My brain wants me dead Let h(x) = x? - 8x.
(a) Find the average rate of change from 5 to 7.
(b) Find an equation of the secant line containing (5, h(5)) and (7, h(7)).
(a) The average rate of change from 5 to 7 is . (Simplify your answer.)
(b) An equation of the secant line containing (5, h(5)) and (7, h(7)) is ..
(Type your answer in slope-intercept form.)

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities

How do you write a paragraph proof to prove that the corresponding angles shown are congruent

Aclassmate thinks that solving a system by graphing gives an exact answer when the lines appear to cross at a grid point, but only an approximate answer when they don't. explain why this isn't true.
