Eand f are sets of real numbers defined as follows:
e = {v | v< 1 )
f = {v [ v> 7)
write euf and eu fusing interval notation.
if the set is empty, write no solution.

*for e the inequality is less than or equal to 1
*the second interval notation has an upside down u in the problem

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?
