frosja888 [35]

Answer:

1. y=5-2x

2. -y=5-2x

3. $\frac{5 - x}{2}$

Step-by-step explanation:

1. 2x+y=5

y=5-2x

2. 2x-y=5

-y=5-2x

3. x+2y=5

2y=5-x

$\frac{5 - x}{2}$

A 500 g model train car traveling at 0.8 m/s collides with a 300 g stationary car. The cars hook up and move off down the track

sdas [7]

Answer:

$0.5ms^{-1}$

Step-by-step explanation:

Let v be the speed after the collision of both the cars.

Now, momentum is given by: mass × velocity, then by equating the total momentum before and after the collision of the two cars, we get

$500{\times}0.8+300{\times}0=(500+300)v$

⇒ $400+0=800v$

⇒ $400=800v$

⇒ $v=0.5ms^{-1}$

Thus, they are moving at the velocity of $0.5ms^{-1}$

20. What is the order of rotational symmetry for each design (i.e. what is the angle of rotation to create

Minchanka [31]

Your answer should be:

<em>The order of rotational symmetry of a regular polygon is the same as the number of sides of the polygon. You can also deduce the order of rotational symmetry by knowing the smallest angle you can rotate the shape through to look the same. 180° = order 2, 120° = order 3, 90° = order 4. </em>

<em>I hope this helped :) </em>
