The answer is .07 to this question
Answer:
domain is all real number
Answer:
2x + 4
Step-by-step explanation:
Let R = Ralph's age
and x = Sarah's age
Then Ralph's age in 4 years = R + 4
and Sarah's age in four years = x + 4
Thus, R + 4 = 2(x + 4)
Distribute the 2 R + 4 = 2x + 8
Subtract 4 from each side R = 2x + 4
Ralph's age is 2x + 4.
> Factor the expression for the revenue
We are given that the revenue is the product of price and
number of units sold = x p. Given the equation of revenue we factor it:
R = 800 x – 0.25 x^2
Take out x from the equation:
R = x (800 – 0.25 x)
We see that this is now in the form x p
> Determine an expression for the price in terms of x
From the factored equation we can say that the price in
terms of x is:
<span>p = 800 – 0.25 x</span>
