To create an expression for income, a company multiplies the number of items they sell by the price of each item. If the income can be represented by the
expression -0.5x2+8x, and the price per item is represented by x, which of the
following expressions will represent the number of items sold.

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle

What percent of the circle below is shaded?

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?
