The Answer is C, my good friend.
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -7 and b = -1 (Center at: A(-7,-1) )
r = AP.... P(8,7)
r² = (AP)²
r² = (8+7)² +(7+1)² =225+64=289 ...... so : r = 17
an equation of the circle that satisfies the stated conditions.
Center at </span></span>A(-7,-1), passing through P(8, 7) is :
(x+7)² +(y+1)² = 289
The point (-15,y ) <span>lies on this circle : (-15+7)² +(y+1)² = 289....(subsct : x= -15)
(y+1)² = 225
(y+1)² = 15²
y+1 = 15 or y+1 = -15
y = 14 or y = -16
you have two points : (-15,14) , (-15, -16)</span>
Answer:
100 CD's
Step-by-step explanation:
250-175 is 75. and if yu subtract 175 by 75, you get 100. so 100 CD's
Okay so if $2 for the first 10 pounds, divide 10 by 2 and you get 5. every time you add a pound its a dollar more. so i think the answer is 45.
Answer:
B, E
Step-by-step explanation:
Given expression
First, use the distributive property:
Use distributive property once more:
So, option E is correct.
Now,
Thus, option B is correct
