Answer:
(x + 1)² + (y - 1)² = 16
Step-by-step explanation:
Since the standard form for an equation of a circle is
<h3>
(x - h)² + (y - k)² = r²</h3>
The (h,k) are co-ordinate of your centre of circle, which in this case is (-1,1) and r is the radius of circle.
As we can see in the figure radius = 4units
<em>from centre(1,-2) to (1,-2)</em>
Put these into the equation
(x + 1)² + (y - 1)² = 4²
(x + 1)² + (y - 1)² = 16
b equals 0 I looked it up have a good day
Answer:
Triangle EFG has vertices E(-3, 4), F(-5, -1), and G(1, 1)
Step-by-step explanation:
Informally: When you multiply a whole number times itself, the resulting product is called a square number, or a perfect square or simply "a square." So 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers
The point 
is on the graph of the equation.
Explanation:
The equation is 
We need to determine the point is on the graph.
To determine the point is on the graph, we need to substitute the point in the equation and find whether the LHS is equal to RHS.
Thus, substituting the point in the equation , we get,
Multiplying the terms within the bracket, we have,
Adding the LHS, we have,
Thus, both sides of the equation are equal.
Hence, the point is on the graph of the equation
