Answer:
B. 100
Step-by-step explanation:
![3y+4+7y+9=143](https://tex.z-dn.net/?f=3y%2B4%2B7y%2B9%3D143)
143-13=130
10x=130 divide both sides by 10 130/10= 13 x=13
MN=7(13)=91+9=100
LN=3(13)=39+4=43
100+43
2 boxes for $6.00 5 Bars each is 10 bars for $6.00 or $3.00 for 5 bars
so $6.00 divided by 10 =.60 or 60 cents per bar
12 bars for $7.44 is $7.44 divided by 12 =.62 or 62 cents per bar
so the difference between 60 cents and 62 cents is
2 cent Difference
Answer:
Amplitude = 1/2
Period = ![\dfrac23 \pi](https://tex.z-dn.net/?f=%5Cdfrac23%20%5Cpi)
Phase shift =
(left)
Vertical shift = ![-3](https://tex.z-dn.net/?f=-3)
Step-by-step explanation:
![f(x)=-\dfrac12cos(3(x+\pi))-3](https://tex.z-dn.net/?f=f%28x%29%3D-%5Cdfrac12cos%283%28x%2B%5Cpi%29%29-3)
![y = A sin(B(x + C)) + D](https://tex.z-dn.net/?f=y%20%3D%20A%20sin%28B%28x%20%2B%20C%29%29%20%2B%20D)
Amplitude is A = 1/2
Period is
= ![\dfrac23 \pi](https://tex.z-dn.net/?f=%5Cdfrac23%20%5Cpi)
Phase shift is C=
