Answer:
Option A: Madison, (1.2,-1.6) is the correct answer.
Step-by-step explanation:
Observing Madison's solution it can be seen that he has used elimination method to solve the system. If elimination method has to be used the first equation has to be multiplied by 4
While Madison has made mistake with sign of one term in equation 1 (he has written -8x instead of 8x)
So <u>Madison's solution is wrong. </u>
Tyler has used the substitution method to solve the system of equations and has done it correctly (Calculated value of y in terms of x from equation 1 and substituted in equation 2)
The value of x=1.2 is correct, we have to find the value of y
So,
Putting the value of x=1.2 we get,
The solution of given system of equations is (1.2,-1.6)
Hence,
Option A: Madison, (1.2,-1.6) is the correct answer.
Ok so for Letter F the answer is going to be x=2 or y=-2 depending if you’re trying to find x or y.
Hey there! I'm happy to help!
2 minutes is 120 seconds, and we add 2.24 seconds giving us a total time of 122.24 seconds.
We have 300 meters every 122.24 seconds. To find out how far he ran every one second, we divide by 122.24.
300/122.24=2.45188482....
We round to the nearest hundredth, giving us a speed of 2.45 meters per second.
Have a wonderful day! :D
