Answer:

Step-by-step explanation:

hello : Completing The Square

X²+y²-10x-16y+53=0 means : (x²-10x+25-25)+(y²-16y+16-16)+53 =0

(x²-10x+25)-25)+(y²-16y+64)-64+53 =0

(x+5)²+(y-8)² -25-64+53=0

(x+5)²+(y-4)² = 6² standard form

the center is (-5 , 4) and the radius : 6

Answer:

equation of circle is (x+5)^2+(y-3)^2=16

Step-by-step explanation:

equation of circle $(x-x_1)^2+(y-y_1)^2=r^2where r=redius of circle,[tex](x_1,y_1)$ is centre of circle

centre of circle=(-5,3)

put the value of centre and redius in the equation

Please help me with this math question

Leona [35]

Answer:

X + Y - W - Z = 180

Step-by-step explanation:

In parallel lines If you use the rules of:

* Alternate angles are equal

* Linear Pair Angles supplement to 180

And use the picture below for calculating the result: finally we get

Z = Y - (180 - (X - W)) which becomes the answer above if you simplify the parentheses.

Which equation is equivalent to<br> 5 - 2x = 4?

expeople1 [14]

-2x = -1
x = 1/2
Any equation that returns x=1/2 is a solution to this problem. For example, x= (3•4)/6 can be simplified so that x=1/2

Hi there,

The percentage of 3/5 would be %60
