5. suppose you went on vacation but forgot your smart phone
charging cable. your phone battery died after two full days
(48 hours) of use. this situation is modeled by the equation
f(h) = 48, where h is the hours of cell phone use and
f(h)is the percentage of battery life left.
what is the upper bound of the parameter h?
hrs
what is the lower bound of the parameter h? •
hrs

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5
