Solve the inequality 2x + 8 < 5x − 4.

Jobisdone [24]

The answer should be X>4

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

2*x+8-(5*x-4)<0

Step by step solution :

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

-3x + 12 = -3 • (x - 4)

Equation at the end of step 1 :

Step 2 :

2.1 Divide both sides by -3

Remember to flip the inequality sign:

Solve Basic Inequality :

2.2 Add 4 to both sides

x > 4

What is the square root of -1

Romashka [77]

Answer:

Step-by-step explanation:

Now, before you think I'm just stealing points, let me explain. The square root of a number is the number that, if you multiply it by itself, it equals that number. The square root of 4 is 2, because 2 * 2 = 4.

Also, a negative number times another negative number, is a positive number. -2 * -2 = 4

With both of those true, then what number could be multiplied by itself to equal a negative number? i.

i is a weird number that I don't really know how to explain all that well. I am sorry, but that is all that I can give you. i is very complex and has various different equivalents, and different meanings, but i is equal to $\sqrt{-1}$ .
