When x increases from a to a + 2, y increases by a factor of 16. For which functions is this statement true?

I think the correct answer would be option B. When x increases from a to a + 2, y increases by a factor of 16. The function that best describe this would be y = 4^(x + 2). Hope this answers the question. Have a nice day. Feel free to ask more questions.

A lady buys 20 trinkets at a yard sale.

Katen [24]

Answer:

Lady purchased 12 trinkets costing $0.30 each and 8 trinkets costing $0.65 each.

Step-by-step explanation:

A lady buys total number of trinkets = 20

Cost of each trinket is either $0.30 or $0.65.

Let the number of trinkets is x she purchased for $0.30 and y for $0.65

Then x + y = 20 --------(1)

Since she spends total amount = $8.80

Then the equation will be

0.30x + 0.65y = 8.80 ---------(2)

We replace x = (20 - y) from equation (1) to equation (2)

0.30(20 - y) + 0.65y = 8.80

6 - 0.30y + 0.65y = 8.80

0.35y + 6 = 8.80

0.35y = 8.80 - 6

0.35y = 2.80

y = $\frac{2.80}{0.35}$

y = 8

Now we put y = 8 in equation (1)

x + 8 = 20

x = 20 - 8

x = 12

Therefore, lady purchased 12 trinkets costing $0.30 each and 8 trinkets costing $0.65 each.

pychu [463]

Sid and Libby are planning to sell pies at a local fair.
=> $200 to rent a table at the fair.
=> $3.00 per pie costs for ingredients, other supplies, baking, and packaging
They plan to sell the pies for $8 each.
Let's find out how many pies will they be selling inorder to gain profit
=> 200 + 3.00(n) = 8(n), where n is the number of pie.
Let's try 40
=> 200 + 3(40) = 8 (40)
=> 320 = 320
=> 200 + 3(41) = 8 (41)
=> 323 = 328
Thus, in their 41st pie, they will get a profit
