Answer:
(x + 7)2 + (y + 1)2 = r2.
To get we use point (8, 7): (8 + 7)2 + (7 + 1)2 = r2, r2 = 225 + 64 = 289 = 172.
So, equation of circle: (x + 7)2 + (y + 1)2 = 289
Step-by-step explanation:
2 x 10^2 because 2 x 10^2 is 200 in standard form and 200 is greater than 1.
Answer:
26
Step-by-step explanation:
First, add all the numbers together
23 + 24 + 27 + 25 + 26 + 23 + 21+ 32 + 29 + 30= 260
Then divide by the number of terms there are, in this case 10
260/10= 26
Answer:
y = -2 x = 0
Step-by-step explanation:
1. 3x-4y = 8
2. 18-5y = 10
Multiply equation 1 by 6
3. 18x-24y = 48
Subtract equation 2 from equation 3
4. -19y = 38
y = 38/-19
y = -2
Sub y = -2 back into equation 1
3x-4(-2) = 8
3x + 8 = 8
3x = 0
x = 0/3
x = 0
