Answer:
B. Step 4 is incorrect , it should be
Step-by-step explanation:
6x-1= -2x+9
Step 1
Collect like terms and change signs if you move anything from one side to the other; 6x+2x = 9+1
Step 2: Add like terms on both sides
8x = 10
Step 3: To remain with just x on one side, divide both sides by 8 and it becomes;
The two 8s cancel each other and you remain with
0.026, 0.071, 0.079, 0.089
It is 50 because a triangle needs to be equal to 180 degrees
Answer:
x ≈ 1.683006
Step-by-step explanation:
There are many successive approximation techniques. For these functions, it seems to work to solve the equation for x:
6^(-x) +4 = 3x -1
6^(-x) +5 = 3x . . . . . . add 1
(6^(-x) +5)/3 = x . . . . divide by the coefficient of x
Then we can use the function ...
f(x) = (6^(-x) +5)/3
to find a new value of x, given an initial value of x.
As we read the graph, the point where the curves cross is at about x=1.7, so that will be our initial starting point for iteration. The attachment shows the successive values of f(x) for three iterations. The third evaluation of f(x) gives an approximate root value of ...
x ≈ 1.683006
