Which algebraic expression models the word phrase one less than the product of six and w?

You are on a bicycle trip. You traveled 52 miles the first day. Since then, your average rate has been 12 miles per hour. Write an algebraic expression that models the distance you traveled so far? Use h as the variable.

Graph the solution to the system. The first equation has been plotted for you.

y = -3x-3

y= 4x +4

What is the value of y in the solution to this system of equations? 3x - 5y = 22 y = -5x + 32
