BEST ANSWER GETS TO BE BRAINLYEST!!!!!
Lera25 [3.4K]
Hey there!

"9 pounds more than" means that you'll be adding 9 to the expression. 

"half the weight w" means that you'll be calculating half of w each time you solve the equation, or 0.5w. 

Your entire expression will be 0.5w + 9. 

Hope this helped you out! :-)

Which is the equation of a circle with its center at (-4,2) and a radius of 4?
Snowcat [4.5K]

Answer:

(x +4)^2 + (y-2)^2 = 16

Step-by-step explanation:

We can write the equation for a circle with the formula

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

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

We know the center is at (-4,2) and the radius is 4

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

(x +4)^2 + (y-2)^2 = 16
