Question

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

Answer 1

c

Step-by-step explanation:

Answer 2

c ( x R, x > 5 )

Step-by-step 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.
