Answer:
b. (10,10,0)
Step-by-step explanation:
r+v can be evaluated if the vectors/matrices have the same dimensions.
These do. They are both 1 by 3 vectors.
Just add first to first in each.
Just add second to second in each.
Just add third to third in each.
Example:
(5,-5,6)+(1,2,3)
=(5+1,-5+2,6+3)
=(6,-3,9)
Done!
In general, (a,b,c)+(r,s,t)=(a+r,b+s,c+t).
r+v
=(7,3,9)+(3,7,-9)
=(7+3,3+7,9+-9)
=(10,10,0)
Done!
2 x 14 = 28
28/13 rounds off to 2.15.
9 * 1/3 is 3.
2.15 - 3 = -0.85
Or -17/20.
Answer: 1/4 times 5
Step-by-step explanation: gtg sorry don’t have time
y = -1x + 2
Put the points in the slope equation to find (-1 as m, -2 as x, and 4 as y)
y = mx + b
4 = -1(-2) + b
4 = 2 + b
4 - 2 = b
2 = b
Final equation: y = -1x + 2
Answer:
the third one
Step-by-step explanation:
because it cant be the 2nd or 4th one theyre both facing the other way
