Answer:

g= -5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    84-(4*(1-4*g))=0

 84 -  4 • (1 - 4g)  = 0

3.1     Pull out like factors :

  16g + 80  =   16 • (g + 5)

16 • (g + 5)  = 0

4.1      Solve :    16   =  0

This equation has no solution.

A a non-zero constant never equals zero.

4.2      Solve  :    g+5 = 0  

Subtract  5  from both sides of the equation :  

                     g = -5

Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

84 = 4(1 - 4g)

<u>Step 2: Solve for </u><em><u>g</u></em>

  1. Distribute 4:                    84 = 4 - 16g
  2. Isolate <em>g</em> term:                 80 = -16g
  3. Isolate <em>g</em>:                         -5 = g
  4. Rewrite:                           g = -5

<u>Step 3: Check</u>

<em>Plug in g into the original equation to verify it's a solution.</em>

  1. Substitute in <em>g</em>:                    84 = 4(1 - 4(-5))
  2. Multiply:                               84 = 4(1 + 20)
  3. Add:                                     84 = 4(21)
  4. Multiply:                               84 = 84

Here we see that 84 does indeed equal 84.

∴ g = -5 is a solution of the equation.

The sun of three conservative integers is -204. what is the largest integer?
Digiron [165]

let us take the smallest integer as x

the second smallest as x+1

and the largest as x+2

since the sum is -204 we should add all of it to get the answer

therefore x+x+1+x+2=-204

3x+3=-204

3x=-204-3

3x=-207

x=-207/3

x=-69

the largest number is x+2

therefore the largest number is -67

to check whether it is right just add them and check whether we get - 204

therefore -69+-68+-67=

-204

therefore the answer is -67

A new library, L, is to be built at some point along a straight road, R, such that its distance from train station, T, is the sh
andreyandreev [35.5K]

Answer:

Coordinates of the new library is (150, 70)

Step-by-step explanation:

To get the shortest possible distance means that line from point T to point R has to be perpendicular.

Now, the equation of R is given as;

y = x - 80 - - - (1)

For T to be perpendicular, it means it will have a slope equal to the negative reciprocal of line R.

Thus, slope of T is -1/1 = - 1

Thus, using line - slope intercept of y = mx + c, we can find equation of T as;

140 = -1(80) + c

140 = -80 + c

c = 140 + 80

c = 220

Thus, equation is;

y = -x + 220 - - - (eq 2)

Adding equation 1 to equation 2,we have;

y + y = 220 - 80

2y = 140

y = 140/2

y = 70

Putting 70 for y in eq 1 gives;

70 = x - 80

x = 70 + 80

x = 150

Thus;

Coordinate of the new library is (150, 70)

(Essay Question 7 Points)
Irina18 [472]

Well I don't know.
Let's think about it:

-- There are 6 possibilities for each role.
    So 36 possibilities for 2 rolls.
    Doesn't take us anywhere.

New direction:
-- If the first roll is odd, then you need another odd on the second one.
-- If the first roll is even, then you need another even on the second one.
This may be the key, right here !

-- The die has 3 odds and 3 evens.

-- Probability of an odd followed by another odd = (1/2) x (1/2) = 1/4
-- Probability of an even followed by another even = (1/2) x (1/2) = 1/4

I'm sure this is it.  I'm a little shaky on how to combine those 2 probs.

Ah hah ! 
Try this:

Probability of either 1 sequence or the other one is (1/4) + (1/4) = 1/2 .

That means ... Regardless of what the first roll is, the probability of
the second roll matching it in oddness or evenness is 1/2 .

So the probability of 2 rolls that sum to an even number is 1/2 = 50% .

Is this reasonable, or sleazy ?
