Sounds like 2 parallel lines.

Consider

2x-3y = 5

and

2x-3y = 7

These lines have the same slope and are thus parallel. Parallel lines never intersect. So there is no algebraic or graphical solution.

We'll set up the first two equations so z=1 and the last so it doesn't, no solutions.

x + y + z = 1

x + y + 2z = 2

z = 0

In the expression 2x + x to the power of 2 + 3y, what are the coefficients?

GenaCL600 [577]

Answer:

A coefficient is a number in front of a variable. For example, in the expression x 2-10x+25, the coefficient of the x 2 is 1 and the coefficient of the x is -10. The third term, 25, is called a constant.

Differentiate f and find the domain of f. (enter the domain in interval notation.)f(x) = ln(x2 − 12x)derivative f '(x) = 2x−12x2

guajiro [1.7K]

F(x) = ln(x² - 12x)
The derivative is
$f'(x)= \frac{2x-12}{x^{2}-12x}$

f(x) is undefined when x² - 12x = x(x - 12) = 0
That is, when x = 0 or x = 12.
Therefore the domain is (-∞, 0)∪(0,12)∪(12, ∞)

Answer:
The derivative is
$f'(x) = \frac{2x-12}{x^{2}-12x}$
The domain is
(-∞, 0)∪(0, 12)∪(12,∞)
