The answer is: [C]: " 3 " .
____________________________________
Explanation:
__________________________________
4x - 1 = 2x + 5 ; Solve for "x" ;
__________________________________
Subtract "2x" from each side of the equation; and add "1" to each side of the equation:
___________________________________________________
4x - 1 - 2x + 1 = 2x + 5 - 2x + 1 ;
___________________________________________________
2x = 6 ;
_________________________________
Divide EACH side of the equation by "2" ; to isolate "x" on ONE side of the equation; and to solve for "x" ;
_________________________________
2x / 2 = 6 / 2 ;
_________________________________
x = 3 .

Write the slope-intercept form of the equation of the line 3x - 2y = -16

denis-greek [22]

We will solve for y.
$-3x-16=-2y$

Divide both sides by -2
$y=\frac{3}{2}x + 8$

Slope-intercept form
$y=\frac{3}{2}x + 8$

The mean of the values in a data set is c. If each of the values in the data set were multiplied by 6, what would be the mean of

oksian1 [2.3K]

Answer:

Mean of the data would be 6c

Step-by-step explanation:

Rule to Remember: Whenever each term of the data is multiplied by the same number, the new mean is previous mean multiplied by that number.

In this case, original value of mean was c. Each value of the data is multiplied with 6 so a result the new mean would be 6 times the original mean i.e. 6c

Let us consider that original values in the data set are x, y and z. Their mean would be:

$Mean=\frac{x+y+z}{3}$

If each value of the data is multiplied with 6, the new values would be 6x, 6y and 6z. The mean in this case will be:

$Mean=\frac{6x+6y+6z}{3}\\Mean=\frac{6(x+y+z)}{3}\\Mean=6\times\frac{x+y+z}{3}\\Mean=6c$

We can see from above that the new mean is 6 multiplied to the original mean.

Therefore, the answer to this question is 6c.
