Part a: using the table provided, create five points to demonstrate that for the function, there is exactly one output value for each corresponding input value. in your final answer, include all calculations and the completed table.

f(x) = 2/3 x -1

Sara made $253 for 11 hours of work. at the same rate how much would he make for 7 hours of work?

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.

Which angle is the smallest? also give me an explanation so i can complete it to other questions as well, : )
