Guy finds how far his house is from several locations and make the table shown. How much farther away from Guy's house is the li

lisov135 [29]

So, we've got two important and useful information:
guy's house is 9/10 miles away from the library
guy's house is 4/10 miles away from the cafe
now, the question will tell us which mathematical operation to use, it says:
how much farther than. that means comparing which means difference which means subtraction. (how much farther than=comparing=differnce=subtraction)
so now we know that we will subtract. but, subtact which number from which number? we need to subtract 4/10 from 9/10 which means it will be equal to 5/10 which can be simplified into 1/2
the answer is basically 5/10 and if you want to look smart for your teacher, you must write simplified=1/2..

hopw this helps... now.. for return i need the brainliest answer.. :) :D

Solve using quadratic formula x squared -2x-8=0

Aleks [24]

$x= \frac{-b\pm \sqrt{b^2-4ac} }{2a}$ for the equation $ax^2+bx+c$

Your question is $x^2-2x-8=0$

So $a=1 \\b=-2\\c=-8$

So plug in your numbers:
$x= \frac{-(-2)\pm \sqrt{(-2)^2-4(1)(-8)} }{2(1)}$

Simplify:
$x= \frac{2\pm \sqrt{4-(-32)} }{2}$

Simplify a little more:
$\frac{2\pm6}{2}$

So our answer is<u />
$x= \frac{2+ 6 }{2} = 4\\x= \frac{2- 6 }{2}=-2$

So $x=4, x=-2$
