Which equation has the solution y=2?
antoniya [11.8K]

Answer:

<h2>3y + 2 = 8</h2>

Step-by-step explanation:

solve A

2y - 3 = 19

2y = 22

y = 11

solve B

3y + 2 = 8

3y = 6

<h2>y = 2</h2>

solve C

4y - 4 = -4

4y = 0

y = 0

solve D

5y + 1 = 10

5y = 9

y = 9/5

A set X consists of all real numbers greater than or equal to 1. Use set-builder notation to define X.
vitfil [10]

Theory:

The standard form of set-builder notation is <span>
 
{ x | “x satisfies a condition” } </span>

This set-builder notation can be read as “the set of all x such that x (satisfies the condition)”.

For example, { x | x > 0 }  is equivalent to “the set of all x such that x is greater than 0”.

 

Solution:

In the problem, there are 2 conditions that must be satisfied:

<span>1st: x must be a real number</span>

In the notation, this is written as “x ε R”. Where ε means that x is “a member of” and R means “Real number”

 

<span>2nd: x is greater than or equal to 1</span>

This is written as “x ≥ 1”

 

Answer:

Combining the 2 conditions into the set-builder notation:

<span>X = { x | x ε R and x ≥ 1 } </span>
