Math help? please?

Answer 1

Here you go :) The correct answer for #2 is {x | x R, x > -5} and #3 is {x | x R, x < -2}. #1 in the photo is correct.

Answer 2

Answer:

$x-5>-2$;Option third is correct

$x - 5 > -10.$;Option two is correct

$5 > x + 7$;Option two is correct

Explanation:

In case $x-5>-2$ simply the expression we will get

$x>-2+5=x>3$

Hence, option third that is $(x| x R,x>3)$

In case $x - 5 > -10.$ simplify the expression we will get

$x>-10+5\\x>-5$

Hence, Option two is correct

$(x| x R,x>-5)$

In case $5 > x + 7$  simplify the expression we will get

$5>x+7\\5-7>x\\-2>x\\x$

Hence, Option two is correct
