Answer:
A
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 9)² + (y - 6)² = 10² is in this form
with centre = (- 9, 6) → A
Ok so 9x minus 11x you get -2x then the two y^2 cancel each other out to get -2x if the y^2 is separate from the x variable. However if its all one then it would be just 9 minus 11 to get -2 then putting the variable back on the end to get -2xy^2.
Answer:
ITS C STRAIGHT LINE ACROSS
Step-by-step explanation:
We can add in any order. So 5x+y is the same as y+5x
5x+y = 10
y+5x = 10
y+5x-5x = 10-5x ... subtract 5x from both sides
y+0x = -5x+10
y+0 = -5x+10
y = -5x+10
Answer: y = -5x+10
Note: this is in y=mx+b form where m = -5 is the slope and b = 10 is the y intercept
