Last summer kevin had $400 im his saving account. After 6 months he had a total of $580 in the account. Using this information, how can you describe the rate of change in the dollar amount in the account per month

$30/month

Step-by-step explanation:

The value of Kevin's account increases from $400 to $580 in 6 months, or

$180 in 6 months.  This comes to $30/month (the desired measure of the rate of change).

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

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.
