What is the average rate of change of the function over the interval x = 0 to x = 6? f(x)=2x−1 3x+5 Enter your answer, as a frac
Tatiana [17]

Answer:

-11

Step-by-step explanation:

Our function is 2x-13x+5

  • 2x-13x+5= -11x+5
  • F(0)= 5 and F(6)= -11*6+5 = -61
  • let m be the average change : m= (-61-5)/6= -11

Solve the system of equations by substitution. What is the solution for x? (1 point)
Cerrena [4.2K]
                 2x + y = 1
          2x - 2x + y = 1 - 2x
                         y = 1 - 2x
                         y = -2x + 1
               4x + 2y = -1
    4x + 2(-2x + 1) = -1
4x + 2(-2x) + 2(1) = -1
          4x - 4x + 2 = -1
                         2 ≠ -1

The solution of the problem can't be a solution because they are both parallel lines, which means they have no solution.
