Solve the equation by using the basic properties of logarithms. ln(x+4)=-1

amid [387]

Write both sides as powers of $e$ :

$\ln(x+4)=-1\implies e^{\ln(x+4)}=e^{-1}\implies x+4=e^{-1}$

since $b^{\log_ba}=a$ . Then

$x=e^{-1}-4\approx-3.63$

7x-10+2x=39+2x what is the answer

stich3 [128]

Answer:

X=7

Step-by-step explanation:

STEP 1: Simplify both sides of the equation

7x + -10 + 2x =39 + 2x

(7x + 2x) + (-10) = 2x + 39 (combine like terms)

9x -10 = 2x + 39

step 2: Subtract 2x from both sides

9x -10 - 2x = 2x + 39 - 2x

7x - 10 =39

Step 3: Add 10 to both sides.

7x - 10 + 10 = 39 + 10

7x = 49

Step 4: Divide both sides by 7.

7x/ 7 = 49/7 x=7

hope this helps!!

Neither

Step-by-step explanation:

This questions only states

$y = 11.1.07\%$

This is not a fucntion because there is no variable.

This is not a valid statement, because 11.1.07% is non-sensical.
