Answer 2

Answer: $\log_2(5x - 2) - \log_2 x - \log_2(x - 1) = 2$
$\log_2 ( (5x - 2)/(x(x-1)) ) = 2$
$\log_2 ( (5x - 2)/(x(x-1)) ) = \log_2 4$
$(5x - 2)/(x(x-1)) = 4$
$5x - 2 = 4x(x - 1)$
$5x - 2 = 4x^2 - 4x$
$0 = 4x^2 - 9x + 2$
$0 = (4x - 1)(x - 2)$
$\implies x = 2 \text{ or } x = (1)/(4)$

By putting one quarter into the equation we can see that it cannot work in any way involving real numbers as $\log_2 ( (1)/(4) - 1)$ would be log of a negative number, so x = 2.

An algebraic expression that can be used to represent the new y-coordinate after a translation of four yards south is y-4.

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Let's assume that 1 unit represents 1 mile.

Given that the present coordinate of the point is y. Now, if the point is moved towards the south, then the point will be shifted to 4 units sown. Therefore, we can write an algebraic expression to represent the new y-coordinate after a translation of four yards south as,

New-coordinate = y - 4

Hence, an algebraic expression that can be used to represent the new y-coordinate after a translation of four yards south is y-4.

Use the table below to answer the following question.2. Do the values in the table represent a linear function? If so, what is the function rule?
(1 point)
The values do not show a linear function.
Yes, the values show a linear function: y = x + 4.
Yes, the values show a linear function: y = 2x + 2.
Yes, the values show a linear function: y = 2x.

Answers

The values in the table do represent a linear function.

Y = 2X

Plug in values from the table

108 is 36% of what number? Write and solve a proportion to solve the problem

Answers

Let the number = x

Then, it would be: (x*36)/100 = 108

x*36 = 10800

x = 10800/36

x = 300

108 is 36 percent of the number 300.

Use a proportion to proceed to find the number.

A proportion is an equation that shows two ratios are equivalent.
In this case, we want to find the number that 108 is 36% of.

Write this proportion as:

108/x = 36/100

Here,

x represents the unknown number that we want to find.

Simplify this proportion by cross-multiplying:

(108)( 100) = 36x

Simplifying further, we get:

x = (10800)/36

x = 300

Therefore, 108 is 36% of 300.

Hence, the required number is 300.
