Answer:
The answer to your question is Center = (-8, 6) radius = 7
Step-by-step explanation:
Data
(x + 8)² + (y - 6)² = 49
Center = ?
radius = ?
Process
1.- Write the standard form of a circle
(x - h)² + (y - k)² = r²
2.- Compare the equation given with the standard form
The center of a circle = (h, k)
h = -8 k = 6 r² = 49
r = √49
r = 7
3.- Conclusion
Center = (-8, 6) radius = 7
Y= 3.4. If you divide 37.4 by 11 then y would equal 3.4. Check by multiplying 3.4 by 11
Answer:1262.5
Step-by-step explanation:
A=amount p=principal r=rate n=time in years
A=p(1+r/100)^n
A=1000(1+6/100)^4
A=1000(1+0.06)^4
A=1000(1.06)^4
A=1000×1.2625
A=1262.5
Assume that the numbers are X and Y;
The sum of the two numbers is:
X+Y=-12
Their difference is:
X-Y=84
We can present the number X as a funsction from Y, from any of the equation. Let do that from the first: X=-12-Y
Now, in order to have only one unknown we will write X in this form in the second equation:
(-12-Y)-Y=84
-12-Y-Y=84
-12-2Y=84
-12-84=2Y
-96=2Y
Y=-96/2=-48
X=-12-Y=-12-(-48)=-12+48=36
The answer is B
Hope that helps
