First, let x be the number of hours it will take for Hector to finish the same job alone. This means that every hour, Hector can do 1/x of the job. The amount of work done by Shawn and Hector in 6 hours should be equal to 1 complete work. This can be expressed as,
(1/9 + 1/x)(6) = 1
The value of x is 18. Thus, Hector can to 1/18 of the job in one hour.
Step-by-step explanation:
Transformations of graphs are fairly simple. Start with a parent function, or g(x) = f(x).
To move the graph UP or DOWN, add that number on the outside of the parenthesis with x: g(x) = f(x) + n is up, g(x) = f(x) - n is down.
To move the graph RIGHT you must SUBTRACT from inside the parenthesis. g(x) = f(x - n)
To move the graph to the LEFT you must ADD from inside the parenthesis . g(x) = f(x + n)
Answer:
i think -1/26
Step-by-step explanation:
(y2 - y1) / (x2 - x1)
(-15+16) /(-7-19)
1/-26
