Answer:
Mirandah added 5x and 9y, which she shouldn't do because one is y and the other is x, meaning they don't match.
There is no simplifying the equation. It should stay 5x + 9y - 4
If wrong, I apologize, but this should be correct.
Vertex formula = -b/2a
-18/1 = 18.
However, this is just the x value, the vertex is (x,y)
-18*2 + 18(18) - 72 = 576
A) (18,576)
576 dollars made with 18 members is the highest amount made in one day.
B) (12,0) (6,0)
Answer:
∠ O = 72°
Step-by-step explanation:
the inscribed angle R is half the measure of its intercepted arc NQ , then
arc NQ = 2 × 36° = 72°
the central angle O is equal to the measure of the arc that subtends it , so
∠ O = arc NQ = 72°
