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:
Observe that if the vector is in W then it satisfies:
This means that each vector in W can be expressed as a linear combination of the vectors
Also we can see that those vectors are linear independent. Then the set
is a basis for W and the dimension of W is 2.
