A circle centered at the origin contains the point (0, -9). Does (8,"") also lie on the circle? Explain.

O No, the distance from the center to the point

same as
гааIUS.
(8 ) is not the same as the radius.
No, the radius of 10 units is different from the
distance from the center to the point
17.
(8,"")
0 Yes, the distance from the origin to the point
(8, V1?) is 9 units.
O Yes, the distance from the point (0, -9) to the point
(8, V1?) is 9 units

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.
