Answer:
(-a-b,c)
Step-by-step explanation:
midpoint D : ((-2b-2a)/2 ;(2c+0) /2 )
(-2b-2a)/2 = 2(-b -a)/2 = -b-a
(2c+0) /2 =2c/2 = c
Answer:
k = 4
Step-by-step explanation:
if direct variation exists,
input * k = output
here, number of baskets = input and cost = output
3 * k = 12
5 * k = 20
6 * k = 24
8 * k = 32
15 * k = 60
does this always work for one k?
let's try it out
3 * k = 12
divide both sides by 3 to solve for k
k = 4
5 * k = 20
divide both sides by 5 to solve for k
k = 4
6 * k = 24
divide both sides by 6 to solve for k
k = 4
8 * k = 32
divide both sides by 8 to solve for k
k = 4
15 * k = 60
divide both sides by 15 to solve for k
k = 4
as k = 4 no matter what, there is a direct variation with k = 4
