The equation 12.5(x + 20) = 460 describes Steve's exercise plan for the next 12 weeks. He wants to bike 20 miles per week and run x miles per . week for a total of 460 miles. How many miles, x, should Steve run each week to achieve his goal?

f is the midpoint of

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
