Let f(x) = y = 5x - 7. Then f(3) = 5(3) - 7 = 8, and f(8) = 5(8) - 7 = 33
Then the ave. r. of c. of f(x) = 5x - 7 from x = 3 to x = 8 is
33 - 8 25
----------------- = -------- = 5 (answer)
8 - 3 5

Step-by-step explanation:
<em>Note:</em>
Where the 2 lines intersect is the solution to the systems of equations.
The first even multiple of 9 is 18.
Answer:
The correct answer would be never
Step-by-step explanation:
The systems of linear equations can have:
1. No solution: When the lines have the same slope but different y-intercept. This means that the lines are parallel and never intersect, therefore, the system of equations has no solution.
2. One solution: When the lines have different slopes and intersect at one point in the plane. The point of intersection will be the solution of the system
3. Infinitely many solutions: When the lines have the same slope and the y-intercepts are equal. This means that the equations represents the same line and there are infinite number of solution.
Therefore, based on the explained above, the conclusion is: Systems of equations with different slopes and different y-intercepts never have more than one solution.
I hope this helps
