Lnx=-3
scZoUnD [109]

Answer:

because It's rounded to the nearest hundred place

Step-by-step explanation:

Given equation:

  • \ln(x )  =  - 3

recall that,

\ln(a )  =  b \iff  {e}^{b}  = a

remember, <em>In </em>is natural logarithm which is actually nothing but common logarithm with the base euler's number (<em>e)</em><em> </em>. anyway rewriting lnx=-3 yields:

\ln( x )  =   - 3\\  \iff  {e}^{ - 3}   =  \frac{1}{ {e}^{3} }

1/e³ is approximately 0.0497870684..... , rounding it to the nearest hundred place would be 0.05 which is the same answer as your textbook .

plz help doing test rn i need it

Answer:

|answer|  \\ 1)0=0 \\ 2)0=28

3)The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.
