<u>Answer:</u>
Stanley factored it correctly.
<u>Step-by-step explanation:</u>
We are given that Marie and Staley factored the above expression as follows and we are to determine who factored it correctly:
Marie: --->
= so this is wrong.
Stanley: --->
=
Therefore, Stanley factored it correctly.
-2=-x+x square-4
firstly regroup the equation
x square-2x+x-2=0
x square-x-2=0
multiply the first term by the last term.(I.e x square multiply by -2=-2x square)
product of factor = -2x 1
sum of factor= -2x+1(x)= -1
x square -2x+x-2=0
open the bracket:
x(x-2)+1(x-2)=0
x=1 or x=-2
Therefore; x=-1 or x=2
Answer: -3
Since the both equal the same value we can combine the into -8x-2=-6x+4.
From there you can solve from whatever side you want, and the answer is -3.
General form of a line :
The slope-intercept form:
m - slope
b - y-intercept
We have
a slope and y-intercept.
Substitute:
<em>multiply both sides by 3</em>
<em>subtract 3y from both sides</em>
<em>change the signs</em>
the problem would be set up as 6+(7*x)=41
first u take off the number 6 by subtracting it from itself to cancel it out then u do the same to the number 41
7x =41 now u need to cancel out the number 7 attatched to the x so u divikde it by itself and then do the same to the other side so 41 divided by 7 =5.9
so x =5.9
