(y + 12)^2 + 400 = 0
(x - 5)^2 + 100 = 0
(y + 12)^2 - 400 = 0

I do not think they can, becuase they are missing the middle number with the X

EX: 2x^2 + 4x + 16 = 0
Aren't all of the above equations missing the number where 4x is on this example?

If I am wrong, can you please explain? Thank you.

P.S. You do not have to solve any of these.

Tanya's uncle Joe said he would give her so money so she could open a savings account. He gave her $5000.00. She opened an account with 3% interest. How much interest had the account earned after the first 6 months? Answer is 7.50 (no problem there)
Here is where I couldnt figure out.

If Tanya did not make any withdrawals, how much money was in her account at the end of the first eight months? The answer given is $ 1050.00 ( I couldnt figure how that answer came to be and there were some typo's in this booklet)

A guy walks into a store called 7/11. He selects 4 different items and takes them to the cashier to pay for them. The cashier checks them and asks for $7.11. The guy says thats unusual that the total is the same as the store name. He checks his reciept and discovers that the cashier has multiplied the items instead of adding them, he shows this to the cashier but the cashier says it does not make any difference as the total is still $7.11. What were the 4 prices?

1*1
1*3 2*2 3*1
1*5 2*4 3*3 4*2 5*1
1*7 2*6 3*5 4*4 5*3 6*2 7*1
*
*
*
etc.

If we go on constructing the pattern of numbers above, will each row contain atleast 1 product of two odd prime numbers? If the answer to this can be proven to be yes, then would this prove also Goldbach’s conjecture considering the fact that the sum of any two numbers composing a product in a row adds up to twice the square root of the perfect square contained in that row, and that all even numbers greater then 4 are accounted for in the matrix?

For example, in the row that contains the perfect square 2*2, we have 3+1 = 4, with 3 and 1 odd prime numbers. In the row containing the perfect square 3*3 we have 5+1 = 6, with 5 and 1 odd prime numbers…etc.

Might this be related to Goldbach’s conjecture?

I am completely stumped by this assignment. If you could lend any help I would appreciate it...even a website would be nice!

Here is the assignment:

In the following chart, describe the Transformation: give the domain and range of the translated function. Let f(x) be a simple graph that illustrates the transformations easily and sketch the pre-image and the image for each.

FUNCTION.............CHANGE IN GRAPH.......DOMAIN.......RANGE
1. f(x)
2. g(x)=f(x-c)
3. r(x)=f(x+c)
4. j(x)=f(kx), k>1
5. m(x)=f(kx), 0 6. n(x)=k[f(x)], k<0
7. u(x)=k[f(x)], k>1
8. h(x)=k[f(x)], 0 9. p(x)=f(x)+c
10. o(x)=f(x)-c
11. Q(x)= I f(x) I
12. v(x)=f(-x)
13. s(x)=f(IxI)

I am trying to replicate Robert Barro's results in his 1991 Economic Growth in a Cross Section of Countries paper. I have had problems with the deviation of PPP of investment. I don't know if I am just supposed to obtain the plain difference between the country's value and the sample mean or if this involves more extensive calculation.
