Rates are used to show how a quantity measures over another.
Andy does not read at a constant rate.
The table is given as:
Pick any two points from the table:
The rate (m) is then calculated as:
So, we have:
Pick another point from the table
The rate (m) is then calculated as:
The rates calculated are not equal
<em>i.e. 0.3 and 0.5 are not equal</em>
This means that;
Andy does not read at a constant rate.

Answer:
The x intercept is (-5,0)
The y intercept is (0,-3)
Step-by-step explanation:
To find the x intercept we set y=0 and solve for x
3x+5y = -15
3x+0 = -15
3x = -15
Divide by 3
3x/3 = -15/3
x = -5
The x intercept is (-5,0)
To find the x intercept we set x=0 and solve for y
3x+5y = -15
0+5y = -15
5y = -15
Divide by 5
5y/5 = -15/5
y = -3
The y intercept is (0,-3)
The answer is B. 5P5 x 20P15.
This is because to make the second grade students to sit in the first row we have 5 seats and 5 students so we will permute the 5 students to those 5 seats. So 5P5.
Now we are left with 20 seats and 15 first grade students so we can simply permute those 15 students into those 20 seats. So 20P15.
Finally using the counting rule principle we will multiply both of these so 5P5 x 20P15.
Answer:
