The answer is C.
When a positive and negative number are multipled or divided, the result is negative.
Answer:
what does that mean
Step-by-step explanation:
The 4 in 42,672 is 40,000
And the 4 in 37,426 is 400
The answer is 100
600 = 360 + 240
In unit circle, (x,y) = (cos(240), sin(240) ) = (-sqrt(3) / 2, -1/2)
Try this solution:
1. if to transform the given equation into the standard form:
x²+y²-4x+6y-3=0;
(x²-4x+4)+(y²+6y+9)-16=0;
(x-2)²+(y+3)²=4²
2. Using the standard form it is possible to find the coordinates of the centre of given circle: x=2; y= -3
answer: b) - (2;-3)
