Answer:
Remove parentheses.
y-10=-3\times -2y−10=−3×−2
2 Simplify 3\times -23×−2 to -6−6.
y-10=-(-6)y−10=−(−6)
3 Remove parentheses.
y-10=6y−10=6
4 Add 1010 to both sides.
y=6+10y=6+10
5 Simplify 6+106+10 to 1616.
y=16y=16
Answer:
52.63
Step-by-step explanation:
(2, -5) is the mid point
(3, 6) is (2+1, -5+11) is an end point
therefor the other end point should be (2-1, -5-11) = (1, -16)
You could visualise this better if you draw it
Hope this helps, I don't really know a better way to explain it, sorry =P
Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:
2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)
(4,8) - (-4,12) = (8,-4)
So the vector has the coordinates (8,-4)
the answer is A couse divide all 5
