Which of the following equations could be used to solve the given equation? 9x + 26 + 7x - 17 = 2x + (-3x) + 5x 16x + 9 = 0 16x + 9 = 4x 16x + 11 = 4x

The perimeter of a rectangle is twice the sum of the length and width:
P = 2(L + W)
Since we are given L >= 50 ft and P = 140 ft:
140 >= 2(50 + W)
70 >= 50 + W
20 >= W
Therefore, the width is less than or equal to 20 ft.

(The maximum area is 50 x 20 = 1000 ft^2.)

It takes approximately 6.3 seconds to hit the ground.

We use the equation h(t)=-1/2gt²+v₀t+h₀ to set this up.  g is the acceleration due to gravity, v₀ is the initial velocity and h₀ is the initial height:
h(t) = -1/2(32)t² + 100t + 5
h(t) = -16t² + 100t + 5

We will use the quadratic formula to solve this:


Since a negative amount of time makes no sense, the answer is 6.3.

Area is the space inside a 2d object which looks like A = lw while perimeter is l + w = p
therefore it is false.

I am pretty sure that it is false
but if it is wrong im sorry

The correct answer is:  [D]:  " (- 9, 0) " .

Explanation:
___________________________________________________________

Given the quadratic function in  "factored form" ;  

             →  with "y" substituted for:  "f(x)" — as follows:
___________________________________________________________ 

  →   "  y = (x − 8)(x + 9) "  ;   

  →  Find the "x-intercept" of the equation ; 

                 →   {among the answer choices given} ; 
___________________________________________________________

Note:  The "x-intercept(s)" of an equation refer(s) to the coordinates of the point(s) on the graph of the equation at which the graphed equation crosses the "x-axis".

In other words, the "x-intercept(s)" of an equation refer(s) to the solution of the equation at which: " x = 0 " .
___________________________________________________________
At this point, let us consider our given answer choices:
___________________________________________________________
Note:
____________________________________________________________
Consider the first 2 (two) given answer choices:
____________________________________________________________

Choice:  [A]:  " (0, 8) " ; 

Choice:  [B]:  " (0, -8) " .
____________________________________________________________
→  Both of these are INCORRECT ;

→  {since these 2 (two) answer choices have "non-zero" values as
"y-coordinates" .}.  

Note that by definition, all "x-intercepts" MUST have "y-coordinates" with a value of "0" {zero}.
                                       
→  Both of these are INCORRECT ; since these 2 (two) answer choices have "non-zero" values as "y-coordinates".  

→  Note that by definition, all "x-intercepts" MUST have "y-coordinates" with a value of "0" {zero}.  

Note that:  
___________________________________________________________
Choice:  [A]:  " (0, -8)" ; has "- 8" — [ not: "0" ] — as a: "y-coordinate" ;
  
and that :

Choice:  [B]:  " (0, 8) " ; has " 8 " — [not: "0" ] — as a: "y-coordinate".
____________________________________________________________
This narrows our answer choices to the last 2 (two) remaining choices:
____________________________________________________________

Choice:  [C]:  " (9, 0) "  ;  AND: 
____________________________________________________________

Choice:  [D]:  " (- 9, 0) " .
____________________________________________________________

Note that both of them could be "x-intercepts" ; since both of them have
values of "0" {zero} as "y-coordinates" .
____________________________________________________________
→  Let us examining EACH of the remaining 2 (two) answer choices.  It does not matter the order, but let us start with:  Choice:  [C]:  " (9, 0) " .

→  Consider the original equation:
____________________________________________________________
                      →  " y = (x − 8)(x + 9) " 

→  Note the answer choice given for Choice:  [C]:  " (9, 0)" .

→  This means that when we plug in "9" for "x" , we should get "0" for "y" ; 

→  Let us plug in these values for "x" to see if "0" (for "y") holds true:
                   
                      →  0 =?  (9 − 8)(9 + 9) ?? ; 

                      →  0 =? (1) ( 18) ?? ; 
 
                      →  0 ≠  18 ; 


        →    As such:  Choice:  [C]:  " (9, 0)" — is INCORRECT.
____________________________________________________________

→  At this time, we may assume that:  "Choice [D]:  " (-9, 0)" —  the only remaining answer choice is the correct answer.

→  However, we shall examine this "answer choice" appropriately; as follows:
____________________________________________________________

→  Consider the original equation:
____________________________________________________________
   
                   →  " y = (x − 8)(x + 9) " 

→  Note the answer choice for:  [C]:  " ( - 9, 0)" .

→  This means that when we plug in "-9" for "x" , we should get "0" for "y" ; 

→  Let us plug in these values for "x" ;  to see if "0" (for "y") ;  holds true:
                   
                      →  0 =?  (9 − 8)(- 9 + 9) ?? ; 

                      →  0 =? (1) ( 0) ?? ; 
 
                      →  0 =?  0 ?? ; 

                      →  0  = 0  ! Yes!
___________________________________________________________
As such:  
__________________________________________________________
        →  The correct answer is:  Choice:  [D]:  " (-9, 0)" .
___________________________________________________________

We shall use the z-table to solve for the margin of error. The formula for the margin of error is 
     

The value of z will be taken with the assumption that the significance level is 5%. So, α=0.025. Then .

So, based from this, the margin of error is 
     

The margin of error is about 2%. 

The answer would be 1^2.

To find this, first you divide 6 (numerator) by 6 (denominator) to get 1. Then you subratct the power of 6, from the power of 8, to get 2. Thus getting a final answer of 1^2.

I hope this helps!

6^2
Because 8 - 6 = 2

Given:
x = beginning number of newspapers
24 = sold in the morning
(x - 24) * 2/7 = sold in the afternoon
x * 1/2 = remaining newspapers

5/7 of the remaining newspaper is equal to 1/2 of the original number.

(x - 24) * 5/7 = 1/2 * x 
5x/7 - 120/7 = x/2
5x/7 * 2/2 - 120/7 * 2/2 = x/2 * 7/7
10x/14 - 240/14 = 7x/14
10x/14 - 7x/14 = 240/14
3x/14 = 240/14
14 * 3x/14 = 14 * 240/14
3x = 240
x = 240/3
x = 80

80 - 24 = 56 remaining newspaper in the morning
56 * 2/7 = 16 sold in the afternoon
80 - 24 - 16 = 80/2
40 = 40 remaining newspaper for the day.

24 bucks is what he has left

Starting Amount: $50
$50 - 20 = $30
$30 - 6 = $24

Cesar now has $24 left to his name!
