The number that belongs in the blank space is answer choice A. 6
Answer:
The rate of change in -4
Step-by-step explanation:
The rate of change is also known as the slope
To do this, take two points {(-2, 17) , (-1, 13)} and find the slope
m = slope
m = change in y/change in x
m = 13 - 17/-1 - (-2)
m = -4/1
m = -4
The rate of change in -4
Suppose the number is x, its reciprocal is 1/x
x+1/x=13/6
(x^2+1)/x=13/6
6(x^2+1)=13x
6x^2-13x+6=0
(3x-2)(2x-3)=0
x=2/3 or x=3/2
