5. Esmy

I don't have a calculator which makes it harder you think you can help me with another...

6. jessip12

yeah

7. Esmy

Find the product, AB, if possible. 0 -3 -2 0 A= 2 1 B= -1 1

8. jessip12

3 -3 -5 1

9. Esmy

Perform the indicated operation. -1 2 5 1 -1 4 6 -1 8 5 3 2 Let A= -4 5 7and B= -9 8 5 Find A - B

10. Esmy

That one and one more that I really need help on and thats it.

11. jessip12

Solve the problem. A company makes three chocolate candies: cherry, almond, and raisin. Matrix A gives the amount of ingredients in one batch. Matrix B gives the costs of ingredients from suppliers J and K. Multiply the matrices. Sugar choc milk J K 6 8 1 cherry 4 3 Sugar 6 4 1 almond 4 5 choc A= 5 7 1 raisin B=2 2 milk My answer is but not to sure :/ Jk 58 60 Sugar 42 40 Choc 50 52 milk

14. Esmy

So im guess I was wrong

15. Esmy

I kinda knw how to do them its just hard a lil hard for me :l

16. jessip12

you got the last one right

17. jessip12
