Answer:
Step-by-step explanation:
There's no "solving" to be done because its an expression, but im assuming the question wants you to factor.
First, factor out a b^2
Factor the trinomial. What two numbers multiply to equal -10 but add to equal -3? They are -5 and +2
The flat fee that the store charges is $14 and the cost for 7 hours is $56
A linear equation is on the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
let f for the total rental cost of a vacuum cleaner for x hours
Using the points (1, 20) and (3, 32) from the table:
The flat fee that the store charges is $14
The reasonable domain is 1 ≤ x ≤ 12
The cost for 7 hours is:
f(7) = 6(7) + 14 = 46

Answer: $3,664.21
Formula:
- P = principle/original amount = $3000
- r = rate of interest = 4% = 0.04
- t = time period (in years) = 5
- A = the new amount
- e = Euler's number ≈ 2.718...
Substitute in the values:
<u>Approximately $3,664.21</u>
