Help with question 8 a and b)

I think when you subtract 4 from x, you are shifting the graph right horizontally 4 units.  When you add 84 at the end of the function, you are shifting it up vertically 84 units.  When you times it by -5, you are stretching it by a factor of 5 and flipping it upside down.

just think of how each term effects the y value.

The center of a circle is 5 units below the origin, and the radius is 10 units. what is the equation of the circle?
levacccp [35]

Answer:

x² + (y + 5)² = 100

Step-by-step explanation:

If the center of the circle is 5 units below the origin, its x coordinate is 0 and its y-coordinate is -5. So, the center of the circle is at (0, -5).

Using the equation of a circle with center (h, k)

(x - h)² + (y - k)² = r² where r = radius of the circle.

Given that r = 10 units, and substituting the values of the other variables into the equation, we have

(x - h)² + (y - k)² = r²

(x - 0)² + (y - (-5))² = 10²

x² + (y + 5)² = 100

which is the equation of the circle.
