Equality Properties

Algebra I

Standard Form: ax² + bx + c = 0
Quadratic Formula: $\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Algebra II

Imaginary Roots: √-1 = i

Step-by-step explanation:

Step 1: Define

6x² = 2x - 1

Step 2: Rewrite

Subtract 2x on both sides: 6x² - 2x = -1
Add 1 to both sides: 6x² - 2x + 1 = 0

Step 3: Identify Variables

a = 6

b = -2

c = 1

Step 4: Solve for x

Substitute [QF]: $\displaystyle x=\frac{2\pm\sqrt{(-2)^2-4(6)(1)} }{2(6)}$
Exponents: $\displaystyle x=\frac{2\pm\sqrt{4-4(6)(1)} }{2(6)}$
Multiplication: $\displaystyle x=\frac{2\pm\sqrt{4-24} }{12}$
(Square Root) Subtract: $\displaystyle x=\frac{2\pm\sqrt{-20} }{12}$
Factor: $\displaystyle x=\frac{2\pm \sqrt{-1} \sqrt{20} }{12}$
Simplify: $\displaystyle x=\frac{2\pm 2i\sqrt{5} }{12}$
Factor GCF: $\displaystyle x=\frac{2(1\pm i\sqrt{5} )}{12}$
Simplify: $\displaystyle x=\frac{1\pm i\sqrt{5}}{6}$

Devin has a new cell phone that holds 1.5 gigabytes of memory

stepan [7]

He has enough memory space to download a song that will use 0.12 gigabytes of memory

The memory capacity of new cell phone = 1.5 gigabytes

The memory capacity that already used = 1.35 gigabytes

The remaining space = The memory capacity of new cell phone - The memory capacity that already used

Substitute the values in the equation

Here we have to use the subtraction

The remaining space = 1.5 - 1.35

Subtract the terms

= 0.15 gigabytes

The size of the song = 0.12 gigabytes

We know 0.15 > 0.12

Hence, he has enough memory space to download a song that will use 0.12 gigabytes of memory

The complete question is

Devin has a new cell phone that holds 1.5 gigabytes if memory for music. He has already used 1.35 gigabytes of the memory. Will he have enough space to download a song that will use 0.12 gigabyte of memory? Explain.
