Step-by-step explanation:
If "u" varies directly with "v", and u = 6 when v = -7, what is "u" when v =4?

Answer:
u = -
Step-by-step explanation:
Given that u varies directly with v then the equation relating them is
u = kv ← k is the constant of variation
To find k use the condition u = 6 when v = - 7, then
6 = - 7k ( divide both sides by - 7 )
- = k
u = - v ← equation of variation
When v = 4 , then
u = - × 4 = -

Answer:
Midpoint = (3.5, 4.5)
Perpendicular bisector = y = x +
Step-by-step explanation:
[] We can solve this using the midpoint formula:
-> See attached
[] Plug-in our coordinates and solve:
[] Now we will find the slope to solve for the perpendicular bisector.
-> We will use slope-intercept form, see attached
-> The slopes of two perpendicular lines are negative reciprocals of each other, so will be the slope of or perpendicular bisector
-> Now we can solve for the equation by using y – y1 = m ( x – x1), were y1 and x1 are the coordinates of our midpoint
y - 4.5 = (x-3.5)
y - 4.5 = x-
y = x-
+ 4.5
y = x +
