I hope this helps. Keep in mind the 1/3 is slope and the 3 is y-intercept.










x- intercept is the point where graph of given function touches the x-axis,f(x) becomes 0 at the point where graph of given function touches the x-axis. Therefore, we would to solve x^2+6x−16=0 and find its root.





x-intercepts of the given quadratic function are 2 and -8 .
x^2 - 2x = 146
x^2 - 2x - 146 = 0
See attachment. The quadratic formula is needed in this case.
Answer:
first we will make them like fractions
so 1/5= 2/10 so it will be
2/10+3/10= 5/10
