1) graphs y = -9x + 12 and y = 1/3x - 12 are not coincident.
2) The graphs are not parallel, because the angular coefficients are not equal
3) The condition of perpendicularity:
, where 
- not perpendicular
R = x(a + b)
r = ax + bx
r - ax = bx
r - ax/x = b
b = r - ax/ x
Answer:
you suck go do your test yourself
Step-by-step explanation:
keep coping idiot
The function that models the scenario is
v = init_v + acceleration * time
Plug the values into the equation,
0 = 28 + a * 7 => -28 = a * 7 => a = - 28/7 m/s.
Answer:
$3.50
Step-by-step explanation:
add up all the x's and distribute them starting from the outside until you get to the middle. if there is an odd number of x's (which there isn't), the last x to be placed will be on the spot that is the median. If there is an even number of x's, and they both land on the same spot, that spot will be the median, and if they are next to each other, the median will be between them.
