Apply the standard equation of a circle with center at (h,k) and radius r:
(x-h)^2 + (y-k)^2 = r^2
Using the given data,
(x-2)^2 + (y+4)^2 = 3^2
Answer:
Vertex is (5,-9)
Step-by-step explanation:
Answer:y=0 So its A
Step-by-step explanation:3(-y+7)=3(y+5)+6
We move all terms to the left:
3(-y+7)-(3(y+5)+6)=0
We add all the numbers together, and all the variables
3(-1y+7)-(3(y+5)+6)=0
We multiply parentheses
-3y-(3(y+5)+6)+21=0
We calculate terms in parentheses: -(3(y+5)+6), so:
3(y+5)+6
We multiply parentheses
3y+15+6
We add all the numbers together, and all the variables
3y+21
Back to the equation:
-(3y+21)
We get rid of parentheses
-3y-3y-21+21=0
We add all the numbers together, and all the variables
-6y=0
y=0/-6
y=0
Answer:
She goes from 4 to -4 west which is 8 blocks west
Then she goes south from +2 to -2 on the y axis which is 4 blocks south
