Q9: identify the graph of the equation and write an equation of the translated or rotated graph in general form. (picture provided below)

D. Circle; (x²) + (y²)-4=0

Step-by-step explanation

Simplify the equation by dividing both sides by 2

2x² + 2y² =8

x² + y² =4

this gives a circle form where we can apply (x-h) ² +(y-k)² =r² to find center and radius of the circle.

Thus r=2, h=0, k=0

Center of circle is at (h, k), (0,0)

Radius of circle is 2

its electric no smoke

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
