Answer:
x =
Step-by-step explanation:
Given
x + =
Multiply through by 80 ( the LCM of 20 and 16 ) to clear the fractions
80x + 36 = 45 ( subtract 36 from both sides )
80x = 9 ( divide both sides by 80 )
x =
"Rationalizing the denominator" of a number is exactly what its title implies: turning its denominator into a rational number.
For an example, let's take the fraction 1/√2. We call √2 <em>irrational</em> because it cannot be expressed as a <em>ratio </em>of two integers. Oftentimes when we have irrational numbers like √2 in the denominator, it helps to perform a little bit of algebraic manipulation on them to make the denominator rational. Here's where that "form of 1" comes in. Remember that, as a rational number, 1 can be expressed as n/n, where n is any number. We can use this fact to rationalize the denominator of 1/√2 <em />by multiplying it by √2/√2, which is equivalent to 1.
When we multiply the two together, we get:
Crucially, multiplying by 1 in the form of √2/√2 <em>keeps the fraction's value the same</em>, since 1 times any number just equals that same number. If we weren't multiplying but some form of 1, we'd change the number entirely, making the whole attempt at rationalizing the denominator pointless.
Answer:
See below
Step-by-step explanation:
There are two ways to graph an equation.
<u>1st Way:</u>
We can use a graphing calculator. (See the attached file)
<u>2nd Way:</u>
We can take the values of x as 0, 1 , 2 (Or anything).
Then, We have to put the values of x in the equation to get the value of y accordingly.
According to these values, Plot the graph.
Also,
Slope = 5 / 6
y-intercept = 1

A technique of expressing an equation in the most efficient form possible while altering the quality of the underlying statement is known an algebraic equation.
<h3>Simplifying the given expression:</h3>
⇒ (- 20 - 3i) - (- 22 - 1i)
⇒ (- 20 - 3i + 22 + 1i)
⇒ (2 - 2i)
Therefore the simplification of the given expression is "(2 - 2i)"
