Choose a value for b so that the relation below is not a function.

Elena-2011 [213]

Answer:

B. -2

Step-by-step explanation:

A relation that is not a function would have one x-value having two different corresponding y-values.

If we choose -2 to represent b I the relation, the relation would not be a function. This is because, we there would be two different y-values, 8 and 1, that are assigned to one x-value, which is -2 ==> (-2, 8) and (-2, 1).

What are the coordinates of the center of a circle whose equation is (x + 7)2 + (y – 5)2 = 16?

Dafna11 [192]

Hi there! The answer is ( - 7, 5)

The standard form of the equation of a circle is the following:
$(x - a) {}^{2} + (y - b) {}^{2} = r {}^{2}$

In this equation r represents the radius of the circle and the point (a, b) is its centre.

Therefore, the centre of the circle
$(x + 7) {}^{2} + (y - 5) {}^{2} = 16$
is the point ( - 7, 5).
