The GCF of 15 and 35 is 5
Answer:
Average speed of the two boats are 28 km/hr. and 24 km/hr.
Step-by-step explanation:
Let the average speed of the boat with larger speed is x km/h and that of the other boat is y km/h.
Now, given that x - y = 4 ...... (1)
If the distance, that the first boat covers in 3 hrs. is d km then the second boat covers d km in 3.5 hrs.
Therefore, and
Now, from equation (1), we can get
⇒
⇒ km/hr.
Again, km/hr.
Therefore, the average speed of the two boats is 28 km/hr. and 24 km/hr. (Answer)
Y = 1/2x + 6
slope here is 1/2. A parallel line will have the same slope.
y = mx + b
slope(m) = 1/2
(0,-2)...x = 0 and y = -2
now sub and find b, the y int
-2 = 1/2(0) + b
-2 = b
so ur parallel equation is : y = 1/2x - 2
