A bakery charges $10 for a plate of cookie, plus $2 for each additional cookie. Write an equation to model the total cost y of purchasing x cookies.

y=10+2x

Step-by-step explanation: I just finished this unit in Algebra today. :) Since y is our variable for the total cost, that goes on one side of the equal sign. A plate of cookies is $10 to start off with, and an additional cookie is $2. What if you want 5 extra cookies? Maybe even 6? Attach the variable x. Your final equation is y=10+2x. Hope this helped!

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

the 3rd on is correct
