I need help with this question and please don't answer it just to get points

1,500

Step-by-step explanation:

Remember that in a cost function, the cost per item is multiplied by x and the fixed cost is the part of the equation that is not multiplied by anything.

Cost = (Cost per item)(x) + Fixed cost

C(x) = 90x + 1,500

As you can see:

(Cost per item) would be 90

x would be, well x.

The fixed cost would be 1,500.

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.

the answer is y = 11.54

hope this : )
