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.

Sum of two digit number is9.When we interchange the digits it is found that the resulting new number becomes twice the other num
ruslelena [56]

Answer:

4 and 5

Step-by-step explanation:

Let the numbers be x and y

If their sum is 9, hence;

x + y = 9 ....1

When reversed

10y+x = 2(10x+y)

10y+x = 20x + 2y

10y - 2y = 20x - x

8y = 19x

y = 10x/8 ...2

Substitute equation 2 into 1;

From 1;

x+y = 9

x +(10x/8) = 9

18x/8 = 9

18x = 72

x = 72/18

x = 4

Since x+y =9

y = 9-x

y =9-4

y = 5

Hence the numbers are 4 and 5

Simplify 16^-4 by making the exponent positive
Scorpion4ik [409]
Whenever we have a negative exponent, that means that the function should be in the denomenator. then the exponent will be positive.

Example

16^-4 = 1/(16^4)

9. What is the slope of the line through the points (-2, -1) and (4, 3)?
Fofino [41]

Step-by-step explanation:

given points,

(-2, -1) and (4,3)

we know,

slope of line = y_2 - y_1/ x_2 - x_1

x_1 and y_1 = -2 , -1

x_2 and y_2 = 4 , 3

according to the formula

3 - (-1)/4 - (-2)

→ 3 + 1/4 + 2

→ 4/6

→ 2/3

or (2,3)

therefore, slope of the given line is (2,3).

Hope this answer helps you dear!

A parabola has the equation –5x2 + 30x – y – 34 = 0. Which equation is that of the parabola in vertex form?
frozen [14]
We can complete the square to get a standard form quadratic into vertex form. First, add Y and 34 to the right side of the equation. You’ll get -5x^2 + 30x = y + 34.
Next, you need to factor out a -5 from the left side, so you’ll get -5(x^2 -6x) = y + 34. Then, complete the square on the left. You’ll get -5(x-3)^2 = y - 11. Finally, add 11. The answer is y = -5(x-3)^2 + 11
