Answer:

The midpoint is (3/2,0)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinate of the endpoints and divide by 2

(7+-4)/2 = 3/2

To find the y coordinate of the midpoint, add the y coordinate of the endpoints and divide by 2

(-2+2)/2 = 0

The midpoint is (3/2,0)

Anyone know quadratics

When competing the square, you want to have
${b}^{2}$
at the end, and using the fact that the x term and coefficient are really
$2bx$
, we see that the third option is the most efficient way to start

When the positive integer x is divided by 9, the remainder is 5. What is the remainder when 3x is divided by 9?

NARA [144]

Answer:

Step-by-step explanation:

Let n represent the quotient of the number.

We have been given that when the positive integer x is divided by 9, the remainder is 5. We can represent this information in an equation as:

$x=9n+5$

When 3x is divided by 9:

$3x\Rightarrow 3(9n+5)$

$27n+15$

Now, we need to break 15 into two numbers as:

$27n+9+6$

Now, we will factor out 9 as:

$9(3n+1)+6$

Therefore, the remainder will be 6.

HELP PLEASEEEEEEEEEEEEEEEEEEEEEEEEE

Answer:

The solution set to the absolute value is:

$S = \{x \in \mathbb{R}| x \ge 0\}$ or $S = [0, +\infty)$

Negative real numbers are not included in the solution set, as for $x < 0$ , $|x| = - x$ .

Step-by-step explanation:

From Mathematics, we know that absolute values are defined by the following characteristics:

1) For $x \ge 0$ , $|x| = x$

2) For $x < 0$ , $|x| = - x$

Then, if $|x| = x$ , then the solution set to the absolute value is:

$S = \{x \in \mathbb{R}| x \ge 0\}$ or $S = [0, +\infty)$

Negative real numbers are not included in the solution set, as for $x < 0$ , $|x| = - x$ .
