Answer: The domain of a function represents all the possible input values or independent variables that can be used in the function. In this case, the function models the relationship between the number of workers and the number of bricks laid on the wall.
To determine the domain, we need to consider what values the number of workers can take on in this relationship. Since the number of workers is discrete, it means that only whole numbers can be used to represent the number of workers. For example, you cannot have 2.5 workers.
Therefore, the domain of the function would be a set of whole numbers. We can represent this using interval notation as {0, 1, 2, 3, ...}, where the ellipsis (...) indicates that the pattern continues indefinitely.
Area of the wall = 12 ft * 14 ft = 168 ft^2
Each wall is coated thrice with the paint.
Therefore, 168ft^2 * 3 = 504 ft^2
150ft^ 2 = 1 gallon paint.
Therefore 504 ft^2 requires
= 504/150
= 3.36 gallons of paint

Answer: the third graph
Step-by-step explanation:
Ok so one way to do this is by plugging in points which is long but easiest. So since it’s the absolute value, whenever it passes the y- axis to the negative side, it will go up. So we know it’s either the third or last. The y intercept is -2, and the graph with that is the third.
Answer:
The third option.
Step-by-step explanation:
{x | x R, x < -15}
{x | x R, x > -5}
{x | x R, x < 5}
{x | x R, x > 15}
Answer:
B.
Step-by-step explanation:
We have been given an inequality. We are asked to choose the solution set for our given inequality.
First of all, we will separate variable x on one side on inequality as:
Therefore, the solution for our given inequality are all values of x greater than and option B is the correct choice.
