without using a calculator decide which option is better value for money: 300g Jelly beans $5.80 or 500g Jelly beans $9.90
yarga [219]

Answer:

500g Jelly beans $9.90

Step-by-step explanation:

To know the values.

Let's know how much a gram will cost in each case

300g Jelly beans $5.80

1g = 5.8/300

1 g = 0.01933

500g Jelly beans $9.90

1g = 9.9/500

1g =0.0198

It's obvious that the second one has more value placed on it as it cost more per gram

If f(x) = 4x - 3 and g(x) = x + 4, find (f - g)(x).
aleksandrvk [35]

Answer:

(f - g)(x) = 3x - 7

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

             = 4x - 3 - ( x + 4 )

             = 4x - 3 - x - 4

             = 3x -7

In the xy-plane, the line determined by the points (2,k) and (k, 32) passes through the origin. Which of the following could be
alexgriva [62]

1) Considering that those points (2,k) and (k,32) determines one same line, within the plane. Therefore we can say that

2) Considering that since they pass through the origin then their x -coordinate is equal to zero, and their y coordinate as well so

3) We can state that as a matter of fact (2, k) and (K, 32) can be rewritten as (2,0) and (0,32)

k=0
