Answer:

undefined

Step-by-step explanation:

4 - 9 = x - 2

-5 = x - 2

-3 = x

this is a vertical line (parallel to the y-axis) at x = -3.

that means the slope of this line is "undefined". or some would call it "infinite".

as the slope is the ratio of y/x describing how many units y changes, when x changes a certain amount of units.

now the change of x for this line is constant 0.

so, we have a slope y/0, which is undefined.

Simplify 24x5 y6 . A) 2x2 y3 6x B) 4x2 y3 6x C) 6x2 y3 4x D) 6x2 y3 2x
Cerrena [4.2K]

Answer : A 2x^2y^3\sqrt{6x}

\sqrt{ 24x^5y^6}

Take square root for each term and simplify it

\sqrt{24} *\sqrt{x^5}  *\sqrt{y^6}

\sqrt{24}=\sqrt{4 * 6}  = 2\sqrt{6}

\sqrt{x^5} = x^2\sqrt{x}

\sqrt{y^6} = y^3

so we will get

2\sqrt{6} *  x^2\sqrt{x} * y^3

2x^2y^3\sqrt{6x}

Which set represents the zeros of the function f(x) = 7x2 – 28x + 21?
Fantom [35]

Answer:

change f(x) to 0 than 7*2x=14x

0=14x-28x+21

0=-14x+21

-21=-14x

x=3/2

PRACTICE ANOTHER A piece of wire 18 m long is cut into two pieces. One piece is bent into a square and the other is bent into an
sergejj [24]

Answer:

Step-by-step explanation:

We have the equations

4x + 3y = 18   where x = the side of the square and y = the side of the triangle

For the areas:

A = x^2 + √3y/2* y/2

A = x^2  + √3y^2/4

From the first equation x = (18 - 3y)/4

So substituting in the area equation:

A = [ (18 - 3y)/4]^2 + √3y^2/4

A = (18 - 3y)^2 / 16 + √3y^2/4

Now for maximum / minimum area the derivative = 0 so we have

A' = 1/16 * 2(18 - 3y) * -3 + 1/4 * 2√3 y = 0

-3/8 (18 - 3y) + √3 y /2 = 0

-27/4 + 9y/8 + √3y /2 = 0

-54 + 9y + 4√3y = 0

y = 54 / 15.93

= 3.39 metres

So x = (18-3(3.39) / 4 = 1.96.

This is a minimum value for x.

So the total length of wire the square  for minimum  total area is 4 * 1.96

= 7.84 m

There is no maximum area as the equation for the total area is a quadratic with a positive leading coefficient.
