Identify the variation as direct, inverse, joint or combined. s=c/t^3

Inverse

Step-by-step explanation:

Assuming that c is a constant (the constant of proportion), s = c / (t^3) is a case of inverse variation:  As t increases, s decreases.

if x decreases by 4 then y increases by 10

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
