ratelena [41]

Answer:

\left|x-3\right|

The graph is also attached.

Step-by-step explanation:

Given the expression

|x-3|\:

Apply absolute rule:

\mathrm{If}\:|u|\:0\:\mathrm{then}\:-a\:

so the expression becomes

-5

x-3>-5\quad \mathrm{and}\quad \:x-3

solving condition 1

x−3<5

Add 3 to both sides

x−3+3<5+3

x<8

solving condition 2

x−3>−5

Add 3 to both sides

x−3+3>−5+3

x>−2

combining the intervals

x>-2\quad \mathrm{and}\quad \:x

Merging overlapping intervals

-2

Therefore,

\left|x-3\right|

The graph is also attached.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!<br><br> Simplify.
astraxan [27]
The answer would be be B
~~~~~~~~~~~~~~~~~~~~~~~
You first factor out 54 and thats 3^2 * 6

(The factor of a # is what you multiply to get the answer)

You then do the same to x^9 and y ^7

After that you should have square root of [3^2 * 6x^8 * xy^6 * y]

When you combine this you will get 3x^4 y^3 sqre root [6xy]

△DEF is shown below.<br><br>Triangle DEF<br><br>What is m∠DEF?​
S_A_V [24]

Answer:

m∠DEF = 50

Step-by-step explanation:

∠DEG = ∠GEF

3y + 4 = 5y - 10

subtract 4 from both sides

3y = 5y - 14

subtract 5y from both sides

-2y = -14

divide by -2

y = 7

Add 7 into the equations:

3y + 4 + 5y - 10

3(7) + 4 + 5(7) - 10

21 + 4 + 35 - 10

25 + 25

50
