Not sure how to solve this

Step-by-step explanation:

In the table, they give you an x-value.  Use the x-value to solve for y.  You will then get a point.  Plot the points to find the graph.

y = 1/2x

y = 1/2(0)

y = 0

(0, 0)

y = 1/2x

y = 1/2(2)

y = 1

(2, 1)

y = 1/2x

y = 1/2(-4)

y = -2

(-4, -2)

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
