X/2 -5=20 please give details

Answer:y=3/20+12m+6

Step-by-step explanation: The equation for these types of problems are y=mx+b

the y is the second number, so in the first one the y would be -6, so you replace the y with the -6 and the x with -12

so now the equation is -6=-12m+b

you add the -12m to the other side to make 12m+6=b

now onto the second one, the 9 is the y and the 8 is the x, now the equation is 9=8m+b

this time you replace the b with the equation you got earlier (12m+6=b)

So the equation is 9=8m+12m+6

minus the 6 on both sides

3=8m+12m

add the m's

3=20m

3/20=m

Now you replace the m and the b

y=3/20x+12m+6

Step-by-step explanation:

The parts of the graph where it is going 'up' are where it is increasing.

This is between x = - 4 to x = 0 and between x = 5 to infinity

Expressing in interval form the graph is increasing for

(- 4, 0 ) and (5, ∞ )

Answer:

x = -2

Step-by-step explanation:

( 2x - 1 ) ( x + 3 ) - ( x + 3 ) ( x - 3 ) = x + 2

Expand

x^2 + 5x + 6 = x + 2

x^2 + 5x + 6 - 2 = x + 2 - 2

x^2 + 5x +4 = x

x^2 + 5x + 4 - x = x - x

x^2 + 5x + 4 = 0

-4 / 2 = -2

x = -2

Step-by-step explanation:

the answer 22

From the equation of the elipse, we have that:

The equation of an elipse of center [tex](x_0,y_0)[/tex] has the following format:

[tex]\frac{(x - x_0)^2}{a^2} + \frac{(y - y_0)^2}{b^2} = 1[/tex]

If a > b, we have that:

In this problem, the equation is:

[tex]\frac{(x - 2)^2}{36} + \frac{(y + 3)^2}{24} = 1[/tex]

Thus [tex]x_0 = 2, y_0 = -3, a = 6, b = \sqrt{24}[/tex]

For the major axis:

[tex]x = x_0 \pm a[/tex]

[tex]x = 2 \pm 6[/tex]

[tex]x = 2 - 6 = -4[/tex]

[tex]x = 2 + 6 = 8[/tex]

The endpoints of the major axis are: [tex]x = -4[/tex] and [tex]x = 8[/tex]

For the minor axis:

[tex]y = y_0 \pm b[/tex]

[tex]y = -3 \pm \sqrt{24}[/tex]

[tex]y = -3 - \sqrt{24}[/tex]

[tex]y = -3 + \sqrt{24}[/tex]

The endpoints of the minor axis are: [tex]y = -3 - \sqrt{24}[/tex] and [tex]y = -3 + \sqrt{24}[/tex].

Step-by-step explanation:

1+1=2 is clearly true.

2+3=4 is clearly false.

x if and only if y has a value of true if x and y are both true or both false. It is false otherwise.

So, true if and only if false has a value of false, so the answer is [tex]\boxed{false}[/tex]

Answer:  The correct answer is:  " x = 0 " .

________

Step-by-step explanation:

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Method 1)

________

Subtract "8" from each side of the equation:

________

  → " 8 + 8x − 8 = 8 − 8 " ;

  → On the "left-hand side" of the equation:

          Note the following "like terms" :

            " +8 − 8 = 0 " ;

  →  and we are left with "8x" on the "left-hand side" of the equation.

  → On the "right hand side" of the equation:

         The "(8 − 8)" = 0 ;

________

And we are left with:

  →  " 8x = 0 " ;

________

Now, divide each side of the equation by "8" ;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

  →  8x / 8 =  0/8 ;

to get:

  →  " x = 0 " ;

  →  which is the correct answer.

________

Method 2)

________

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Subtract "8" from each side of the equation; in the following manner:

________

   8  +  8x    =    8 ;

 - 8             =   - 8 ;

_____________

   0  +  8x    =    0 ;

→ We have:  " 0 + 8x = 0 " ;

→ Note: On the "left-hand side" ; we have:

                 " 0 + 8x " ;

  We can simplify this to "8x" ; since the "addition property of zero" states that when "0" is added to any value; the resulting value does not change.

Now, we can bring down the "0" from the "right-hand side" of the equation;

And we can rewrite our equation as:

________

   → " 8x = 0 " ;

Now, divide each side of the equation by "8" ;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

  →  8x / 8 =  0/8 ;

to get:

  →  " x = 0 " ;

  →  which is the correct answer.

________

Method 3)

________

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Divide each side of the equation by "8" ;

________

  → " [tex]\frac{(8 + 8x)}{8} =\frac{8}{8}[/tex] " ;

________

To solve:

________

Note: On the "right-hand side" of the equation:

________

Take note that: " [tex]\frac{8}{8} =[/tex] (8 ÷ 8) = 1 " ;

________

Rewrite the equation as:

________

 →  " [tex]\frac{(8 + 8x)}{8} =1[/tex]  "  ;

________

To solve:

________

Note:  " [tex]\frac{x}{y} = z[/tex] " ;  ↔ [tex]x = z*y[/tex] ; [tex](y\neq 0)[/tex] ;

________

 →  " [tex]\frac{(8 + 8x)}{8} =1[/tex]  "  ;  

 →  From the "left-hand side" of the equation;

      Let us simplify:

________

 →  " [tex]\frac{(8 + 8x)}{8} = \frac{8}{8} + \frac{8x}{8} = 1 + x[/tex] " ;  

Now, bring down the "1" from the "right-hand side" of the equation;

and rewrite the equation:

________

 →  " 1 + x = 1 " ;

Now, subtract "1" from each side of the equation;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

     " 1 + x − 1 = 1 − 1 " ;

  → On the "left-hand side" of the equation:

          Note the following "like terms" :

            +1 − 1 = 0 " ;

  →  and we are left with "x" on the "left-hand side" of the equation.

  → On the "right hand side" of the equation:

         The "(1 − 1)" = 0 ;

  → And we are left with:

      →  " x = 0 " ;

      → which is the correct answer!

Answer:

infinity solution

Step-by-step explanation: because the answer to x could be anything

and number could be Z

Using the theory of Number line in location linear distances, the final position of the ball is 31 yards while the relative position is 6 yards to the right of its initial position.

Final position of the ball = Initial position + distance moved

Final position = (25 yards + 6 yards) = 31 yards

Final position of the ball relative to its starting position :

Therefore, the final position of the ball is 31 yards and it is 6 yards to the right of its starting position.

Answer:

let the amount deposited by each of them in march be m.

in April, Isaiah deposited 210$, this means the amount in his account became m+210

Freddie increased the amount by 15%, this means that the amount of money in his account became: m+0.15m

since both values are still equal, we will equate both equations and solve for m.

m+210 = m+0.15m

0.15m = 210

m = 1400$
