If you go from point (-1, -3) to point (4, 4), you can find the slope of the line using the slope formula.  m= \frac{4-(-3)}{4-(-1)}= \frac{7}{5}.  So our slope is 7/5.  The line goes through the y axis at -3/2, so putting that together we get an equation for the line that is  y= \frac{7}{5}x- \frac{3}{2},  choice D from above.

Find the derivative of f(x) = negative 9 divided by x at x = -4. (6 points) 4 divided by 9 16 divided by 9 9 divided by 16 9 div
Len [333]

Answer:

9/16

Step-by-step explanation:

f(x)=-\frac{9}{x}

f(x)=-9x^{-1}

Derivative rule:

f(x)=x^{n} \\

\frac{df}{dx}=nx^{n-1}

Here, n=-1, so

\frac{df}{dx}=(-9)(-1)x^{-2} =\frac{9}{x^{2} }

Evaluating this at x=-4 gives 9/16

BRAINLIEST!!PLEASE HELP ME!!
pishuonlain [190]

Answer:


Step-by-step explanation:

The truck's fuel consumption is:

660 miles

---------------- = 7.33 miles per gallon.

90 gallons

Draw a set of coordinate axes, with # of gallons on the horiz. axis and distance traveled on the vertical axis.  Place a black dot at (0,0).  Starting at (0,0), draw in scale divisions that can accommodate 0-100 gallons.  Mark scale divisions on the vertical axis such that the maximum distance traveled is 800 miles.  Now draw a vertical line through 90 gallons and a horizontal line through 660 miles.  Draw a black dot where these two lines intersect.  Now draw a straight line through (0,0) and (90,660).  These two points are your intercepts, horiz. first and vert. second.

The domain is the set of numbers on the horiz. axis for which you have a graph (meaning that your function is defined).  Here your domain is

[0,90] gallons.  No function is defined for less than 0 gallons or more than 90 gallons.

The origin represents no fuel yet consumed and no distance yet traveled.

The roots of the equation x2 - 14x + 48 = 0) are
MrRissso [65]

Answer:

{x}^{2}  - 14x + 48 = 0 \\  {x}^{2}  - 6x -8 x + 48 = 0 \\ x(x - 6) - 8(x - 6) = 0 \\ (x - 6)(x - 8) = 0 \\ \boxed{ x = 6\: and \: 8}

  • 4) <em><u>6 and 8</u></em> is the right answer.
