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
high so I think your answer might be so says each month at least $26 and tap class at her dance studio if each when she spends 30 of her class time in tap class how is the total number of hours spent it in dance class each month show your work or explain how he found your answer in a sentence so basically divide 30 by 6 and then you get your answer which is 5
We have y - 2 = m(x + 5), where m = (-1 - 2)/(10 + 5) = -3/15 = -1/5; Then y - 2 = (-1/5)(x + 5); 5y - 10 = (-1)(x + 5); 5y - 10 = -x - 5; x + 5y - 5 = 0 is the equation of the line.
