Answer:
x=1.875 y=-0.875
Step-by-step explanation:
10x-3y=3 10x-3y=3
3(2x+y)=(9)3 +<u>6x+3y=27</u>
1/16(16x)=(30)1/16 = x=1.875
10x-3y=3 10x-3y=3
-5(2x+y)=(9)-5 -<u>10x-5y=4 </u>
1/-8(-8y)=(7)1/-8 = y=-0.875
Y = 7x + 12.....x = number of tickets and y = total cost
and there are 4 tickets ordered (Frank and 3 friends)...so x = 4
y = 7(4) + 12
y = 28 + 12
y = 40 <=== so he paid 40 bucks for them
The answer is 1/2=2PiN=2Pi/T, so the period is T=4Pi
