Answer:

x = -2

Step-by-step explanation:

6 - 2(x + 6) = 3x +4

6 -2x - 12 = 3x + 4

6 - 12 - 2x = 3x + 4

-6 -2x = 3x +4

-6 - 4 - 2x = 3x + 4 - 4

-10 -2x = 3x

-10 -2x + 2x = 3x + 2x

-10 = 5x

-10 / 5 = 5x/5

x = -2

I hope this helps!!

Answer:

x = -2

Step-by-step explanation:

6 - 2(x + 6) = 3x + 4

Step 1: Multiply -2(x+6)

6 - 2(x + 6) = 3x +4

6 - 2x - 12 = 3x + 4

Step 2: Distribute the left side ("6 - 2x - 12")

-2x - 6 = 3x + 4

Step 3: Add "-2x" to both sides.

-2x - 6 = 3x + 4

+2x +2x

-6 = 5x + 4

Step 4: Subtract "4" from both sides.

-6 = 5x + 4

-4 -4

-10 = 5x

Step 5: Divide both sides by "5" to get x alone.

-10 = 5x

What are the coordinates of the turning point for the function f(x) = (x - 1)3 - 3? A. (-1, -3)

Naddik [55]

ANSWER

The turning point is

$(1,-3).$

EXPLANATION

The function given to us is

$f(x) = (x - 1) ^{3} - 3$

At turning point,
$f '(x) = 0$

So we need to differentiate the given function and equate it to zero.

We using the chain rule of differentiation, we obtain,
$f '(x) =3 (x - 1) ^{2}$

We equate this to zero to obtain,

$3 (x - 1) ^{2} = 0$

We divide through by 3.

$(x - 1) ^{2} = 0$

We solve for x to get,

$x - 1 = 0$

$x = 1$

We substitute this x-value in to the function to obtain the corresponding y-value of the turning point.

$f(1) = (1- 1) ^{3} - 3$

$f(1) = 0 - 3$

$f(1) = - 3$

Therefore the turning point is

$(1,-3)$

C is the correct answer.

How to solve 6x+5x-4=2x-8

solniwko [45]

6x+5x-4=2x-8~~~First we simplify(add 6x and 5x)
11x-4=2x-8~~~Now add 4 to both sides
+4 +4
11x=2x-4~~~~Remove 2x from both sides now.
-2x -2x
9x=-4~~~~Now divide by 9x
÷9x ÷9x

x= -4/9
