Answer:
-11
Step-by-step explanation:
m + n = - 2
4(m + n) = - 2(4) (multiplying both sides by 4)
4m + 4n = - 8
4m + 4n - 3 = - 8 - 3 (Subtracting 3 from both sides)
4m + 4n - 3 = - 11

The vector sum of two vectors as (7,5) and (13,-5) is given by 
which can be written in point form as (20,0) .
<u>Step-by-step explanation:</u>
Here we have , two vectors as (7,5) and (13,-5) Which are represented as :
Addition of vector is as same as normal addition of integers as :
⇒ 
⇒ 
⇒ ,
where i & j are the unit vectors in direction x-axis and y-axis respectively.
The vector sum of two vectors as (7,5) and (13,-5) is given by which can be written in point form as (20,0) .
Answer: C. Reasonable. The estimate sooms a little higher compared to the actual answer
Step-by-step explanation:
The actual answer to 359+558 is 917. On the other hand, 359 to the nearest ten is 360 while 558 to the nearest ten is 560. The addition of the numbers will be: = 360 + 560 = 920
The estimated answer is 920 while the actual number is 917. Therefore, the estimate is reasonable as the estimate sooms a little higher compared to the actual answer.
