Answer:
not a function
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
in x<-4 the derivative is positive so the function is increasing.
in x>-4 the derivative is negative so the function is decreasing
increasing in (-infinity,-4)
decreasing in (-4,infinity)
Answer: Let length = 2x + 3
Let width = x
Area = 54 ft2
length × width = Area
x(2x + 3) = 54
2x2 + 3x = 54
2x2 + 3x - 54 = 0
(2x - 9)(x + 6) = 0
x = 9/2 and x = -6
x = 4.5 and x = -6
We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:
width = 4.5 ft
length = 2(4.5) + 3 = 9 + 3 = 12 ft
Step-by-step explanation:
Answer: 1 load of stone weighs 5.75 tons.
Step-by-step explanation: You'll need to divide 23 by 4 leaving you with 5.75. This will help you get a number that is potentially the weight of 1 load. To check to see if this is right, multiply 5.75 by 4 to get 23.
