Question

1) logo,1(10x - 7)=-1;​

Answer 1

Ответ:

$1,7$

Объяснение:

$log_{0,1}(10x-7)=-1\\\\10x-7>0\\10x>7\\x>0,7\\\\log_{0,1}(10x-7)=-1\\10x-7=(0,1)^{-1}\\10x-7=10\\10x=17\\x=1,7\;\in(0,7;+\infty)\\\\x=1,7$

Answer 2

It looks like you've provided an equation with a variable (x) in it. To solve for x, we can follow these steps:

$1(10x - 7) = -1$

First, distribute the 1 on the left side of the equation:

$10x - 7 = -1$

Next, isolate the term with x by adding 7 to both sides of the equation:

$10x = 6$

Finally, solve for x by dividing both sides by 10:

$x = \frac{6}{10} = \frac{3}{5}$

So, the solution to the equation is $x = \frac{3}{5}$.
