Keep these rules in mind:

  1. (a + b)² = a² + 2ab + b²
  2. (a - b)² = a² - 2ab + b²
  3. (a + b)(a - b) = a² - b²

Firstly, solve the exponent and multiplication:

4x^2-20x+25-0.5x

Next, combine like terms:

4x^2-20.5x+25

Next, subtract 4x² on both sides:

-20.5x+25

Next, subtract 25 on both sides:

-20.5x

Lastly, divide both sides by -20.5. And since you are dividing by a <u>negative</u>, flip the inequality sign:

x>2

<u>Your answer is x > 2.</u>

Question 6 (1 point) (01.03 LC) What is the value of 5 to the power of 4 over 5 to the power of 6? (1 point) a 1 over 25 b 1 ove
Vlad [161]

Answer:

a 1 over 25

Step-by-step explanation:

Problem Statement:

     What is the value of  \frac{5^{4} }{5 ^{6} } ?

To solve this problem, we must familiarize ourselves with the concept of exponents and rules that guides them.

Exponents are used by scientists to report higher orders of a number.

Such large and often recurring expression is usually made up of a base and an exponent value.

The exponent value is the power of the base;   for example, 4³ has 4 as its base and 3 as the exponent.

Several rules guides solving an exponent, to this problem, the most applicable one is :

                            \frac{x^{a} }{x^{b} }  =  x^{(a-b)}

                           \frac{5^{4} }{5 ^{6} }   =  5^{4-6}  

                                 = 5^{-2}

                                 = \frac{1}{25}                                  

Therefore the solution is 1 over 25

2 points<br> 2. Which of the following graphs represents a FUNCTION? Choose ALL<br> that apply<br> B
inna [77]

Answer:

A, B

Step-by-step explanation:

Not C, D, E, because they show two points with the same x-coordinate but different y-coordinates.

In a function, each x is paired with <u>just one</u> y.

The graph of a function will never have two or more points <u>stacked verticall</u>y.
