I can help you round 206834 and 194268 to its nearest thousands place. 207000 would be the estimate for the first number and 194000 would be the estimate for the second number.
Answer:
Step-by-step explanation:
We have been given the function 
Below are steps for finding the inverse of the function.
Step 1:
Replace f(x) with y
Step 2:
Interchange x and y
Step 3:
Solve for y
Step 4:
Replace y with 
X^2 + y^2 - 2x + 7y + 1 = 0
(x^2 - 2x) + (y^2 + 7y) + 1 = 0
(x^2 - 2x + 1) + (y^2 + 7y) + 1 = 0+1
(x^2 - 2x + 1) + (y^2 + 7y + 49/4) + 1 = 0+1+49/4
(x - 1)^2 + (y + 7/2)^2 + 1 = 0+1+49/4
(x - 1)^2 + (y + 7/2)^2 + 1-1 = 0+1+49/4-1
(x - 1)^2 + (y + 7/2)^2 = 49/4
(x - 1)^2 + (y + 7/2)^2 = (7/2)^2
The final answer is choice B
Answer:
- 9z^2
Step-by-step explanation:
Since the negative sign is outside of the parentheses it is not raised to the power of 2
- ( 3z) ^2
- ( 3z) * (3z)
- 9z^2
