Answer:
C. Samir stopped and stretched for 5 minutes.
Step-by-step explanation:
We are given that,
Samir walked for 10 minutes, then stopped and stretched for 5 minutes, walked again for 20 minutes and ran for another 15 minutes
As, we can see that for the parts where Samir is walking or running, he is not in a constant or still state i.e. his position is changing.
But, during the stretching time, he is still at that position and his position is not changing.
Thus, the linear constant part of Samir's journey is represented by the time he stopped and stretched for 5 minutes.
Plugging -6 in for x, we get -2sqrt(-6-7+1)=sqrt(something negative) which is clearly not possible.
Plugging -6 in for f(x), we get -6=-2sqrt(x-7+1) and 3=sqrt(x-7+1). Squaring both sides, we get 9=x-7+1 and by adding both sides by 6 we get 15=x, therefore having (15,-6) and proving that -6 is in the range, but not the domain (B)
Answer:x=53/6 and y=-55/6
Step-by-step explanation:
Let the first number x
Second number b y
Sum of the numbers x+y=-1/3
x-y=18
Solve simultaneously
Using elimination method
We get
2y=-55/3
y=-55/6
Substitute for y in equation 1
x+55/6=18
x=18-55/6
x=53/6
