Is (0,4) a solution of 3x-4y=-4?

1 answer:

3 0

No. Because you have to put the 0 in the place of the X and the 4 in the place of the Y. Then do 3(0) which equals 0 then 0 - 4(4) 0 -16 is -16 and isn’t -4

The complete question is

In the figure to the right, if AC=19 and BC=16, what is the radius?

A circle has center A. Points B and D are on the circle, with B on the left and D near the bottom. Point C lies outside the circle such that the line segment A C passes through point D and the line segments A B and B C form a right angle.

The radius is approximately (Round to the nearest tenth as needed.)
