Given the following functions f(x) and g(x), solve f over g(−4) and select the correct answer below:

marishachu [46]

$\left(\dfrac{f}{g}\right)(x)=\dfrac{f(x)}{g(x)}\\\\f(x)=4x-4;\ g(x)=x-1\\\\f(-4)=4\cdot(-4)-4=-16-4=-20\\\\g(-4)=-4-1=-5\\\\\left(\dfrac{f}{g}\right)(x)=\dfrac{-20}{-4}=4$

The vertices of quadrilateral ABCD are A(3,0), B(4,3), C(7,3), D(6,0).

Anna007 [38]

(a) If AB = CD and AB || CD then ABCD is a parallelogram.

$A(3,0), B(4,3), C(7,3), D(6,0)
\\d(A,B)= \sqrt{(4-3)^2+(3-0)^2} = \sqrt{10}
\\d(C,D)= \sqrt{(6-7)^2+(0-3)^2} = \sqrt{10}
\\AB=CD
\\
\\m_{AB}= \frac{3-0}{4-3} =
\\
\\m_{CD}= \frac{0-3}{6-7}=3
\\
\\m_{AB}=m_{CD}\Rightarrow AB||CD$

(b) If AB ≠ BC then ABCD is not a rhombus.

$B(4,3), C(7,3)
\\d(B,C)= \sqrt{(7-4)^2+(3-3)^2}=3
\\BC \neq AB$

Joshua, an editor for the Winston Salem Gazette, edits 1⁄6 of a page in 3 minutes. How long would it take him to edit 3 pages?

quester [9]

Answer:

54

Step-by-step explanation:

If we know that Josh edits at a rate of 1/6 of a page in three minutes... then using the Unit rule... we can determine that he edits 1 whole page 6 times longer than that. By doing that... we find that Josh edits 1 page in 18 minutes. From there... we multiply the time at which it takes him to edit one page (18 minutes) by 3 (pages) to get our answer.

18 x 3 = 54
