2 answers:

7 0

The equation given in the question is
- 5|x + 1| = 10
- 5x - 5 = 10
- 5x = 10 + 5
-5x = 15
x = - 3
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option. I hope that this is the answer that has actually come to your desired help.

What is the midpoint of AB?

Citrus2011 [14]

Answer:

$(-4, -\frac{1}{2})$

Step-by-step explanation:

Hi there!

We are given the line segment, with the end points AB

The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).

We want to find the midpoint of the line segment AB

The midpoint formula is given as $(\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are coordinates

We have two coordinates, which is what we need, but let's label their values to avoid any confusion:

$x_1=-5\\y_1=-4\\x_2=-3\\y_2=3$

Now substitute those values into the formula:

$(\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})$

$(\frac{-5+ -3}{2}, \frac{-4+ 3}{2})$

Now simplify the numerator and denominator

$(\frac{-8}{2}, \frac{-1}{2})$

Simplify again:

The midpoint is (-4, $-\frac{1}{2}$ )

Hope this helps!

Based on daily measurements, Bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds, while Mary's weight h

soldi70 [24.7K]

Answer:

Step-by-step explanation:

The coefficient of variation CV is given by the following formula:

$CV = \frac{\sigma}{\mu}$

In which $\sigma$ is the standard deviation and $\mu$ is the mean.

Bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds

This means that $\sigma = 16, \mu = 200$ .

So his coefficient of variation is

$CV = \frac{16}{200} = 0.08$

Mary's weight has a mean of 125 pounds with a standard deviation of 10 pounds.

This means that $\sigma = 10, \mu = 125$

So her coefficient of variation is

$CV = \frac{10}{125} = 0.08$

They have the same coefficient of variation, so the correct answer is.

Which section of the graph represents the solution of the system of inequalities shown?

3241004551 [841]

Answer:

Step-by-step explanation:

5x+15y ≥ -20

Solve for y

15 y≥ -5x-20

Divide by 15

y ≥ -5x/15 -20/15

y ≥ -1/3 x -4/3

Y is greater than or equal to so shade above and on the line

4x-2y > 6

Solve for y

-2y > -4x+6

y < 2x -3

Shade below the line

The double shaded area is the solution
