Answer:
They traveling at 
in backward direction.
Step-by-step explanation:
Given mass of Ammy 
and velocity is forward at 
Also, mass of Jenny 
Who is travelling in opposite direction 
Let velocity in forward direction is positive and velocity in backward direction is negative.
Also, velocity after crash is 
As they crashed into each other and they moved as one mass. We can apply principle of conservation of momentum.
Conservation of momentum says momentum before collision should equal to momentum after collision.
So, velocity after collision ≅
is in opposite direction. That is the direction of Jenny.
Answer: 10
Step-by-step explanation:
So the “certain number” will be S.
Since 2width + 2length, the first part would be 2 times 2 which is 4
The length is S - 3
We then have to multiply this by 2
So it is 2(S-3) which is 2S-6
So the answer is 4+2S-6 which is 2S-2
Answer:
the y-coordinate will be at (0, 2.4)
the x-coordinate will be at (6, 0)
Step-by-step explanation:
y coordinate of the graph is the point where the curve cuts the y axis
According to the graph, the curve cuts the y axis at y = 2.4. Hence the y-coordinate will be at (0, 2.4)
Similarly, the x-coordinate of the graph is the point where the curve cuts the x-axis
According to the graph, the curve cuts the x-axis at x = 6. Hence the x-coordinate will be at (6, 0)
A = 6b
a - b = 35
6b - b = 35
5b = 35
b = 35/5
b = 7
a = 6b
a = 6(7)
a = 42
ur numbers are 7 and 42
