Answer:
x = -2,1,3
Step-by-step explanation:
Given: The curved line represented by the function crosses the x-axis at and y-axis at
To find: value of x for which
Solution:
= gives those values of x for which the curve represented by the given function cuts the x-axis.
According to question, the curve cuts the x-axis at
Write and solve an inequality:
Total(t) = $5.42 + ($1.08/therm)(t) ≤ $87.50.
First, subtract $5.42 from $87.50: then ($1.08/therm)(t) ≤ $82.08
Next, divide both sides by $1.08 per therm:
t ≤ ($82.08) / ($1.08/therm) = 76 therms (maximum). Thus, Rameen's usage could be [0,76] (therms).

Amaya’s because she rounded to the nearest tenth correctly if the number behind the decimal had been 5 or above Katie would be right but because the number is 4 or below you round down therefore 89.1 would be 89 and 9.3 would be 9
