Mathematics
1 answer:
DanielleElmas [232]3 years ago
8 0

Answer:

x = {- 4, 4}

Step-by-step explanation:

factored polynomial is: (x–4)(x+4)

Let (x–4)(x+4) = 0

\therefore \: (x - 4)= 0 \: or \: (x+4) = 0 \\  \therefore \:x = 4 \:  \: or \:  \: x =  - 4 \\  \therefore \:x =  \{ - 4, \:  \: 4 \} \\ are \: the \: required \: roots.

Solve for m 1/C+1/m=1/z
9966 [12]
Answer:  " m = zC / (C − z) " .
___________________________________
Explanation:
_________________________
Given:  1/C + 1/m = 1/z ;  Solve for "m".

Subtract  "1/C" from each side of the equation:
____________________________________
1/C + 1/m − 1/C = 1/z − 1/C  ;

to get:  1/m = 1/z − 1/C ;
____________________________________
Now, multiply the ENTIRE EQUATION (both sides); by "(mzC"); to get ride of the fractions:
_________________

mzC {1/m = 1/z − 1/C} ;

to get:  zC = mC − mz ;

Factor out an "m" on the "right-hand side" of the equation:

zC = m(C − z) ;  Divide EACH side of the equation by "(C − z)" ; to isolate "m" on one side of the equation;

zC / (C − z) = m(C − z) / m ;  to get:   24/8 = 3  24

zC/ (C − z) = m ;   ↔   m = zC/ (C − z) .

The absolute value function, f(x) = |x + 2|, is shown.
Georgia [21]

ANSWER

all real numbers

EXPLANATION

The given absolute value function is

f(x) =  |x + 2|

This function is obtained by shifting the graph of

y =  |x|

to the left by 2 units.

Since the domain of the parent function is all real numbers, the domain of the transformed function is also all real numbers because the shifting the parent function horizontally or vertically does not affect the domain.
