S(t) = -105t + 945 to determine the salvage value, S(t), in dollars, of a table saw t years after its purchase. How long will it take the saw to depreciate completely? A. 11 years B. 8 years C. 7 years D. 9 years

D

Step-by-step explanation:

When something depreciates completely, it will have a total value of 0 dollars. Therefore, set the equation to zero and solve for t to find the years.

Therefore, the table saw will completely depreciate after 9 years.

Step-by-step explanation:

For the value to depreciate completely, the amount has to be equal to 0 dollars.

Set S(t) to 0.

Solve for the time t.

Subtract 945 from both sides.

Divide both sides by -105.

It will take 9 years for the saw to depreciate completely.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

step-by-step explanation:

i think you should think about the question and not look online.
