first put both options into equation format. option 1: 360+75m and option 2: 24(30). solve the easier problem first which is 24 multiplied by 30 which equals 720. so now you know what should be on the side of the equal sign so that they both have eqaul solutions. 360+75m =720. subtract 360 from both sides so that equation turns to 75m=360, then divide both sides by 75 and get 4.8. it would take 4.8 months

The equation of a circle is (x – 3)2 +(+8)2 = 36. Relative to the standard equation of a circle (zº+y? = r?), how has

Zolol [24]

Answer:

A. The circle has been shifted 3 units to the right and 8 units down, r=6

Step-by-step explanation:

Recall that the equation of a circle is $(x-h)^2+(y-k)^2=r^2$ where $(h,k)$ is the center of the circle and $r$ is the radius.

Given that the equation is $(x-3)^2+(y+8)^2=36$ , this tells us that the center of the circle is at $(h,k)\rightarrow(3,-8)$ and the radius is $r=6$ . Since the value of $h$ represents the amount of horizontal shift from the origin and $k$ represents the amount of vertical shift from the origin, then the circle was shifted 3 units to the right and 8 units down.
