9,000,000,000 + 3,000,000 +800,000 +40,000 + 100 + 60 +5
2/(x-4)-1/(x+3)
(2(x+3)-1(x-4))/(x-4)(x+3)
(2x+6-x+4)/(x-4)(x+3)
(x+10)/(x-4)(x+3)
3.49/25 = $0.14 per ounce
4.79/40 = $0.12 per ounce
Choice B has a lower price per ounce
Answer: (x+5)^2+(y-2)^2=81
Step-by-step explanation:
Answer:
0.5amps
Step-by-step explanation:
I is inversely proportional to resistance
I = k/R
k = I/ R
k = 20/5
k = 4
This means that, I = 4/R
So, when R = 8ohms,
I = 4/8
=0.5amps
