For this case we have the following equation:
 y = 4 (x-2) ^ 2-1
 Rewriting we have:
 y = 4 (x ^ 2-4x + 4) ^ 2-1
 Multiplying the common factor 2 we have:
 y = 4x ^ 2-16x + 16-1
 Adding the constant term we have:
 y = 4x ^ 2-16x + 15
 Answer:
 
y = 4x ^ 2-16x + 15

Answer: Stephon can buy total 4 chips bag and 2 candy bar

Step-by-step explanation:Given as :

The money which Stephon has in his pocket = $ 12

The cost of one chips bag = $ 2.25

The cost of one candy bar = $ 1.50

The total number of items he can buy = 6

So, Let the number of chips bag he can buy = x

∴ The number of candy bar he can buy = 6 - x

Now, according to question

The number of chips bag×The cost of one chips bag + The number of candy bar×The cost of one candy bar = $ 12

Or, x × $ 2.25 + (6-x) × $ 1.50 = $ 12

Or,  x × $ 2.25 + 9 -  x × $ 1.50 = $ 12

or,  x × $ 0.75 = 12 - 9

or, x =  = 4

The number of chips bag he can buy = x = 4

And The number of candy bar he can buy = 6 - x = 6 - 4 = 2

Hence Stephon can buy total 4 chips bag and 2 candy bar .

solmaris [256]

Answer:

Its the last option

y = 1488.33x + 23800 ; $172,600.

Step-by-step explanation:

The slope of the trend line = (median value for 2000 - median value for 1940) / 60

= 89300 / 60

= 1488.33.

So the equation is 1488.33x + 23,800

Estimate for 2040

is 1483.33* 100 + 23800

= 172,600.
