Answer:
[0,1] and [-1,0]
Step-by-step explanation:
We have the function to determine consecutive values of x between which each real zero is located we have to replace the function with different values and then analyze the results.
We are going to replace the function with x=0,
Now we are going to replace with x=1,
With x=2,
Now with x=-1,
With x=-2,
We have to analyze:
We have that f(2) and f(1) have the same signs both are negatives this means that there isn't a zero between the interval [1,2].
We have that f(1) and f(0) have opposite signs this means that there is a zero between the interval [0,1].
f(0) and f(-1) have opposite signs too, then there's also a zero in the interval [-1,0].
And finally, f(-1) and f(-2) have the same signs then there isn't a zero in the interval [-2,-1]
The graph of the function shows that the answer is correct:
The value of x in the equation is 4.2.
<h3>How to calculate the value?</h3>
It should be noted that the equation given is:
12(-11x + 5) + 7 = 2 (x-9) - 451
This will be computed thus:
12(-11x + 5) + 7 = 2 (x-9) - 451
-132x + 60 + 7 = 2x - 28 - 451
Collect like terms
-132x - 2x = - 28 - 451 - 60 - 7
-130x = -546
Divide
x = 546/130
x = 4.2
The value of x in the equation is 4.2.
