2. T-T-T-H 6. T-H-T-H 10. H-T-T-H 14. H-H-T-H
3. T-T-H-T 7. T-H-H-T 11. H-T-H-T 15. H-H-H-T
4. T-T-H-H 8. T-H-H-H 12. H-T-H-H 16. H-H-H-H
Tails = T Heads = H

If (7, m) is on a circle with center C(−2, 2) and radius 9, what is the value of m?

Answers

First thing I did was check the distance between the point and the center of the circle on the x-axis, because that was the information already given. Turns out that 7 - (-2) = 9, and so m is equal to the y-value of the center of the circle.

m = 2

Hope that helps!

Solve for all values of b in simplest form. 13=|2b+12|

Answers

Answer:

b = 1/2, -12.5

Step-by-step explanation:

13 = |2b+12|

Case 1:

13 = |2b+12|

13 = 2b + 12

1 = 2b

b = 1/2

Case 2:

13 = |2b+12|

13 = - (2b + 12)

13 = -2b - 12

25 = -2b

b = -12.5

So, the answer is b = 1/2 & -12.5
