Answer:
The answer is 1.
Step-by-step explanation:
The number is usually in front of the variable, if there is no number, it is a 1.
Start with the general formula. The key word is difference. So the general formula is
D(x) = W(x) - R(x) Now substitute in the values for W(x) and R(x)
D(x) = 0.002x^3 - 0.01x^2 - (x^2 - 4x + 13) Be very careful about the sign in front of the brackets.
D(x) = 0.002x^3 - 0.01x^2 - x^2 + 4x - 13 Do you see what that minus sign did? It affected all 3 terms.
D(x) = 0.002x^3 - 1.01x^2 + 4x - 13 <em>Note: -0.01 - 1x^2 = - 1.01 x^2</em>
That gives you a clear cut answer
C<<<<< answer.
That sign is the worst part of the question. Make sure you understand what it did.
Plug the x value into the x value for your questions.

9.) -2
2/3 is the answer.
<span>1/3 is equal to 33.33333333% </span>
<span>so 2/3 is equal to 66.6666666%</span>
