The equation of the circle is written as (x-h)² + (y-k)² = r²
With the given center and radius the equation will be
(x + 2)² + (y + 3)² = 16
The answer is A
Hope this helps :)
Answer:
i think the answer is A... i'm not suree tho
Answer:
m-9=42
Step-by-step explanation:
An amount subtracted by $9 is $42.
(an amount is unknown, so it is represented with variable, m)
m-9=42
EXTERNA ANGLE TO A CIRCLE:
mes Angle 55° = mes ARC (x°) - mes ARC 40°
55=x-40 ==> x = 95°
Answer:
225
Step-by-step explanation:
Mary = 3x (3 times Carey)
Carey = x
Barry = x/2 (Because Carey read twice as many as Barry, it means he read half the amount Carey did)
3x + x + x/2 = 405
4x + x/2 = 405
8x/2 + x/2 (treat these as fractions) = 405
9x/2 = 405
9x = 810 (cross multiply)
x = 90
Mary = 3(90) 270
Carey = 90
Barry = 90/2 45
Mary - Barry
270 - 45 = 225
Hope this helps! :)
