Answer:

the center is : (2 , - 5) and radius 5

Step-by-step explanation:

hello :

x² + y² – 4x + 10y + 4 = 0

(x²-4x)+(y²+10y)+4 =0

Completing The Square :

(x²-4x+4)-4+(y²+10y+25)-25+4 =0

(x-2)²+(y+5)²= 5² .....standard form

the center is : (2 , - 5) and radius 5

Find an ordered pair to represent a in the equation<br> a=2b+c if b=(6,3) and c=(-4,8)

zaharov [31]

Answer:

The ordered pair to represent a in the equation a=2b+c if b=(6,3) and c=(-4,8) is: a=(8,14)

Step-by-step explanation:

b=(6,3)

c=(-4,8)

a=2b+c

Replacing b and c in the equation above:

a=2(6,3)+(-4,8)

Multiplying:

a=(2*6,2*3)+(-4,8)

a=(12,6)+(-4,8)

Adding:

a=(12+(-4),6+8)

a=(12-4,14)

a=(8,14)
