Log 15 (2x − 2) = log 15 (x+9)

notka56 [123]

Answer:

$x=11$

Step-by-step explanation:

Given the equation

$\log_{15}(2x-2)=\log_{15}(x+9)$

Note that

$2x-2>0\\ \\2x>2\\ \\x>1$

and

$x+9>0\\ \\x>-9$

Combined, $x>1$

Solve the equation:

$2x-2= x+9\\ \\2x-x=9+2\\ \\x=11$

Since $11>1,$ this is the solution to the equation.

Given the function f(x) = 5x^2 - x + 20, find f(3)<br> A) -20<br> B)-13<br> C) 62<br> D) 64

Viktor [21]

<h3>Answer: 62 (choice C)</h3>

Work Shown:

f(x) = 5x^2 - x + 20

f(3) = 5(3)^2 - 3 + 20

f(3) = 5(9) - 3 + 20

f(3) = 45 - 3 + 20

f(3) = 42 + 20

f(3) = 62
