So, let's begin...
First off, you must note that the question is asking for the d value when you substitute the value of c(x).
You are given the following information:
1. The c(x) value is already given to be 0.75x.
2. The equation to find d of (any value) is 0.8y-5.
So, substitute the value of 0.75x as a y value into 0.8y - 5. This is because you are substituting the value of c(x) for d. This is equal to 0.8 times 0.75x - 5. This is equal to 0.6x - 5, which is the function. Thus, your final answer is d(c(x)) = 0.6x - 5.
If you have any questions please comment. Otherwise, hope this helps! :)
B) 64, because all these numbers have a difference of 14, and it you keep going, the 10th term will be 64.
Answer is D.
As we can observe, in column y
3,4,6,10,18
4-3 = 1
6-4 = 2
10-6 = 4
18-10 = 8
that other answer is a virus dont click it
cell wall : gives plant cell its shape, rigid
cell membrane: more selectively controls what goes in and out of the cell, acts like a skin
dunno about grid
The yearly cost for a non-member would be : y = 0.20x
