Well you see that they are all 2 so go on to the next part you have two 2.9 and two 2.8  . since the 2.8 s are smaller you continue with them and you have a 2.83 and a 2.84; 3 is smaller than 4 so the 2.830 will be the least and the 2.841 will come next. now you go back to those 2.9 s and continue. you have a 2.91 and a 2.90. 0 is less than 1 so 2.909 will come next and 2.912 will be last .

2.830; 2.841;  2.909; 2.912

Mount mckinley in alaska is 20,320 feet above sea level. Mauna kea in hawaii is 13,796 feet above sea level. How many more feet
strojnjashka [21]

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above:

- Mount Mckinley is 20,320 feet above sea level.

- Mauna kea is 13,796 feet above sea level.

2. Then, you only need to substract both quantities to solve the exercise, as following:

20,320ft-13,796ft=6,524ft

Therefore, as you can see, the answer is: 6,524 feet.

Which inequality is equivalent to x-6/x+5≥x+7/x+3?
yawa3891 [41]
To find equivalent inequalities you have to work the inequality given.

The first step is transpose on of sides to have an expression in one side and zero in the other side:

  x - 6        x + 7
--------- ≥  --------
  x + 5       x + 3

=>

  x - 6          x + 7
--------- -  --------   ≥ 0
  x + 5       x + 3

=>

 (x - 6) (x + 3) - (x + 7) (x + 5)
--------------------------------------- ≥ 0
          (x + 5) (x + 3)

=>

 x^2 - 3x - 18 - x^2 - 12x - 35
--------------------------------------- ≥ 0
         (x + 5) (x + 3)

           15x + 53
-     -------------------   ≥ 0
       (x + 5) (x + 3)

That is an equivalent inequality. Sure you can arrange it to find many other equivalent inequalities. That is why you should include the list of choices. Anyway from this point it should be pretty straigth to arrange the terms until making the equivalent as per the options.

Alvin's age is two times Elga's age. The sum of their ages is 84 . What is Elga's age?
son4ous [18]
Alvin's age + Elga's age = 84
2R + R                             = 84 
3 R                                   = 84
3/ 3 R = 84/ 3 
R = 28 
Elga's age is 28

Graph the equation y = x2 + 8x + 12 on the accompanying set of axes. You must
UkoKoshka [18]

Answer:

Step-by-step explanation:

Roots:  set y = x^2 + 8x + 12 = 0 and solve for x:  x + 6 = 0, so x = -6 is one root.  The other is x = -2.  The corresponding points are (-6, 0) and (-2, 0).

y-intercept:  Let x = 0.  Then y = 12.  The y-intercept is (0, 12).

Axis of symmetry:  x = -b / (2a) => x = -8/(2*1) = -4:  x = -4

Vertex y-value:  evaluate y at x = - 4:  (-4)^2 + 8(-4) + 12 = -4:    (-4, -4)

Arbitrarily chosen x value:  x = 1 => 1^2 + 8(1) + 12 = 21:     (1, 21)

The five points are:  (-6, 0) and (-2, 0), (0, 12), (-4, -4), (1, 21).  The vertex is (-4, -4).  The parabolic graph opens UP.
