Say the slow hose flows x
The fast hose flows 4x
5x = 24
x = 4.8

The equation
ra1l [238]
<h2>Explanation:</h2>

Let's use a trial and improvement method to find this solution.

Step 1. Let's choose x = 8.5

Substituting into the equation:

(8.5)^2+ 3(8.5) - 94=0? \\ \\ 72.25+25.5-94=0? \\ \\ 3.75\neq 0

Step 2. Let's choose x = 8.4

Substituting into the equation:

(8.4)^2+ 3(8.4) - 94=0? \\ \\ 70.56+25.2-94=0? \\ \\ 1.76\neq 0

Step 3. Let's choose x = 8.3

Substituting into the equation:

(8.3)^2+ 3(8.3) - 94=0? \\ \\ 68.89+24.9-94=0? \\ \\ -0.21\neq 0

Since the sign of the equation changes from positive to negative when evaluating from 8.4 to 8.3, then x = 8.3 seems to be a reasonable value. Finally, the solution to 1 decimal place is:

x=8.3

Which equation has 1 solution?<br><br> IwI = -2<br> IwI = -1<br> IwI = 0<br> IwI = - 1
vovangra [49]
Absolute value is alwas positive
so all of them excet the 3rd one are false

|w|=0 has 1 solution


if the last one was |w|=1 then ther would be 2 solutions, -1 and 1


answer is |w|=0

Can someone give 2 examples of a logarithmic equation with infinite solutions?
Vika [28.1K]

Assuming what is meant by "infinite solutions" are infinite number of solutions of a logarithmic equation.  

\frac{1}{2}\log x^2 - \log \sqrt{x} - \log \sqrt{x} = 0

and

\frac{1}{2}x-2\ln e^x=-\frac{3}{2}x
