Answer:
A. With each 9s fact you add another 9, which means you go straight down a row and back one space. This creates a diagonal pattern in the grid.
Answer:
x greater than and equal to -7
Step-by-step explanation:
Parabola touches at -7 and is going straight towards all positive integers
Therefore the domain is all numbers greater than or equal to -7
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis

We have the following points:

Substituting we have:

Thus, the equation is of the form:

We substitute one of the points and find "b":

Finally, the equation is of the form:

Answer:

At a race, there are 3 rows with 15 people in each row. How many total people are there?
Numerical expression- 15 times 3
