Step-by-step explanation:
So the Ap will be x,x+10,x+20,x+30
Sum of the angles of a quadrilateral is 360
x+x+10+x+20+x+30=360
4x+60=360
4x=300
x=75
So the angles are 75,85,95,105
Answer:
From (0,0) and (2,3) the slope is 2/3.
Step-by-step explanation:
Answer:
That is so easyyyyyyyyy
Step-by-step explanation:
Answer: 4.F(x) > 0 over the intervals (-0.7, 0.76) and (0.76, ∞).
Hope this helps :)
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)
