Answer:

10.-8/-2 can't represent calculating a mean change in score because a mean change in score is counted by adding up the scores & then dividing it by the number of the scores. As a number of scores can never be negative, so -8 can't be divided by -2 . So, -8/-2 can't represent this.

6. a) Andrea's mean weekly change will be negative. Because after adding up her weekly changes, we'll find a negative number. & as the number of weeks is positive, then the mean will be a negative number .

b)the division equation is: -15/5

So, her mean weekly change is -3

What is the x in this equation 14x−8=4

Aleksandr-060686 [28]

Answer:

x = 6 / 7

Step-by-step explanation:

Let's solve your equation step-by-step.

14 x − 8 = 4

Step 1: Add 8 to both sides.

14x − 8 + 8 = 4 + 8

14x = 12

Step 2: Divide both sides by 14.

14 x / 14 = 12 / 14

x = 6 / 7

Which ordered pair would be a solution on the graph of the following system of inequalities: y is greater than or equal to negat

daser333 [38]

Ordered pair is $( x, y)= ( \frac{20}{17} , \frac{-126}{17} )$

Step-by-step explanation:

We have the following inequalities:

$y \geq \frac{-x}{2} - 8$ and $y < 8x +2$ . In order to find ordered pair would be a solution on the graph .Let's solve both inequalities , and will take common solution from both of them !

$y = \frac{-x}{2} - 8 \\$ and , $y = 8x +2$ which implies:

⇒ $8x + 2 = \frac{-x}{2} - 8$

⇒ $\frac{17x}{2} = - 10$

⇒ $x = \frac{-20}{17}$

putting value of x in both inequalities we get,

$y \geq \frac{-x}{2} - 8$ and $y < 8x +2$

$y \geq \frac{-(\frac{-20}{17} )}{2} - 8$ and $y < 8.(\frac{-20}{17}) + 2$

$y \geq \frac{-126}{17}$ and $y < \frac{-126}{17}$

Hence at x = $\frac{-20}{17}$ and y = $\frac{-126}{17}$ above inequalities are satisfied. ∴ Ordered pair is $( x, y)= ( \frac{20}{17} , \frac{-126}{17} )$
