Answer:

Step-by-step explanation:
Given inequality:

In order to represent the solution on the number line, we will first solve the given inequality.
We have

Subtracting both sides by 4.


Dividing both sides by -3.
[On dividing both sides by a negative number the sign of the inequality reverses.]

So, solution of this inequality will range from -3 to -∞
The number line is represented below.

Answer:
216.66 yd²
Step-by-step explanation:
One way to find the area of a ring like this is to multiply its centerline length by the width of the ring.
Here, the diameter of the circle that is the centerline of the ring is 23 yd. The circumference of that circle is ...
C = πd = 3.14(23 yd) = 72.22 yd
Then the ring area is ...
(72.22 yd)(3 yd) = 216.66 yd² . . . area of shaded region

Answer:
Two solutions: -0.12 and 1.75.
Step-by-step explanation:
The quadratic formula is:
. Assuming that the x² term is a, the x term is b, and the constant is c, we can plug the values into the equation.
