0.82

Next, find the y-intercept or the flat rate

Use the formula y-y1=m(x-x1)

y-3=0.82(x-3)

y-3=0.82x-2.46

y=0.82x+0.54


Next, replace x with 8 for 8 tacos

y=0.82(8)+0.54

y=7.1

What transformation occurred between the set of points below?
A(-8,7) ► A'(-7-8)
B(-4.7) →B'(-7,-4)
C(-6,2)((-2,-6)
A
A reflection over the x-axis
B
Reflection over the y-axis
С
90° clockwise rotation
D 90° counterclockwise rotation

Answers

Given:

A(-8,7) → A'(-7-8)

B(-4,7) → B'(-7,-4)

C(-6,2) → C'(-2,-6)

To find:

The transformation occurred between the set of points above.

Solution:

From the given set of points it is clear that the rule of transformation is

(x,y) → (-y,x)            ...(i)

Because in the given set of points we interchange the x and y coordinates, then we are applying negative sign in the x-coordinate.

If a figure reflection over the x-axis, then

(x,y) → (x,-y)

If a figure reflection over the y-axis, then

(x,y) → (-x,y)

If a figure rotated 90° clockwise, then

(x,y) → (y,-x)

If a figure rotated 90° counterclockwise, then

(x,y) → (-y,x)

Only this rule of transformation is same as (i). So, the figure is rotated 90° counterclockwise.

Therefore, the correct option is D.

Answers

Answer: Scale Factor (Dilation) The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs.

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
