Lunch costs $2.25 per day. An equation showing the relationship between the number of days, d, and the total cost of lunch, c, is c = 2.25d What is
the dependent variable?*

d = the number of days
c = the total cost of lunch

What is the answer?

The dependent variable is c

Step-by-step explanation:

The cost of lunch changes with each day, so the cost depends on the number of days

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

c. side angle side. u shares the same sides
