Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Solve for the inequality
Adds 5 both sides


Divide by 2 both sides


The solution is the interval ------> (-∞,10)
All real numbers less than 10
In a number line , the solution is the shaded area at left of x=10 (open circle)
The graph in the attached figure
It is given that the circumference of the circle is 19.5 inches. Let the diameter is d inches .
And the formula of circumference is

Substituting the value of C, we will get

When the diameter increased by 3, then the circumference is

And the circumference , when diameter is increased by 3 is 29 inches .
Circumference = 2 x pi x radius
27 in = 2 x 3.14 x radius
Solve for the radius
