Dianne's profit from selling magazine subscriptions varies directly with the number of subscriptions sold. dianne made $30 from selling 24 subscriptions. which equation relates dianne's profit (y) to the number of subscriptions she sold (x)? a) y = 4 5 x b) y = 1.25x eliminate c) y = 5 4x d) x = 20xy

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
