Question 7 of 10 Suppose there is a simple index of two stocks, stock A and stock B. Stock A
opens on Monday with 8000 shares at $4.75 per share. Stock B opens on
Monday with 5000 shares at $5.12 per share. Stock A opens on Tuesday at
$5.40 per share, and stock B opens on Tuesday at $5.72 per share. Both
stocks have the same number of shares that they opened with on Monday.
What is the rate of change of this simple index over 1 day?
O A. -11.4%
B. -12.9%
O C. 11.4%
O D. 12.9%

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

step-by-step :

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.
