how to find the absolute value of the ff:?

Question

-15
(2,-7)
-(-3-9)
pls. help me bec. i'm so confused in finding the absolute value bec. there is no vinculum.

and also this:
-5
-(-7)
x-3
2x-3
how will i find the reciprocal?

Answer 1

Well Mency
value of a number is always a positive number (or zero). We specify the absolute value of a number n by writing n in between two vertical bars: |n|
Examples:
|6| = 6
|-0.004| = 0.004
|0| = 0
now part One;
-15 = | -15| = +15
(2,-7) = (|2| , |-7| ) = (+2 , +7)
-(-3-9) = -( -12) = +12 = |12| = 12

Part Two;
{ for this sport of question , you just need to make a fraction that the numerator is 1, i just give you an example ;
if a is a number so the reciprocal is 1/a . but sometime you have to find the reciprocal of a fraction like 1/x so the result is ;
1/(1/x) = (1/1) / (1/x) = (x*1) / (1*1) = x /1 = x}

-5 = -(1/5)
-(-7) = +1/7
x-3 =1/(x-3)
2x-3 = 1/(2x-3)

Good Luck sweet heart.

Answer 2

the get the reciprocal you but 1 over those numbers like -1/5

1/7 1/x-3 1/2x-3

and the absolute value of all those numbers shoud be positive

15 5 12

Answer 3

if the number is zero absolute is 0 if it is positive aboslute is same and if it is -ve abosulte is -te of it

for - 15 it is 15
for (2-7) that is -5 it is 5
for-(-3-9) or 12 it is 12
for -5 again 5
for -(-7) that is 7 is 7
for x-3 it is tircky situation
it is x-3 if x-3>= 0 or x>=3
and 3-x if it is <0 if x-3 <0 or x <3
for 2x-3 it is 2x-3 when x>=3/2 else 3-2x

finding reciprocal is easy that is for x it is 1/x

if it is (x-3) then 1/(x-3)
