Answer:
Hey its D I think.
Step-by-step explanation:
1. The way I think of it is putting a negative number in front as a x value.
I chose -1,-2 and -3.
-1-5<0 -2-5<0 -3-5<0
-6<0 -7<0 -8<0
The reason why it satisfies because negative number are all real numbers less than one. Hope that helps:)
Answer:
Step-by-step explanation:
(a) Option B cost less at 120 miles driven
The cost difference at 120 miles between option A and option B is $15
(b) Option A and B cost the same at driving 60 miles.
Option B would cost more if you drive less than 60 miles.
PEMDAS: distribute the negative to (-2-5x) so it becomes (2+5x)+(-2)=18
Add 2 to both sides: 2+5x=20
Subtract 2: 5x=18
Divide 5: x= 18/5
