Since AB and BC are two parts of AC, AC = AB + BC
let's plug the expressions from the question into our equation above.
19 = 3x + 1 + 2x - 7
Combine like terms
19 = 5x - 6
Add 6 to both sides.
25 = 5x
Divide both sides by 5
5 = x

Answer:
for
, with
.
Step-by-step explanation:
To obtain x-intercepts, we need to give certain value, specifically
.
However, in case of a rational function, we must make sure that
doesn't makes the denominator null, beacuse in that case the function is undefined.
Therefore, for x-intercepts we must say
