Astudent translated the phrase below into an algebraic expression, and then evaluated if for y = 24. is the student's
work correct?
the difference of a number and 6; evaluate when y = 24
the expression is l. for y = 24, y - 24 - 4.
66
no, the student wrote a division expression instead of a subtraction expression
no, the student simplified the fraction incorrectly.
no, the student made an error when substituting,
yes, the student's work is correct.

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.

Cole says the distance between points (-5,0) and (0,-5)is 5 units. is he correct? explain why or why not.
