Equivalent to<br> what is a expression equivalent to log18 – log(p + 2)?

Pie

Log(18) - log(p+2)
because base of both logarithms is 10 that means we can merge them into one logarithm

the rule is as fallows:
log(b) - log(c) = log (b/c)
log(b) + log(c) = log(b*c)

since sign between our 2 logarithms is - that means that we need to divide

answer is:
log(18/(p+2))

Which monomial is a perfect cube?

neonofarm [45]

Answer:

Option (a) is correct.

$1x^3$ is a perfect cube.

Step-by-step explanation:

Given : Some Monomial

We have to choose out of given monomial that is a perfect cube.

Perfect cubes are numbers that can be written as $(ab)^3$

So, consider $1x^3$ , we know 1 can be written as $1^3$

Thus, $1x^3$ can be written as $1^3x^3=(1x)^3$

Thus, Option (a) is correct.

For this case we have that by definition, a function is of the form:

$y = f (x)$

So, we have the following system of equations:

$y = -6x + 2\\y = -2x + 4$

Equating the equations we have:

$-6x + 2 = -2x + 4$

Adding 2x to both sides of the equation:

$-6x + 2x + 2 = 4\\-4x + 2 = 4$

Subtracting 2 from both sides of the equation:

$-4x = 4-2\\-4x = 2$

Dividing between -4 on both sides of the equation:

$x = \frac {2} {- 4}\\x = - \frac {1} {2}$

Thus, the value of the variable "x" is -0.5.

Answer:

-0.5
