x = 3 and y = -3
Step-by-step explanation:
To start, let's double the first equation to get 6x + 2y = 12. Add this to the second equation to get 10x = 30, so x = 3 and y = -3.
Answer:
p=32-c (*Units in million $)
Step-by-step explanation:
Let r be the revenue realized in any given year.
-Given that c=cost and p= revenue
#We notice that the profit, cost or revenue realized in one year is independent of the prior or subsequent year.
-Therefore, the revenue function is independent of time and is expressed as:

Hence, the yearly profit for any given year is expressed as p=32-c (*Units in million $).
Answer:
0
Step-by-step explanation:
Put 0 where x is and do the arithmetic.
R(0) = 2(0) = 0
P(R(0)) = P(0) = 3(0)
P(R(0)) = 0
Answer:
$420
Step-by-step explanation:
First convert the room measurements from feet to yards to match the unit of measure of the carpet.
Room size is 12 feet by 21 feet.
3 feet = 1 yard.
12/3 = 4 yards
21/3 = 7 yards
4 yards times 7 yards = 28 square yards
28 square yards times $15 per square yards = $420.
