Set both inequalities greater than (> )or less than (< ) zero. transform the second inequality so both have the same inequality symbol. apply the transitive property and solve. make sure the leading coefficient is positive. x+7> (−2) and y−5< 9 x+7> (−2)→ y−5< 9→ combined inequality a. 0> y−4 b. 0> y−14 c. x−y> 1 d. x+9> 0 e. x−y> (−23) f. x−5> 0

(e) x−y>(−23)

x+7>(−2) and y−5<9

First isolate x and y

x+7>(−2)→ x > -9

y−5<9→ y < 14

Transform the second inequality to make the < to a > (multiply by -1):

y < 14  → -y > -14  

add both inequalities:

x > -9 and -y > -14

x-y > -9 - 14

x - y > -23

the car was traveling 40 mph before it started skidding. ( 2 points ) 17. was the driver were her brakes working at 75% efficiency or better? ( 2 points ) yes 29.
