Can someone with 40 and 41? i'm using all my points

40.  x^2 +(y+3)^2 = 7^2

41. (x+2)^2 +(y-5)^2 = 4^2

Step-by-step explanation:

The equation for a circle is

(x-h) ^2 + (y-k)^2 = r^2

where (h,k) is the center  and r is the radius

40.  center (0,-3)  and radius =7

(x-0)^2 +(y--3)^2 = 7^2

x^2 +(y+3)^2 = 7^2

41.  center (-2,5)  and radius =4

(x--2)^2 +(y-5)^2 = 4^2

(x+2)^2 +(y-5)^2 = 4^2

answer: what equations are there

step-by-step explanation:

b.an increase in a causes b to decrease
