3m^2-m-2=0  is of the form ax^2+bx+c

Find two values, j and k, which satisfy two conditions:

jk=ac=-6 and j+k=b=-1, so j and k must be 2 and -3

Now replace bx with jx and kx to get:

3m^2-3m+2m-2=0 now factor 1st and 2nd pair of terms

3m(m-1)+2(m-1)=0

(3m+2)(m-1)=0 so 

m=-2/3 and 1

An item that has been marked up sells for a profit. If an item sells that has been marked down, can it still produce a profit? E
lana66690 [7]

Yes, it can. On most things (especially clothes and furniture) they will be already marked up 100% before the mark down. For example; even if they have a, let's say, 40% off sale on the shirt, they will still make a 10% profit off the shirt. So pretty much in most cases, there will still be a profit out of the merchandise.

This is for the Journal Activity on e2020. The words required to pass the written response are as follows: Yes, profit, less, more, greater, much.

Use any 2 of those words in your response and you will pass it.

Have a good day everyone! :)
