Answer:
x1=((2√3)/3)i
x2=-0.5
x3=-((2√3)/3)i
Step-by-step explanation:
Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7
<u>Answer:
</u>
The average speed that the club is assuming is 50 miles per hour
<u>Solution:
</u>
We know that Distance = Speed × Time.
Here it is given that distance is 325 miles and the time to cover 325 miles is
hours which is equal to
hours.
Now to find the average speed mile per hour we use the formula

By cancelling 325 by 13 we get 25
= 25 × 2
= 50 miles per hour
Thus the average speed that the club is assuming is 50 miles per hour.
