2x-8=x+4
Get the x to the other side and the 8 to the opposite
2x-x=4+8
X=12
T(t)=70+110e^(-t/2)
After 4 minutes, t= 4
Substituting in the temperature equation,
T(4 minutes) = 70+110e^(-4/2)=70+110e^(-2) = 84.89 oF
Solving the inequality: we get
Step-by-step explanation:
We need to solve the inequality:
Solving:
Multiply -5 with the terms inside the bracket:
Adding 4f on both sides
Adding 50 on both sides
Divide both sides by 37
So, solving the inequality: we get
