Answer:
10
Step-by-step explanation:
The first equation should be the same with the second one, then we will have an infinite number of solutions of this system.
So if I multiply the first equation by 3, it'll be
6x-18y=3k
So if they should be the same, 30=3k
K=10
28.7% rounding off would be 29%
Answer: The vector represents its new position is (10,25)
Step-by-step explanation:
A bird starts from the ground, that is (0,0) position and flies at a certain speed for 5 seconds, and lands on a tree branch.The vector representing its position is (4,10).
The rate of increase = slope will be
Slope = 10/4 = 2.5
It continues to fly in the same direction and at the same speed for 5 or more seconds
Since it is travelling at same speed and time, Slope will be the same
Slope = (y - 10)/(x - 4) = 5/2
The new x position = 4 × 5/2 = 10
The new y position = 10 × 5/2 = 25
The vector represents its new position is (10 , 25)
Answer:
1
Step-by-step explanation:
You must divide the 7 from all parts of the equation, not only from the y.
