Given: x - 7 > -2. Choose the solution set. a {x | x R, x > -9} b {x | x R, x > -5} c {x | x R, x > 5} d {x | x R, x > 14}

Respuesta :

Answer:

c ( {x | x R, x > 5} )

Explanation:

R is a set of all real numbers.

Given  x - 7 > - 2

Adding 7 to both sides of the inequality,

         x - 7 + 7 > - 2 + 7

         x  > - 2 + 7

         x > 5

Therefore x > 5 gives the set expression x = { 6, 7, 8, 9, ...}, whose elements are all subset of R.

Answer:

c
