<h3>
Answer: Choice A</h3>
center = (3, -1)
radius = 3
==================================================
Explanation:
Rewrite the y+1 as y-(-1). Rewrite the 9 as 3^2
Then compare to the general form (x-h)^2+(y-k)^2 = r^2
You should find that h = 3, k = -1 and r = 3.
The center is (h, k) = (3,-1) and the radius is r = 3.
Choice A matches with that description.
Answer:
x = 1
Step-by-step explanation:
We know that the two angles must be equal to each other. So:
65x - 12 = 43x + 10
First add 12 to both sides:
65x - 12 + 12 = 43x + 10 + 12
65x = 43x + 22
Then subtract 43x from both sides:
65x - 43x = 43x - 43x + 22
22x = 22
x = 1
School A : 12/45 = 0.266 = 26.6%
school B : 15/40 = 0.375 = 37.5%
school C : 9/27 = 0.333 = 33.3%
school D : 13/32 = 0.406 = 40.6%
so ur answer is school D
Answer:
5 4/9
Step-by-step explanation:
