Domain: (-infinity, infinity)
All linear equations(unless they have restrictions) will have a domain that goes on forever in both directions of the x-axis
You give them to people answering your questions. And you get them from questions you've answered! Hope this helps
The coefficient of the term 13a is 13
The coefficient of 6b in expression is a + 6b is 6
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
13a + 6b
We have to find the coefficient of 13a
The coefficients are the numbers that multiply the variables or letters
Here in 13a , a is the variable that is multiplied with number 13
Thus the coefficient of the term 13a is 13
<em><u>Second expression:</u></em>
a + 6b
Here, in 6b , b is the variable that is multiplied with number 6
so 6 is the coefficient
