You have an English language sentence that we need to translate into Mathematics language.
English) (the product of a number and 9), (increased by 4), (is 58) Math) (Number x 4), (+ 7), (= -36) I put in the () to show you what parts go togetherCall the Number N, we can use anything (x,s, ...) but N makes sense (N x 4) + 7 = -36 Can you do the rest? subtract 7 from both sides, divide both sides my 4, there is the answer
Answer:
16. $ 4100
17. y = 10000 - 750x
Step-by-step explanation:
16)
As initial value is $ 5000, and salvage value is $ 500. That means in 5 years value decreased by 5000-500 = 4500 so ,
in 5 year value decreased = 4500
in 1 year value decreased = 4500/5 = 900
so per year 900 $ gets decreased from original price. So equation can be given as
V = 5000 - 900y
where V is value of a vehicle and y is number of year
So after 1 year value would be
V = 5000 - 900 x 1 = 5000 -900 = 4100 $
17)
initial cost of car = $ 10000
per year amount decreases by = $ 750
then equation can be given as
y = 10000 - 750x
where x is number of year and y is cost of car after x year.
The correct answer is 40 which will be letter c
Answer:
3
Step-by-step explanation:
the maximum value of the function y = -2+5sin(pi/12(x-2)) is determined by taking the first derivative of the function. The first derivative is equal ( 5 pi/ 12 )* sin ((pi/12) (x-2)) = 0. x is equal to 4472 through the calculator. Substituting to the original equation, the maximum value is 3.
