Remember, to solve this, you multiply the bigger numbers and add the exponents. if the exponents are negative they go on the bottom and are switched to a positive, you are trying to make the problem positive.
number 15 is A because you multiply 2 and 4 to get 8 and you add the exponents together if they are positive and are not a fraction
number 16 is D because you multiply all the bigger numbers together to get 48, then you add all the b's together to get four and all the a's to get 8
number 17 is D because you do the same by multiplying 5 and 3 to get 15, then adding the exponents to get 3 x's and 6 y's
number 18 is D because you multiply 5 and 2 and add the exponents to get 3 x's and 5 y's because the x without a number is a one so you make that one count and add 2 and one together to get 3
number 19 is B because the smaller number is negative so the y goes to the bottom and it becomes a y^3
number 20 is A because both exponents are negative and go to the bottom and become positive
number 21 is D because its the same case as number 20
Lastly Number 22 is B
I hope this helps and is correct lol
Answer:
$ 2.33
Step-by-step explanation:
Fair game is when expected profit = 0

Answer:
26.8 inches of fabrics was used on headband and wristband for each player
Step-by-step explanation:
Headbands for 31 players and 3 couches = 611.66 inches of fabric
Total number of people = 31 players + 3 couches
= 31 + 3
= 34 people
Fabrics per person's headbands = Total inches of fabrics for headbands / total number of people
= 611.66 inches of fabric / 34 people
= 17.99 inches of fabrics per person
Wristband for 31 players = 273.11 inches of fabric
Fabric per person's wristband = total inches of fabrics for wristband / number of players
= 273.11 inches of fabric / 31
= 8.81 inches per person
How much fabric was used on a headband and wristband for each player?
= Fabrics per person's headbands + Fabric per person's wristband
= 17.99 inches + 8.81 inches
= 26.8 inches of fabrics was used on headband and wristband for each player
Y = 2 x + 3
We will plug in the numbers from the sets:
1 = 2 · ( -1 ) + 3 = - 2 + 3= 1 ( correct )
3 = 2 · 0 + 3 = 0 + 3= 3 ( correct )
7/3 = 2 · (-1/3 ) + 3 = -2/3 + 3 = - 2/3 + 9 /3 = 7/3 ( correct )
Answer : A ) { (-1, 1 ), ( 0, 3 ) , ( -1/3, 7/3 ) }
