We have:
Answer:The center: (-2; 4)The radius: r = 4
Answer:
9
Step-by-step explanation:
When plugging 6 in for y, you get
2x + 3(6) = 36
You have to multiply 3 and 6, getting
2x + 18 = 36.
Now, you subtract 18 from both sides to isolate the x variable, getting
2x = 18
Now, you divide 2 from both sides because we want x standing by itself, getting
x = 9
Therefore, your answer is 9.

Answer:
70°
Step-by-step explanation:
A+B+C=180°
70°+40°+C=180°
C=180°-110°
C=70°
Just plug in 3 for n and then 5 for n to see if an turns out to be 10 and 26.
n=3:
A) an = 8*3+10 = 34
B) an = 8*3 - 14 = 10 OK
C) an = 16*3+10 = 58
D) an = 16*3 - 38 = 10 OK
n=5:
B) an = 8*5-14 = 26 OK
D) an = 16*5 - 38 = 42
So the answer is B
