Math <br><br><br> help pls!!<br><br> solve for x and y
Elan Coil [88]

Answer:

x = 7 ,  y= - 6

Step-by-step explanation:

4x = -2 - 5y ___(1)

4x= 10 - 3y ___(2)

so, now by simultaneous equations,

10 - 3y = - 2 - 5y

2y = -12

y = -6

if y = -6

then, 4x= 10 -3(-6)

4x =28

x = 7

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>
