Step-by-step explanation: basic math
Answer:
(1,3)
Step-by-step explanation:
y = 2x+1
y = 4x-1
Since both equations are equal to y, we can set them equal to each other
2x+1 = 4x-1
Subtract 2x from each side
2x+1-2x = 4x-2x-1
1 = 2x-1
Add 1 to each side
1+1 = 2x-1+1
2 = 2x
Divide each side by 2
2/2 = 2x/2
1 =x
Now we need to find y
y = 2x+1
y = 2(1)+1
y =3

Answer:
Co-ordinate of the center is (3, -4) and radius is 5
Step-by-step explanation:
x2 - 2.3x + 9 + y2 +2.4y +16 = 16 + 9
(x-3)2 + (y+4)2 = 25
Co-ordinate of the center is (3, -4) and radius is 5
