Answer:
(x+8)² + (y+13)² = 169
Step-by-step explanation:
Equation of circle:
(x-h)² + (y-k)² = r²
(h,k) is the centre, r is the radius
(x-(-8))² + (y-(-13))² = 13²
(x+8)² + (y+13)² = 169
Answer:
y=35
Step-by-step explanation:
10(y+7)=12y
10y+70=12y
70=12y-10y
70=2y
70/2=y
35=y
therefore, y=35

Answer:
$90
Step-by-step explanation:
You pay $20 the first day, then subtract $2 each day. Add the numbers up to get the total. 20+(20-2)18+(18-2)16+(16-2)14+(14-2)12+(12-2)10=90
Answer: $90
Answer:
Option C. 19 blocks
Step-by-step explanation:
From the given graph we can calculate the distances between Zaley to Amanda and Zaley to Karen in blocks so that we can apply Pythagoras Theorem in the given right angle triangle to calculate the distance between Karen and Zaley.
Distance between Amanda and Karen = 6 blocks
Distance between Amanda and Zaley = 5 blocks
Then distance between Karen and Zaley = √5²+6² = √25+36 = √61 = 7.8 ≅ 8 blocks.
Therefore Zaley travels the distance from her house to Amanda, Karen and back to her house will be = 5 + 6 + 8 = 19 blocks
So the answer is Option C. 19 blocks
