Answer is 6/11

Explanation :-

$2( - 3x + 4) = 5x + 2$

Now open left side brackets and multiply 2 with each on left,

$➵ - 6x + 8 = 5x + 2$

Now, bring the common values together for easier calculation.

$➵8 - 2 = 5x + 6x$

$➵6 = 11x$

$➵ \frac{6}{11} = x$

As we cant divide 6/11 , we write it as it is.

Therefore, <em>value of x is <u>6/11</u></em>

The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

<h3>What is relative frequency?</h3>

The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.

Given information-

The card is selected random from the deck of cards.

Total number of trails is 40.

It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.

As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,

$f_r=\dfrac{11}{40}\\f_r=0.3$

In the percentage from,

$f_r={0.3}\times100\\f_r=30$

Thus the relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

Consider 8x2 - 48x = -104.

ki77a [65]

Answer:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$

Step-by-step explanation:

<u>Quadratic Equation Solving</u>

We have the equation:

$8x^2-48x=-104$

Divide by 8:

$x^2-6x=-13$

Now complete the squares so the left side is a perfect square of a binomial:

$x^2-6x+9=-13+9=-4$

Factoring the perfect square:

$(x-3)^2=-4$

Taking the square root:

$x-3=\sqrt{-4}$

The square root of a negative number is an imaginary number:

$x-3=\pm 2\mathbf{i}$

Solving for x:

$x=3\pm 2\mathbf{i}$

The solutions are:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$
