Answer:

9

Step-by-step explanation:

the center of the circle is A(2,-2) , the radius is the distance from A( center to the circumference) is 3 points

(x-2)^2+(y+2)^2=r^2    r=3 so r^2=9

(x-2)^2+(y+2)^2=9

All real numbers greater than or equal to -8. You can see 3 is a minimum point because at 3 the numbers start to increase again. -8 is the lowest number and the function is increasing as x approaches infinity starting at 3.

1) Answer: 21
As y varies directly with x, this means that the ratio y/x is always a constant.
In other words, the equation can be written as y = kx, where k is a constant term.

Thus, -\frac{14}{4} = -\frac{y}{6}
y = 21

2) Answer: C
Exactly the same process as above.
Here's another method:
25 = k(140)
k = 25/140 = 5/28

Thus, when y = 36, 36 = kx
36 = 5/28(x)
36 * 28/5 = x; x = 201.6

3) 9 = k(12)
9/12 = k and k = 3/4

4) On the graph, it hits y = 1 at x = 4.
Thus, we can rewrite the equation as:
y = (1/4)x, where the constant term is 1/4

5) y = kx
The distance represents the x-ordinates, and the time represents the y-ordinates.

9.5/475 = 0.02
4 = 0.02(x), in hours.
x = 200 miles.
