We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0
y^2-3y=0
y(y-3)=0
y1=0 -----------y2=3
Answer:
Total cycling time = 5 hrs + 19 mins + 18 secs
Step-by-step explanation:
i). Shortest distance cycled = 15.05 miles
ii). Longest time cycled for = 2:09:12 hrs : mins: secs
iii). Time taken by David on 28/04/2018 = 1 hrs + 3 minutes + 25 secs
Time taken by David on 03/05/2018 = 2 hrs + 6 minutes + 41 secs
Time taken by David on 08/05/2018 = 2 hrs + 9 minutes + 12 secs
Total cycling time = (1 + 2 + 2) hrs : (3 + 6 + 9) minutes + (25 + 41 + 12) secs
= 5 hrs + 18 mins + 78 secs
Since, 78 seconds = 60 secs + 18 secs
= 1 minute + 18 secs
Therefore, total cycling time = 5 hrs + 19 mins + 18 secs
Answer:
Step-by-step explanation:
This is more easily understood if you take out a common factor of -1
-1(x^2 + 15x + 56)
7*8 = 56
7 + 8 = 56
-1 (x +8)(x+7)
Answer:
well let's see below.
Step-by-step explanation:
If you're simplifying the fractional form, the answer would be f(x) + x/2 =4.
