Put the equation is standard form x^2+y^2+16x-8y+76=0

-8, 4, 2

Step-by-step explanation:

x^2 + y^2 + 16x - 8y + 76 = 0

x^2 + y^2 + 16x - 8y = -76

x^2 + 16x + y^2 - 8y = -76

x^2 + 16x + ? + y^2 - 8y = -76 + ?

x^2 + 16x + 64 + y^2 - 8y = -76 + 64

(x + 8)^2 + y^2 - 8y = -12

(x + 8)^2 + y^2 - 8y + ? = -12 + ?

(x + 8)^2 + y^2 - 8y + 16 = -12 + 16

(x + 8)^2 + (y - 4)^2 = 4

(x + (-8))^2 + (y - 4)^2 = 2^2

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
