Help please !! don’t understand

Mathematics
1 answer:
nikdorinn [45]3 years ago
4 0

Step-by-step explanation:

For two lines to be parallel they must have the same slope that is,M1=M2

For two lines to be perpendicular the slope of one must be the negative reciprocal of the other

Let's first find the slope of all three lines.

For line 1

6x-6=10y

2/5x-2/5=y

slope=2/5

For like 2

slope=5/3

For line 3

y=5/3x+2/3

We can therefore say that:

line 1 and line2 are neither parallel nor perpendicular

line 1 and line 3:

neither parallel nor perpendicular

line 2and line 3:

parallel lines

What is the maximum number of possible extreme values for the function,<br> f(x) = х2 -7x – 6?
timama [110]

Answer:

Only one extreme value of f(x) is possible.

Step-by-step explanation:

We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)

Now. the condition for extreme values of f(x) is \frac{df(x)}{dx} =0

Hence, differentiating both sides of equation (1) with respect to x, we get

\frac{df(x)}{dx} = 2x -7 = 0

⇒ x = 3.5.

So there is only one value of x for which f(x) has extreme value which is x = 3.5.

Therefore, only one extreme value of the given function is possible. (Answer)
