Answer:

A. (4, 5) and C. (0, -3).

Step-by-step explanation:

A. 5 = 4 * 4 - 2 * 4 - 3

5 = 16 - 8 - 3

5 = 8 - 3

5 = 5

5 = 2 * 4 - 3

5 = 8 - 3

5 = 5

A. (4, 5) is a solution.

B. 0 = 1 + 2 - 3

0 = 0

0 = -2 - 3

0 IS NOT EQUAL TO -5

B. (-1, 0) is not a solution.

C. -3 = 0 - 0 -3

-3 = -3

-3 = 0 - 3

-3 = -3

C. (0, -3) is a solution.

D. 0 = 9 - 6 - 3

0 = 9 - 9

0 = 0

0 = 6 - 3

0 IS NOT EQUAL TO 3.

D. (3, 0) is not a solution.

So, your answers are A. (4, 5) and C. (0, -3).

Hope this helps!

A store had 50 bottles of olive oil. Each week, 40% of the olive oil bottles were sold and 20 new bottles arrived in shipments.
Wittaler [7]

Answer:

f(n) = f(n − 1) ⋅ 0.6 + 20, n > 0

Step-by-step explanation:

Each week 40% of the olive oil bottles were sold. This means, each week 60% of the bottles were left. In addition to these, 20 new bottles arrived in shipments.

So, every week the number of shipments was:

60% of the shipments of previous week + 20

In equation form this can written as:

Shipments in a week = 60% of shipments of previous week + 20

For, nth week we can re-write this equation as:

f(n) = 60% of f(n - 1) + 20

or

f(n) = f(n - 1) ⋅ 0.60 + 20

For example for first week, replace n by 1 to find the number of shipments in week 1 and same goes for next weeks.
