In one month, there are on average 30 days.
So if he talks 135 minutes per month, he talks on average 135/30 minutes per day
135/30 = 4.5
So on average he talks to his grandfather for 4 minutes and 30 seconds a day.
Answer:
Combining like terms is just that, combining numbers in an equation that have the same property. examples would be constants or numbers with the same exponent.
Properties of exponents are when you multiply, add, subtract, or divide exponents.
I hope I helped!
(-∞,4). All I did was isolated x, and it says that x has to be less than 4. That means anything before 4 is fair game. Since the problem said that it can't be equal to 4 (as it would have had to have a line under the less than symbol), I used parenthesis on the 4 side as opposed to hard brackets. The <span>∞ always requires parenthesis. </span>
By using any two of the points in the table, we will see that the slope is -2.

How to get the slope for the linear relationship?</h3>
A general linear relationship is:
y = a*x + b
Where a is the slope and b is the y-intercept.
Remember that if the line passes through (x₁, y₁) and (x₂, y₂), the slope is:

Here we can use the first two points on the table:
(-4, 11) and (2, -1), so the slope is:

Then the slope of the line is -2.
