Answer:

Step-by-step explanation:

Slope = (y2-y1)/(x2-x1)

= (4-2)/(-5-(-5))

= 2/0

Which is undefined

Alternately,

Since both points have x-coordinate of -5, they lie on the line x = -5

which is a vertical line (parallel to y-axis).

Every vertical line has an undefined slope

The slope is undefined, because the x values are the same.

Solve 5x(x-6)(4x+9)=0

Greetings and Happy Holidays!

Solve for x.
$5x(x-6)(4x+9)=0$ <span>

Distribute the parenthesis:
</span> $5x(x-6)(4x+9)=0$

$(5x^2-30x)(4x+9)=0$

$(20x^3-120x^2)+(45x^2-270x)=0$

Combine like terms:
$20x^3-75x^2-270x=0$

Factor out GCF (5x):
$5x(4x^2-15x-54)=0$

Factor the Complex Trinomial:
$5x(4x^2+9x-24x-54)=0$

$5x(x(4x+9)-6(4x-9))=0$

$5x((4x+9)(x-6))=0$

Set Factors to Equal 0:
$5x=0$

$x=0$

or

$4x+9=0$

$4x=-9$

$x=\frac{-9}{4}$

or

$x-6=0$

$x=6$

The Answers Are:
$\boxed{x=0} \\ \boxed{x= \frac{-9}{4}} \\ \boxed{x=6}$

I hope this helped!

Need help ASAP DUE SOON AND PLEASE SHOW WORk!!!!

Answer:

87.92 inches cubed or 87.92 in.^3

Step-by-step explanation:

The base of a cylinder is a circle, so we need to calculate the area of the circle first. The equation for the area of a circle is:

area (a) = pi * r^2 =3.14*2*2 =12.56sq.inches

again,

volume of cylinder = area of the base * the height

= 12.56 * 7

= 87.92 inches cubed or 87.92 in.^3

Find X if m/_ UVH=50°, m/_HVW=25x-5, and m/_ UVW = 35x-5.

ra1l [238]

Step-by-step explanation:

first you have to solve for x

35x - 5=50

35-35x-5= 50-35

x-5=15

x- 5÷5=15÷5

x=3

Now we have to substitute x into the equation.

35×(3)-5=

175-5=170

angle UVW= 170

to find angle HUW instead of solving the equation just subtract 170 from 50 and you will get 120.

angle UVH=50

angle HUW=120

angle UVW=170

I hope this helps srry it took so long but gn and gl.
