To determine the correct ordered pairs which will agree with the function, we can substitute values to the function and see whether it agree with each other. We do as follows:
<span>(0,1)
</span><span> f(x)=128(0.5)^0
</span><span> f(x)=128
</span><span>
(1,64)
</span><span> f(x)=128(0.5)^1
</span>f(x) = 64 <--------CORRECT ANSWER<span>
(3,16)
</span><span> f(x)=128(0.5)^3
f(x) = 16 <--------CORRECT ANSWER
</span><span>
(8,0.5)
</span><span> f(x)=128(0.5)^8
f(x) = 1/2
Hope this answers the question. Have a nice day.</span>
Answer:
Step-by-step explanation:
For x:
8x = 18 - 2y
x = (18 - 2y)/8
For y:
2y = -8x + 18
y = -4x + 9
Answer: Ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

Step-by-step explanation:
Answer:
£21
Step-by-step explanation:
Sarah : Gavyn = 5:3
Sarah's share = 5x
Gavyn's share = 3x
5x - 3x = 14
2x = 14
x = 14/2
x = £ 7
Gavyn's share = 3x = 3 * 7 = £21
