Answer:
(x-6) (2x+1)
Step-by-step explanation:
1) move everything over to the left side, so subtract 11x and 6.
2x^2 -11x - 6 = 0
2)multiply 2(a term) with -6 (c term)
x^2 -11x -12
3) factor and find what multiples to -12 and adds up to -11. in this case its -12 and positive 1
(x-12) (x+1)
4) divide -12 and 1 by the original a term (2)
(x-6) (x+1/2)
5) move the denominator of 2 over to the x.
(x-6) (2x+1)
32. 5^-2=1/25
5^-1=1/5
5^0=1
5^1=5
5^2=25
5^3=125
The domain are -2,-1,0,1,2,3,
The range are 1/25,1/5,1,5,25,125
So as the domain increases so does the range
Answer:
x = 2 1/2
Step-by-step explanation:
The place value changes depending on where the # is. example 627 since the 7 is last its in the ones place. the two is in the tens and the 6 is in the hundreds
ANSWER TO QUESTION 1
The given function is

The partial derivative of f with respect to x means we are treating y as a constant. The first derivative is

and the second derivative with respect to x is,

ANSWER TO QUESTION 2
The given function is

The partial derivative of f with respect to y means we are treating x as a constant. The first derivative is

and the second derivative with respect to y is

ANSWER TO QUESTION 3
Our first mixed partial is

We need to differentiate

again. But this time with respect to y.
Since this is a product of two functions of y, we apply the product rule of differentiation to obtain,


ANSWER TO QUESTION 4
The second mixed partial is

We need to differentiate

again. But this time with respect to x.
Since this is a product of two functions of x, we apply the product rule of differentiation to obtain,


Hence,
