It’s the second one I think
0.45 is bigger than 2/5. Hope this helps.
Answer:
-1.5-32-16ij
Step-by-step explanation:
When you substitute it you will get (3i+8j)(-0.5i-4j)
Then you will use FOIL
From this, you get -1.5-32-16ij
It is 30 feet BELOW the platform, so the number is -20 because the platform is 10 feet above ground level.
Her elevation is - 20 because she is 10 feet above ground level, which is 10, and she digs 30 feet down so 10 - 30 is -20.
Hope this helps. :)
j=2
Step-by-step explanation:
take the second numbers in each parentheses and subtract them. put this answer on top of a fraction
(j,3) (8,2)
2-3 = -1
take the first numbers and subtract. put this answer at the bottom of fraction
8 - J = 6
j = 2
answer should equal -1/6
the formula for a slope is y2-y1/x2-x1
look at the points like this, and fill in the places with the numbers and j they give you
(X1,y1) (X2,y2)
