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)
Answer:
True
Step-by-step explanation:
The perimeter is the combined length of all the side lengths of a figure.
Divide 1107 by 10, for example:
1107/10= 110.7
The decimal point means the remainder, this means John will only get 7 chocolate bars.
If You want it split evenly between ALL of them, divide by 1107 by 11, for example:
1107/11= 100.6, which would leave six bars left, so I think the logical offer would be the first answer I gave you.
I hope this helped!
Z = -2/3a
divide by -2/3 on both sides
a = z divided by -2/3
a = -3/2z
