<h2>
Answer: B. 3.99 ⋅ 10^−6</h2>
Step-by-step explanation:
The number that is the smallest has the smallest power of 10.
If we convert the possible answers to ordinary numbers, it will be clearer.
A. 4.4 ⋅ 10^−5 = 0.000044
B. 3.99 ⋅ 10^−6 = 0.00000399
C. 2.6 ⋅ 10^2 = 0.026
D. 1.85 ⋅ 10^3 = 0.00185
Answer:
-6
Step-by-step explanation:
x/3-1= -3
You subtract 3 from 1 to simplify
x/2= -3
Then you multiply 2 to each side
x= -6
Answer:
x = -3 or x = 3
Step-by-step explanation:
Subtract 9 from both sides.
x^2 - 9 = 0
Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.
(x + 3)(x - 3) = 0
Set each factor equal to zero.
x + 3 = 0 or x - 3 = 0
Solve each equation.
x = -3 or x = 3
It pretty much looks like a one to one function. Plot the graph then draw a horizontal line,if the line touches the graph at just one point then it is
We make sample calculations per month, assuming that you visit the gym x times per month.
(1) $39.95 per month
(2) total = $14.95 + $2.95x
If we have the value of x, it is much easier for us to determine the answer by just substituting the value of x and solve. Whichever gives the lower cost will be our answer.
