Answer:  " x = 8 " 
_______________________________
By examining the image attached, we notice that:
_______________________________________________
The 2 (two) particular angles with the following measurements:
_________________________________________________
1)  4x - 2 ;  and: 

2)  3x + 6 ;  
_________________________________________________
are equal; since they are "alternate interior angles" ; since the 2 (two) horizontal lines in the figure are parallel; and since alternate interior angles are equal in measurement.
___________________________________________
The question asks to solve for "x" ;

As such:

  4x - 2  =  3x + 6  ;

Solve for "x"  ; 

Subtract "3" from each side of the equation ; & add "2" to each side of the equation ; 


   4x - 2 =   3x  + 6  ;
  -3x +2 =  -3x  + 2  ;
_________________________
    1x     =            8  ;  
_________________________

   →  x = 8 .
____________________________________
Now, we can check our answer:
<span>____________________________________
</span>      " 4x - 2  =  3x + 6 " ;

  → Plug in "8" for "x" ; to see if both sides of the equation are equal ;

   4(8) - 2  =?  3(8) + 6 ??

  →  32 - 2 =?  24 +  6 ?? 

  →  30 = ? 30 ?  Yes!

Placed them equal to each other.

3x + 6 = 4x - 2                 

6 (+2) = 4x (-3x)

8 = x

plug in x to both of the expressions


3(8) + 6 = 24 + 6 = 30
4(8) - 2 = 32 - 2 = 30  

True

x = 8

hope this helps


B is wrong, because you do not set them equal to 180 ( you set them equal to each other). Next, it is wrong, because they messed up the end too.

hope this helps

Answer:

Option A is correct answer.

Step-by-step explanationa(x-h)x^{2} +k

If the given function is given as

f(x) =a(x-h)x^{2} +k

then vertex is (h,k) and Its domain is set of all real numbers

and range is given to be y ≥k for a>0

So here in the question the equation is given as

3(x-1)x^{2} +2

on comparing the equation with given standard equation

we get a=3 which is greater than zero

h =1 and k=2

therefore vertex is (1,2) ,Domain is set of all real number

and range is y≥2

That is option A is correct!

A rectangular prism has a length of 20 in a width of 2 in and a height of 3 1/4 in the prism is filled with cubes that have edge
Zinaida [17]
You can express the edge lengths in terms of "cubes" or you divide the total volume by the volume of a cube. It works either way.

Edge lengths are
.. 80 cubes by 8 cutes by 13 cubes
so total volume is
.. (80 * 8 * 13) = 8320 cubes


In cubic inches, the volume is
.. (20 in)*(2 in)*(3 1/4 in) = 130 in^3.
The volume of a 1/4-in cube is (1/4 in)^3 = 1/64 in^3.
Then the number of cubes that will fit in the prism is
.. (130 in^3)/(1/64 in^3) = 8320 . . . . cubes

8320 cubes are needed to fill the rectangular prism.

NNADVOKAT [17]
An outlier is a value that is much higher or lower than the rest of the data.
The answer here is .7 because all other values range from 3.1-5.8.

Answer:

1. 350

2. 50

Step-by-step explanation:

1. you can create an equation y = 50x + 200, plug in 3 you and you get  y = 350

2. it says it in the first problem

tip: when doing stuff on canvas, use a different device to look up answers, Canvas can track when you switch tabs

although it cant see where you go, it can still track how many times you left the website/app
