The correct answer to this question is letter "A. complex." A number written in the form a + bi is called a complex number. The "i" part is the imaginary part of that expression, which is complex. Imaginary numbers are complex and it's hard to evaluate, sometimes.
<span>Given that for every $1 increase in the price of the t-shirts, they will sell 20 less shirts. The revenue function R(x) is giiven by R(x) = (400 - 20x)(10 + x) = 4000 + 200x - 20x^2. Therefore, the revenue function representing the revenue Mrs Bell's class earns from selling Hobbs Middle Jaquar t-shirts is given by R(x) = 4000 + 200x - 20x^2 where x represent the $1 price increases and revenue is equal to the number of t-shirts sold times the cost of each shirt.</span>
Answer:
B. 0, 1, 2, 3
Step-by-step explanation:
If n were to be 4, the expression would then be incorrect because 36 is not greater than itself. However, if n was 0, 1, 2, or 3, each value would be less than 36, which is what we are looking for.
36 > 9n
36 > 9(0)
36 > 0
Correct!
36 > 9n
36 > 9(1)
36 > 9
Correct!
36 > 9n
36 > 9(2)
36 > 18
Correct!
36 > 9n
36 > 9(3)
36 > 27
Correct!
36 > 9n
36 > 9(4)
36 > 36
Incorrect! This expression would only be correct if the sign was representative of greater than or equal to, rather than just equal to.
I hope this made sense! Have an amazing day. :)
