Can you help me with these two questions please !!!!

zubka84 [21]

Answer: $(x+2)^{2}+(y-4)^{2} =16$

and

$(x-6)^{2} +(y+4)^{2} =20$

Step-by-step explanation:

Equation for a Circle

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

h= -2 k= 4 r= 4

$(x+2)^{2}+(y-4)^{2} =16$

Part 2

Complete the Square

$x^{2} +y^{2} -12x+8y+32=0\\(x^{2}-12x+-)+(y^{2}+8y)=-32\\(x^{2} -12x+36)=(y^{2} +8y+16)=-32+36+16\\\\(x-6)^{2} +(y+4)^{2} =20$

What's the difference between 2x+2 and 2x+2=10?

Lapatulllka [165]

Answer:

Step-by-step explanation:

Given both expression

2x+2 and

2x+2=10

the difference inlvosves basically the subtraction of one expression from the other expression.

now before we perform the subtraction operation, let us do some preprocessing.

let us equate the first and second expression to zero

2x+2=0 and

2x+2-10=0

we can now subtract

(2x+2)-(2x+2-10)=0

open bracket

2x+2-2x-2+10=0

collect like terms

2x-2x+2-2+10=0

0+0+10=0

the answer is 10
