Answer:
The following solution is incorrect. The correct value of x is 7.
Step-by-step explanation:
Distribute 3 to (4x-15). When distributing, the value outside parentheses is multiplied to all the numbers inside the parentheses. Since the 3 was only multiplied to 4x, the solution is wrong.
Add 45 to both sides.
Divide by 12 from both sides.

Step-by-step explanation:
The formula tells you the diameter is 2 times the radius. Pick some values for radius and multiply them by 2 to get the diameter. The graph will be a straight line through the origin with a slope of 2.
(Strictly speaking, the graph should not extend to negative values, as negative values for radius and diameter make no sense in the real world.)
__
We did not put unit labels (cm, feet, yards, km, light-years, etc.) on the graph axes. For a slope of 2, the graph needs the same units on both axes. They can be whatever units of distance you might choose.
