In a direct variation, y=18 when x=9. write a direct variation equation that shows the relationship between x and y

y = 2x

Step-by-step explanation:

since x and y vary directly then the equation is

y = kx ← k is the constant of variation

to find k use the given condition y = 18 when x = 9

k = = = 2, hence

y = 2x ← is the equation relating x and y

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
