Solve: log (2x + 1) = log (x - 1).

no solution

Step-by-step explanation:

For the equation to be equal, the argument of the logarithms on both sides of the equation must be equal.

2 x + 1 = x − 1

Solve for  

x .

x = − 2

Exclude the solutions that do not make  

log ( 2x + 1 ) = log

( x − 1 )  true.

No solution

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
