Answer: option A is the correct answer.
Step-by-step explanation:
The expression that relates revenue, profit and cost is
Profit = Revenue - Cost
The revenue from selling x shirts is r(x) = 11x. The cost of buying x shirts is c(x) = 6x + 20. Therefore,
p(x) = r(x) - c(x)
p(x) = 11x - (6x + 20)
By expanding the bracket, the minus sign will alter each term in the bracket. Therefore,
p(x) = 11x - 6x - 20
p(x) = 5x - 20
A line of symmetry basically is like a reflection of a shape, so your answer is D.
The given sequence is a geometric sequence. The property of geometric sequence is that each term is multiplied by a specific number known as "common ratio" to get the next term. In this case the common ratio is 1/2.
2 x 1/2 = 1
1 x 1/2 = 1/2
1/2 x 1/2 = 1/4
and so on..

</u>- The action of simplifying fractions<u /> is dividing the numerator and denominator by a common factor.
- The action of simplifying radicals is making sure the radicand has no square factors. You separate the radicand into two parts, one of which can be square rooted into a whole number.
<em>Example:</em>
speed = distance/time
here, distance = 2,015.3 miles
time = 1 day 15 minutes= 24 1/4 hours = 97/4 hours
speed = 2,015.3 *4 / 97 = 83.10 miles/hour
