Mathematics
1 answer:
iragen [17]4 years ago
4 0

Answer:

\left\{x\in \mathbb {Z}\ : \ x \le 0 \right\}

Step-by-step explanation:

Set-Builder Notation: A shorthand used to describe sets, often sets with an infinite number of elements.

The set {...,-3, -2, -1, 0} is the set of all negative integers and 0, so you can use such set-builder notation:

\left\{x\in \mathbb {Z}\ : \ x \le 0 \right\}

<u>Note:</u> Here \mathbb{Z} represents the set of all integers.

Could someone please explain "Variables on Both Sides of a Complex Equation"? ​
vodka [1.7K]

Answer:

Step-by-step explanation:

Let's start with an equation like 2x+4=10. We have to isolate x to get an answer. We go for the number without the variable first.

2x+4=10

  Subtract 4 from both sides.

2x+4-4=10-4

2x=6

Divide by 2.

2/2=6/2

x=3

There you go!

Find the value of a.<br> 4x + ax = - 2x(2x + 1)
Karo-lina-s [1.5K]

Answer:

a = -2(2x+1)-4

Step-by-step explanation:

1. Factor out the common term x.

x(4+a)= -2x(2x+1)

2. Cancel x on both sides.

4+a= -2(2x+1)

3. Subtract 4 from both sides.

a= -2(2x+1)-4
