7 \frac{2}{15 } + 5 \frac{2}{3} + 9 \frac{3}{15}

Convert mixed number to improper fraction.

\frac{107}{15} + \frac{17}{3} + \frac{148}{15}

Then change all the denominators into a same number

\frac{107}{15} +  \frac{85}{15} +  \frac{148}{15}

Add all the numerators but let all the denominators be same.

\frac{107+85+148}{15} = \frac{340}{15}

Change the improper fraction back into a mixed number..

22  \frac{10}{15} I see that we can still simplify the fraction.. 

22 \frac{10}{15} = 22 \frac{2}{3}

Your final answer is C. 22 \frac{2}{3}

1.
f(x) = x
g(x) = x + 3

For each x value you use in f(x) and g(x), the corresponding y value in g(x) is always 3 more than in f(x). If each y-coordinate is 3 more, that means the graph is shifted 3 units up. The graph of f(x) is shifted 3 units up to create the graph of g(x).

2.
The first term is -0.5.
Then each term goes up by 0.25.

1st term: -0.5
2nd term: -0.5 + 0.25 = -0.5 + 0.25(1)
3rd term: -0.5 + 0.25 + 0.25 = -0.5 + 0.25(2)
4th term: -0.5 + 0.25 + 0.25 + 0.25 = -0.5 + 0.25(3)
nth term: -0.5 + 0.25(n - 1)

-0.5 + 0.25(n - 1) = -0.5 + 0.25n - 0.25 = -0.75 + 0.25n = 0.25n - 0.75
