You develop an app to help students complete their homework. To earn money, you sell advertising space on the app’s main screen. An advertiser pays you $15 per month and an additional $0.004 each time the app is opened. Graph the linear equation that represents the monthly income y (in dollars) when the app is opened x times.

15 + 0.004 x = y

Step-by-step explanation:

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
