Answer:

Step-by-step explanation:

$\overline x =\dfrac{-3\cdot4+(-2)\cdot2+3\cdot1+4\cdot1+6\cdot4+8\cdot7}{4+2+1+1+4+7}\\\\\\\overline x =\dfrac{-12-4+3+4+24+56}{19}\\\\\\\overline x =\dfrac{71}{19}=3.7368421....\approx3.74$

Through:(4,4),parallel to y=-6x +5

ad-work [718]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

In this case we have the following equation of the line:

$y = -6x + 5$

Where:

$m = -6$

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will have an equation of the form:

$y = -6x + b$

Substitute the given point $(x, y) :( 4,4)$ to find "b":

$4 = -6 (4) + b\\4 = -24 + b\\4 + 24 = b\\b = 28$

Finally, the equation of the requested line is:

$y = -6x + 28$

Answer:

$y = -6x + 28$

On a cold winter day the temperature was -1 below zero. At night the temperature be dropped 4. What was the final temperature

Savatey [412]

Answer:

-1 + -4 = -5 below zero....If the temperature is -1 + 4 the temperature would be 3 degrees (-1+4=3)

Step-by-step explanation:

If the temperature is -1 + -4 = -5 below zero (adding two negatives equal a negative number).

If the temperate is -1 + 4 = 3 (+4-1=3) The number is positive because it is larger than the negative number.
