Answer:
1. 6
2. 5
3. 3
4. 7
5. (x-4)2 + (y+3)2 =25
6. x2+ y2 = 36
7. (x-3)2+(y-3)2 = 4
8. x2 + (y+2)2 = 81
Step-by-step explanation:
use formula (x-h)2 + (y-k)2 = r2
where (h,k) is center and r is radius
Answer:
The least common denominator is (b-8)(b+8)(b-1)
Step-by-step explanation:
We are given expression as

Firstly, we will factor both denominators


so, we can plug it back

First term denominator is
(b-8)(b+8)
Second term denominator is
(b+8)(b-1)
So,
Least common denominator will be
(b-8)(b+8)(b-1)
So, we get

Answer:
When x = 64, y = 80.
Step-by-step explanation:
Since the origanal value was 8 and now it´s 64, lets divide to see how much was multiplied. Then lets multipliy it with that number.
64 / 8 = 8
Soo..8 x 10 = 80.
When x = 64, y = 80.
Answer:
s = 15
Step-by-step explanation:
We know that a straight line measures 180°
so… in order to find the value of s add the two angles with a sum of 180 and then solve for s
(9s + 8)° + 37° = 180°
Combine like terms
9s + 45 = 180
Subtract 45 from both sides
9s = 135
Solve for s
s = 135/9
s = 15
