Answer:
Explanation has been given in the attachment.
Step-by-step explanation:
A/b *100
For example,
30/600.
30/600=0.05
0.05*100=5%
8 Is the unit rate. For 9/27
We are given the expression of the equation of a circle that is x2 + y2 + 14x + 2y + 14 = 0. Using ocmpleting the squares:
x2 + y2 + 14x + 2y + 14 = 0(x+7)^2 + (y+1) ^2 = -14 + 49 + 1(x+7)^2 + (y+1) ^2 = 36 center thus is at (-7,-1) and the radius is equal ot square root of 36 equal to 6.
Answer:
Step-by-step explanation:
1) 2y + 6x
2) 2y + 8x +2
