Answer:

x = 3/10

Step-by-step explanation:

−1/2 − (−4/5) = x

First, switch sides.

x = −1/2 − (−4/5)

You are subtracting a negative number. Subtracting a negative number means add a positive number.

x = -1/2 + 4/5

Now you are adding two fractions, so you need a common denominator. The LCD of 2 and 5 is 10.

x = -5/10 + 8/10

x = 3/10

Answer:

your answer might be 1.1

Step-by-step explanation:

You see you have to divide it so it will be -1 divided by 2-(- 4 divided by5)=x so if we do x - those all our answer will be 1.1 your welcome I hope that helps

Answer:

$\boxed{18}$

Step-by-step explanation:

One of the rules of logarithms is ...

log(a^b) = b·log(a)

So ...

$6\log_5{x^3}=6(3\log_5{x})=\bf{18}\log_5{x}$

The local minima of $f\left(x\right)=\ \frac{\left(2x+3\right)^2\left(x\ -2\right)^5}{x^3\left(x-5\right)^2}$ are (x, f(x)) = (-1.5, 0) and (7.980, 609.174)

<h3>How to determine the local minima?</h3>

The function is given as:

$f\left(x\right)=\ \frac{\left(2x+3\right)^2\left(x\ -2\right)^5}{x^3\left(x-5\right)^2}$

See attachment for the graph of the function f(x)

From the attached graph, we have the following minima:

Minimum = (-1.5, 0)

Minimum = (7.980, 609.174)

The above means that, the local minima are

(x, f(x)) = (-1.5, 0) and (7.980, 609.174)
