Answer:

Center: (0, 0)

Radius: 4

Step-by-step explanation:

Circle Standard Equation: (x - h)² + (y - k)² = r²

(h, k) is center

r is radius

We see that our <em>h</em> and our <em>k</em> are both 0.

∴ Our center is (0, 0), origin.

We see that our r² = 16

√r² = √16

∴ Our radius is equal to 4

Is x+3=-5y in standard form?

skad [1K]

Answer:

Nope

Step-by-step explanation:

Standard form for a linear equation in two variables is $Ax+By=C$ with the terms containing x and y on the left side of the equation and a number on the right side.

$x+3=-5y$

Subtract 3 from both sides.

$x=-5y-3$

Add 5y.

$x+5y=-3$
