Which of the following is equal to the rational expression when x ≠ -4 or 16?
stepan [7]

Answer:

C

Step-by-step explanation:

Given

\frac{x^2-16}{(x-16)(x+4)}

The numerator is a difference of squares

x² - 16 = (x - 4)(x + 4)

= \frac{(x-4)(x+4)}{(x-16)(x+4) } ← cancel the common factor (x + 4) on numerator/ denominator

= \frac{x-4}{x-16} → C

If we changed the –0.14 to a 2 in the equation, what would happen to the graph?
MatroZZZ [7]

If -0.14 is changed to 2, the graph would become a positive graph, or it would be steeper, because it has a positive slope

The equation of the graph is given as:

y = -0.14x + 3

The above equation is a linear equation, which is represented as:

y =mx + c

Where m represents the slope of the linear equation.

By comparison, we have:

m = -0.14

i.e. the slope of the equation y = -0.14x + 3 is -0.14

When -0.14 is replaced with 2, the equation becomes

y = 2x + 3

And the slope of the new equation y = 2x + 3 is

m =2

2 is greater than -0.14, and 2 is positive.

This means that the graph would become a positive graph, or it would be steeper, because it has a positive slope

EASY WORK!!! Please look at the picture and yes it’s easy for other people but not for me .
Vesnalui [34]

Answer:

#8 --->      1/4  2/5  1/2  3/5  

#9 --->      6 3/8    6 1/2   6 3/4   6 5/6

#10 --->    1.75 feet is the longest

the other lengths are 1.58 ft. and 1.67 ft.

Step-by-step explanation:

good luck!

it's easy if you turn them into decimals.

to do that, you just divide the numerator (top number) by the denominator (bottom number).

e.i.   1/4= .25  (25%)

       1/2= .5   (50%)

       3/5= .6    (60%)
