Solve y=10x^3 + 5.5x^2 - 58.50x + 45.00
WITCHER [35]

Answer:

  x ∈ {-3, 1.2, 1.25}

Step-by-step explanation:

"Solve" is non-specific as to the solution required. We assume you want the x-intercepts.

A graph shows the zeros to be ...

  • x = -3
  • x = 1.2
  • x = 1.25

The equation can be factored as ...

  y = (1/2)(x +3)(4x -5)(5x -6)

A mixture of alcohol and water contains a total of 36 oz of liquid. There are 9 oz of pure alcohol in the mixture. What percent
katen-ka-za [31]

First, we can start off with a fraction:

9/36 = 1/4

Now that we have this fraction, we multiply by 25:

25/100

This can be changed into a percent:

25%

100 - 25 = 75

25% is alcohol and 75% is water
