Answer:
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set. further the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
I hope it will help =)
Answer:
7/5
Step-by-step explanation:
To solve this problem we will use the formula to find the slope of a line given two points (x₁, y₁), (x₂, y₂)
The formula is:

So, we're going to use the points (2,5), (-3, -2) in this formula.

Therefore, the slope is 7/5
Step-by-step explanation:
so basically they are asking you to subtract, hope this helps, use a calculator if needed
Let x represent the number of students in Janelle’s group.
If Janelle brings 3 markers for each person in her group, then she brings 3x markers for x students. You also know that she brings <span>5 extra markers for everyone to share. Thus, the total amount of markers she brings is 3x+5.
</span>
If Janelle brings in 23 markers in all, then the equation <span><span>3x+5=23 </span> represaents the mathematical model. </span>
3x=23-5,3x=18,x=6
Answer: there are 6 students in Janelle's group.
