Assignment: \bold{Solve \ Equation: \ \left(x^2-9x+2\right)+\left(4x^2-5x+1\right)-\left(5x^2-5\right)}

<><><><><><><>

Answer: \boxed{\bold{-14x+8}}

<><><><><><><>

Explanation: \downarrow\downarrow\downarrow

<><><><><><><>

[ Step One ] Remove Parenthesis: (a) = a

\bold{x^2-9x+2+4x^2-5x+1-\left(5x^2-5\right)}

[ Step Two ] Simplify \bold{-\left(5x^2-5\right)}

\bold{-5x^2+5}

[ Step Three ] Rewrite Equation

\bold{x^2-9x+2+4x^2-5x+1-5x^2+5}

[ Step Four ] Simplify \bold{x^2-9x+2+4x^2-5x+1-5x^2+5}

\bold{-14x+8}

The sum of four times a number and five times another number is -28. The sum of nine times the first number and two times the se
dedylja [7]

Answer:

  -8

Step-by-step explanation:

If we let x and y represent the first and second numbers, respectively, we can write the problem statement as the equations ...

  • 4x +5y = -28
  • 9x +2y = 11

We can multiply the first equation by -9 and add 4 times the second equation to get an equation in y alone:

  -9(4x +5y) +4(9x +2y) = -9(-28) +4(11)

  -37y = 296 . . . . . simplify

  296/-37 = y = -8 . . . . . divide by the coefficient of y

The second number is -8.

An experiment observes an integer uniformly chosen from {1.2, 3.4.5, 6, 7, 8, 9, 10, 11.12}
Brrunno [24]

Answer:

Options D & E are independent

Step-by-step explanation:

For any of the options to be independent, they have to be mutually exclusive i.e A ∩ B = 0

A) A ∩ B = {1, 2, 3}. They are not mutually exclusive and so they are not independent.

B) A ∩ B = {3}. They are not mutually exclusive and so they are not independent.

C) A ∩ B = {8}. They are not mutually exclusive and so they are not independent.

D) A ∩ B = 0. They are mutually exclusive and thus they are independent.

E) A ∩ B = 0. They are mutually exclusive and thus they are independent.
