Write and solve a real world problem that can be represented by the expression (-3)(5)+10

Problem:

The initial temperature of a room is equal to 10 degrees Celsius. The temperature of the room decreases by 3 degrees per day. Find the temperature of the room in 5 days.

Solution:

The temperature of the room in five days is given by the expression:

Resolving the expression we have:

Therefore, the temperature of the room for day number 5 is equal to -5 degrees Celsius.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
