Yay, love these ones.

First of all, (4x-+3)(-2x-5) is the same as (4x-3)(-2x-5)
So the method for solving these can be remembered by FOIL.
F= Firsts   O= Outsides   I= Insides   L= Lasts

In other words everything is multiplied by everything, for example:
4x * -2x and -3 * -5 <span>is the firsts of the brackets multiplied and last of the brackets mulitplied
</span>
4x * -5 and 3 * -2x is the outsides of the brackets multiplied and the insides of the brackets multiplied
<span>
The SUM of FOIL is then added:</span><span>
</span><em>4x*-2x = -8x^2</em>
<em>-3*-5= 15</em>
<em>4x*-5=-20x</em>
<span><em>3*-2x=-6x</em>
</span><span>-8x^2 -20x -6x + 15 = 0
-8x^2 -26x + 15 = 0

So the factored of (4x-3)(-2x-5) <u /><em>=</em> -8x^2 -26x + 15 = 0

So then you graph that equation on your given grid

Can i get some help with these LCD equations please.
Andre45 [30]

Answer:

  y = -1/4

Step-by-step explanation:

  y/5 +3/10 = (y+2)/7

The LCD is 10·7 = 70. Multiplying the equation by 70 gives ...

  14y +21 = 10(y +2)

  14y +21 = 10y +20 . . . . eliminate parentheses

  4y + 21 = 20 . . . . subtract 10y

  4y = -1 . . . . . . . . . subtract 21

  y = -1/4 . . . . . . . . .divide by 4

_____

<em>Check</em>

  (-1/4)/5 +3/10 = (-1/4 +2)/7 . . . . . substitute for y

  -1/20 +6/20 = (7/4)/7 . . . simplify a bit, rewrite 3/10

  5/20 = 1/4 . . . . . . . . . . true

How many leaves on a tree diagram are needed to represent all possible combinations tossing a coin and rolling a dice
dolphi86 [110]
The total number of outcomes of rolling a die      = 6
The total number of outcomes of  tossing a coin = 2

The total number of possible outcomes of executing both experiments is 6*2=12, which is also the number of leaves (end of the branch of a tree) on a tree diagram.
