The correct answer is A, it has -1. While B's got 1.
Answer:
(x + 5)² + (y - 7)² = 13
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
Here (h, k) = (- 5, 7) and r = 
, thus
(x - (- 5))² + (y - 7)² = ( )² , that is
(x + 5)² + (y - 7)² = 13 ← equation of circle
4396.6 bc the different between the years was 22 and 2060 thousand people and that divided is 93.6 and 3835 +93.6(6) is 4396.6 bc the 6 you multiply by is from the difference of 1998 and 1992
NUMBER 3 :
150 feet / 15 = 10 units
120 feet / 15 = 8 units
So it will be 10 units by 8 units
NUMBER 4:
A) 525/4.2 = 120
The scale used was 120
B) 0.6 inches = 0.0152
525 / 0.0152 = 35 sheets tall
Answer:
y = -2x
Step-by-step explanation:
A "direct variation" relationship has the form y = kx, where k is the "constant of proportionality.
Note that this graph goes thru the origin (which it must, to represent direct variation), and that it has a steep negative slope. That narrows down the answer choice to the first one: y = -2x.
