Here is a circle with a radius of 15 units whose center is at (0,0).

1. If the y-coordinate of point C is 12, what is the r-coordinate?

Explain or show your reasoning.

2. Name 2 other points that must be on the circle.

Janie has $3. she earns $1.20 for each chore she does and can do fractions of chores. she wants to earn enough money to buy a cd for $13.50. write an inequality to determine the number of chores, c, janie could do to have enough money to buy the cd.

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
