105.91 is the answer for you
Answer:
2204.4
Step-by-step explanation:
Okay so we want to always use order of operations: PEMDAS
Sop first we do what is in the parenthesis. 19*92 is 1748.
Now, going from left to right, we do multiplication and division. 76*32 is 2432. Then we divide that by 5 to get 486.4. And the last bit is 15*2 which is 30.
Your equation now is 486.4+1748-30.
The final answer is 2204.4
Answer:
Option D
Step-by-step explanation:
We are given the following equations -

It would be best to solve this equation in matrix form. Write down the coefficients of each terms, and reduce to " row echelon form " -
First, I swapped the first and third rows.
Leading coefficient of row 2 canceled.
The start value of row 3 was canceled.
Matrix rows 2 and 3 were swapped.
Leading coefficient in row 3 was canceled.

And at this point, I came to the conclusion that this system of equations had no solutions, considering it reduced to this -

The positioning of the zeros indicated that there was no solution!

Recall that the vertex form of a quadratic function (or parabolic function) is equal to

Now, given that we have f(x) = x² + 14x + 40, to express f into its vertex form, we must first fill in the expression to form a perfect square.
One concept that we must remember when completing the square is that
(a + b)² = a² + 2ab + b²
So, to complete the square for (x² + 14x + ____), we have 2ab = 14 where a = 1. Thus, b = 14/2 = 7. Hence, the last term of the perfect square must equal to 7² = 49.
So, going back to the function, we have




Thus, we have derived the vertex form of the function.
Answer: f(x) = (x + 7)² - 9
