To answer the question above, we let s be the cost of a shirt and h be the cost of each hat such that the equations that would best represent the given are:
10s + 20h = 490
20s + 30h = 860
The system of equations is the answer to the first question and the values of s and h are $25 and $12, respectively.
Step-by-step explanation:
the y coordinate is always the second value. for example, if u have (3,2) the y value is 2
B) m= 1/2
you would use slope formula to find what line passes through those coordinates
Answer:
(7, -2)
Step-by-step explanation:
Add the points together and divide them by 2:
A+B/2
= ([7 + 7]/2, [3 + -7]/2)
= ([14]/2, [-4]/2)
= (7, -2)
Answer:
3) directly above the package.
Step-by-step explanation:
The plane and the package carried by the plane are traveling with the same horizontal speed. When the package is dropped, a new vertical component of velocity is added to the package. The vertical velocity increases because of the acceleration due to gravity. The horizontal speed of the package remains the same. As long as the plane continues to fly at the same speed, the package hits the ground directly below the plane.
Answer: 3) directly above the package.
