Find all the zeroes of the equation. -3x4+27x2+1200=0 I need to learn how to do it! Just not the answer please
Mumz [18]
The first thing you should do for this case is to rewrite the expression.
 To do this, divide both sides of the equation between -3.
 We have then:
 (-1/3) * (- 3x ^ 4 + 27x ^ 2 + 1200) = (- 1/3) * (0)
 x ^ 4-9x ^ 2-400 = 0
 Then, we rewrite the polynomial:
 (x-5) * (x + 5) * (x ^ 2 + 16) = 0
 From here, we obtain the four roots:
 Root 1:
 x-5 = 0
 x = 5
 Root 2:
 x + 5 = 0
 x = -5
 Root 3 and root 4:
 x ^ 2 + 16 = 0
 x3 = -4i
 x4 = 4i

 Answer:
 all the zeroes of the equation are: 
 x1 = 5 
 x2 = -5
 x3 = -4i
 
x4 = 4i

Find the slope of a ski run that descends 15 feet for every horizontal change of 24 feet.
Serhud [2]
A common way of remembering slope is "Rise over Run," meaning vertical change divided by horizontal change. For your question that would be -15 (because it's going down) divided by 24 => -15/24 => -5/8
Final answer:
The slope is -5/8 feet.
Hope I helped :)

How many solutions for the equation, 8x - 19 = -4 -7x
Goryan [66]

Answer: One.

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :   8*x-19-(-4-7*x)=0

Pull out like factors :   15x - 15  =   15 • (x - 1)

 Solve :    15   =  0

Solve  :    x-1 = 0  

 Add  1  to both sides of the

What rule describes a dilation with a scale factor of 4 and the center of dilation at the origin?
kompoz [17]

Answer: (x,y)---->(4x,4y)

Step-by-step explanation:

 1. By definition, dilation is as a transformation in which the figure is enlarged or reduced.

2. For dilation you have:

- A scale factor, that determines how much the figure will be reduced or enlarged.

- The center of dilation, which is defined a a fixed point in the plane.

3. If the figure is dilated with a scale factor of 4 and the center of dilation at the origin, you must multiply each coordinate of the original figure by 4, then. Then, the rule is:

(x,y)---->(4x,4y)
