To subtract vectors, subtract the x coordinates together. Do the same for the y coordinates as well.
In terms of a formula if we had the vectors u and v such that
u = <a,b>
v = <c,d>
then
u - v = <a-c, b-d>
Let's use that to get...
u - v = <6,-9> - <1,-4>
u - v = <6-1,-9-(-4)>
u - v = <6-1,-9+4>
u - v =
<5,-5>----------------------
Answer: A) <5,-5>
Just put it in a calculator, it’s 3600 divided by 40
The article for the assignment I need help with part 2
Answer:
f(x) = 1000x + 3000
Step-by-step explanation:
the point (0,3000)
p2 (1,4000)
slope = (y2-y1) / (x2-x1)
= (4000 - 3000) /( 1-0)
slope = 1000 = m
y = mx + b
y=1000x + b
Use one of the points to find b :
3000 = 1000(0) + b
b = 3000
f(x) = 1000x + 3000
