On Valterri’s last practice day, the team tracks his laps and total time on a graph, shown below. The team analyst also creates an equation from the race data, written as y=3.3x, where y = total time in minutes and x = the number of laps. Do the unit rates from the graph and the equation match? Why or why not?

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

Micah solves a linear equation and concludes that x = 0 is the solution. his work is shown below. (1 – 3x) = 4(– + 2) 0 = x which statement is true about micah’s solution?
