Answer: -3
Step-by-step explanation: well there is a pretty easy explanation for this because what you pretty much do is you put the answer around by doing 5-2 and just put a negative since the smaller number is in the front.
Answer:
The system of equations has a one unique solution
Step-by-step explanation:
To quickly determine the number of solutions of a linear system of equations, we need to express each of the equations in slope-intercept form, so we can compare their slopes, and decide:
1) if they intersect at a unique point (when the slopes are different) thus giving a one solution, or
2) if the slopes have the exact same value giving parallel lines (with no intersections, and the y-intercept is different so there is no solution), or
3) if there is an infinite number of solutions (both lines are exactly the same, that is same slope and same y-intercept)
So we write them in slope -intercept form:
First equation:

second equation:

So we see that their slopes are different (for the first one slope = -6, and for the second one slope= -3/2) and then the lines must intercept in a one unique point. Therefore the system of equations has a one unique solution.
56.7 mph just a distance over time question, since they want the average speed you take the total distance divided by the total time
Answer:
La abscisa x del centro de masa está en reposo (velocidades opuestas)
Vx = 0
La ordenada del centro de masa es:
y = h + Vo sen(α) t + Vo sen(α) t = h + 2 Vo sen(α) t
La velocidad es la derivada de y respecto del tiempo:
Vy = 2 Vo sen(α)
b) Momento lineal (p = m V)
En el eje x: px = 0 (momento lineal)
En el eje y: py = 2 m Vy = 4 m Vo sen(α)
