Please help me!<br><br> 3x + 2 &gt; x - 8 <br><br> (please show work)
pychu [463]

Next time, please include the instructions: "Solve for x:"

Starting with 3x + 2 > x - 8

subtract 2 from both sides, and also subtract x from both sides, obtaining

2x > - 10

Divide both sides by 2: x > -5

What is the answer to a+b=s+r; r
Crank

Answer:      " r  =  a  +  b  -  s "  .

_____________________________________________________

Step-by-step explanation:

_____________________________________________________

Given:  

a + b = s + r ;  Solve for:  "r" ;  that is; rewrite the equation in terms of:  " r " .

_____________________________________________________

Subtract "s" from each side of the equation;  

   to isolate "r" on one side of the equation:

_____________________________________________________

    →      a + b - s  =  s + r - s  ;

    →   to get:

   →       a + b - s  =  r  ;

____________________________________________________

 ↔   " r = a + b - s "  .

____________________________________________________

   →  which is the answer.

Hope this helps!

 Best wishes to you!

Nostrana [21]

Answer:

B. Events A and B are mutually exclusive if A and B have no sample points in common.

Step-by-step explanation:

When two events( call them A and B) are mutually exclusive , it is impossible for them to happen together.

P(A and B) = 0

"The probability of A and B together equals 0 (impossible)"

Hence, the correct answer is B.

B. Events A and B are mutually exclusive if A and B have no sample points in common.
