A sandwich store charges a $10 delivery fee, and $4.50 for each sandwich. a. What is the total cost (sandwiches and delivery charge) if an office orders 6 sandwiches?

b. What is the total cost for x sandwiches? Write an equation in slope intercept form.

c. Graph the total cost of sandwiches and delivery based on number of sandwiches ordered. Be sure to label your axes and scale them by labeling each gridline with a number. Please use a piece of graph paper or screen capture and edit digitally. You will upload a picture of your graph in the next question.

answer: 12

step-by-step explanation:

because yes

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

the linear relationship that represents a variation in direct proportion is the linear function that varies according to the numbers of its domain, for example the cost of producing x number of items can be represented in direct proportion by f (x) = mx + b, where m is the constant of proportionality, x the number of articles produced and b the fixed cost
