Answer:
Least cost per kilogram is "$5 for 2.0 kg"
Step-by-step explanation:
To get cost per kilogram, we divide the cost given by the kg given.
1. We need to divide 4 by 1.5 to get cost per kilogram.
Cost/Kg = 
2. We need to divide 5 by 2.0 to get cost per kilogram.
Cost/Kg = 
3. We need to divide 7 by 2.5 to get cost per kilogram.
Cost/Kg = 
4. We need to divide 8 by 2.5 to get cost per kilogram.
Cost/Kg = 
As we can see, the second option costs the least per kilogram.
Answer A. point. To make a plane, it has to have a minimum of 3 lines or more. A line is just a line.
The first one is incorrect
Answer:
A
Step-by-step explanation:
x | y
0 0
1 4
2 n -> 8
3 12
I've rewritten the x-y table so it's easier to read.
Take a point: 2,8. 2 times 4 is 8.
Take another point: 3,12. 3 times 4 is 12.
Ooh, looks like we have a pattern! After testing all the points (which you should always do in case there's an outlier) each x is multiplied by 4 to get the y. The formula for this is <u>y=kx,</u> where k is the constant of proportionality. So the equation is <u>y=4x.</u> This means x and y are directly proportional.
(They would be inversely proportional if in the form y=k/x; jointly proportional if they were in the form z=kxy, and nonproportional if there was no relationship at all.)
