Given Function : f(x) = x² - 9

We can notice that : The function f(x) is zero for only two values of x and they are -3 and 3

⇒   f(-3) = (-3)² - 9 = (9 - 9) = 0

⇒   f(3) = (3² - 9) = (9 - 9) = 0

⇒   The ordered pairs of the zeroes : (-3 , 0) ; (3 , 0)

Determine which of the lines, if any, are parallel. Explain.
MariettaO [177]

Answer:

Parallel lines have same slope but different y-intercept

None of the given equations have same slope. Therefore lines are not parallel.

Step-by-step explanation:

Slope of Line a: 4y +x=8 is -1/4

Slope of Line b: 2y + x = 4 is -1/2

Slope of Line c: 2y = -3x + 6 is -3/2

I don't know how to solve it.
Nataly [62]

Step-by-step explanation:

Take the first derivative

\frac{d}{dx} ( {x}^{3}  - 3x)

3 {x}^{2}  - 3

Set the derivative equal to 0.

3 {x}^{2}  - 3 = 0

3 {x}^{2}  = 3

{x}^{2}  = 1

x = 1

or

x =  - 1

For any number less than -1, the derivative function will have a Positve number thus a Positve slope for f(x).

For any number, between -1 and 1, the derivative slope will have a negative , thus a negative slope.

Since we are going to Positve to negative slope, we have a local max at x=-1

Plug in -1 for x into the original function

( - 1) {}^{3}  - 3(  - 1) = 2

So the local max is 2 and occurs at x=-1,

For any number greater than 1, we have a Positve number for the derivative function we have a Positve slope.

Since we are going to decreasing to increasing, we have minimum at x=1,

Plug in 1 for x into original function

{1}^{3}   - 3(1)

1 - 3 =  - 2

So the local min occurs at -2, at x=1

Use the figure to find x.
velikii [3]

Answer:

Step-by-step explanation:

The sides of a 30-60-90 triangle are in the ratio 1:√3:2

The side opposite the 30° angle is (12√6)÷2 = 6/√6.

The side opposite the 60° angle is √3×6/√6 = 6/√2 =3√2.

The sides of a 45-45-90 triangle are in the ratio 1:1:√2

The hypotenuse is 3√2, so the side opposite the 45° angle is 3.

x = 3
