Barry can do a certain job in 3 hours, whereas it takes Sanchez 8 hours to do the same job. How long would it take them to do the job working together?

Given the conditional statement, match the following. conditional statement: if two lines intersect, then their intersection is one point.

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

I'm confused on this could anyone me and show me what i need to do to solve it.
