if 15bx-20>35 where b is a positive constant, which of the following best describes all possible values of 4-3bx
A) any value less than -7
B) Any value greater than -7
C) Any value less than -11/3b
D) any value greater than -11/3b
+9466 15bx - 20 > 35
We can factor -5 out of 15bx - 20 because -5( -3bx + 4 ) = 15bx - 20
-5( -3bx + 4 ) > 35
Rearrange the terms inside the parenthesees...
-5( 4 - 3bx ) > 35
Divide both sides of the inequality by -5 , a negative number, so swap the sign.
4 - 3bx < -7
