Solve the inequalities -150x ≥ − 2,400 and -336 ≥ − 21y.
2 answers:
Ok so easy peasy
remember that when divide or multiply by negative, reverse the inequality symbol example
2>3 times -1=
-2<-3 so
-150x<u>></u>-2400
divide both sides by -150
flip sign
<u />x<u><</u>16
-336<u>></u>-21y
divide both sides by -21
flip sign
16<u><</u>y
they seem to have the same solution
x=y<u>></u>16
-150x>_ -2400
Divide both sides by -150
-150x/-150>_ -2400/-150
x<_ 16
-336>_ -21y
Flip the equation
-21y<_-336
Divide both sides by -21
-21y/-21<_ -336/-21
y>_ 16
I hope that's help !
