Answer:
k = - 
Step-by-step explanation:
Given that x varies directly with y then the equation relating them is
x = ky ← k is the constant of variation
To find k use the condition x = - 3 when y = 12
- 3 = 12k ( divide both sides by 12 )
= k , that is
k = -
Answer:
This is probably wrong. But i hope this helps anyways
Step-by-step explanation:
If the perimeter is twice its width, and the perimeter is 60. That means the whole length of the shape youre looking at is 120. (60•2) we can assume that this shape has 4 sides. 60/4. Thats 15. So the sides are 4 ft. The length is at the top and bottom is 15. 15•4 = 60. There ya go
Answer:
Substitute the value of the variable into the equation and simplify.

Answer:
-1/5
Step-by-step explanation:
Slope of the line = (y2-y1)/(x2-x1)
(2-(-8)/(5-3)
10/2 = 5
Perpendicular line = the slope is opposite of the reciprocal
-1/5
