#10. Sam: (4, 2); Theater: (-3, 5) #11. Sam is 3 km south and 7 km east of the theater. #12. (-3, -4) #13. (-3, 0.5) #14. T (0.75, -1.0); U (0.75, 1.25); V (-0.75, 1.25) #15. W(-0.75, -1.0) #16. Janine is describing points that lie on the y-axis. Ordered pairs that lie on the x-axis have a y-coordinate of 0. The origin lies on the x- and y-axis. Any other point with an x-coordinate of 0 lies on the y-axis such as (0, 3).

I hope this helps joseph.. ^^ gl

$y+8 = \frac{1}{2}(x-7)$ is equivalent to <span> $y-(-8) = \frac{1}{2}(x-7)$

That is in the form </span><span> $y-y_{1} = m(x-x_{1})$ which is point slope form

In this case,

m = 1/2 is the slope
(x1,y1) = (7,-8) is the point the line goes through</span>

Ed planned to read 25 pages a day of his favorite book by some deadline. However, he read 8 pages more a day and there were just

GaryK [48]

Answer:

175 pages

Step-by-step explanation:

Let's call 'd' the number of days before the deadline, and 'n' the total number of pages of the book.

We have the following equations:

(1) $25 d = n$ --> if we multiply the number of pages per day (25) times the number of days (d), we get the total number of pages of the book (n)

(2) $(25+8)(d-2)=n-10$ --> he reads 8 pages more per day (so, 25+8), for a number of days equal to (d-2) (d is the deadline), and he reads a total of n-10 pages (because only 10 are left)
