Answer:

f(- 5) = 25

Step-by-step explanation:

To evaluate f(- 5) , substitute x = - 5 into f(x) , that is

f(- 5) = - (- 5)² - 10(- 5) = - 25 + 50 = 25

Answer:

A. \frac{1}{5} log_{3}x +log_{3}y

Step-by-step explanation:

We have the expression

log_{3} (\sqrt[5]{x} *y)

As these two values are being multiplied, we can separate the two and the sum of them will be equal to the multiplied version

log_{3}\sqrt[5]{x} +log_{3}y

The \sqrt[5]{x} can be rewritten as x^{\frac{1}{5} }. This allows us to use the exponent rule. This means that it can be written as

\frac{1}{5} log_{3}x +log_{3}y

What is StartFraction one-half EndFraction x is less than or equal to 18.x ≤ 18
Eduardwww [97]

Answer:

x\leq 36

The solution for x is all real numbers less that or equal to 36.

Step-by-step explanation:

Given expression:

\frac{1}{2}x\leq18

To find the solution for x

Solution:

In order to solve for x , we will make sure to isolate the unknown variable x on left side alone by doing math operations on both sides of the inequality.

We have:

\frac{1}{2}x\leq18

Multiplying both sides by 2.

2.\frac{1}{2}x\leq18\times 2

The 2 on left side will cancel each other leaving x alone.

Thus, we have:

x\leq 36

Thus, solution for x is all real numbers less that or equal to 36.
