if x = 3
3 > -1, and so you use the x² formula.
Plug in 3 for x
x² = (3)²
Simplify
3² = 3 x 3 = 9
9, or (A), is your answer
hope this helps

The question doesn’t look right but if I’m reading it correctly: You subtract your expenses from your revenue to get your NET income.
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.
Personally I used desmos in algebra it gives you the visual representation x=
(4 x 3) - 8 is your answer.
Product of 4 and 3 translates to 4 x 3
Sum of said product and - 8 translates to 4 x 3 - 8
Because of PEMDAS, we must multiply first. So in order to make sure your expression says this, you must use parentheses.
