Hello,
That means that we must first obtain x, then we replace x in the function to get y, so:
Answer: V=(-4 , -4)
the sine function is a many-to-one function and therefore has no inverse function.
However if the domain is restricted to -90° ≤ x ≤ 90°
Then the function is one-to-one for this domain
Thus, 
x is defined as the angle such that - π/2 ≤ x ≤ π/2
5π/6 is therefore outwith the domain
Answer:
c)
Step-by-step explanation:
16) Cost price = Selling price * 100 / (100- loss%)
= 800 * 100 / 80 = 10*100 = 1000
Loss = Cost Price - Selling price = 1000 -800 = 200
The expression for the total cost of their trip is 7 + 2x + 3y.
As per the question, assuming the number of bottles to be x and number of bags to be y. The equation will have one time fee of admission, product of cost of bottles and number of bottles and product of cost of bags and number of chips bags.
The one time fee and two products will be added to form the expression. Forming the equation now -
Expression = 7 + 2x + 3y
Therefore, the expression of trip when x bottles of water were bought during the visit is 7 + 2x + 3y.
