120 times because 300 divided by 25
B) y = -2x
when x = a
y = -2a
when x= 2a
y = -2(2a) = -4a
Answer:
Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate.
so i assume it could be 162 sorry if i am wrong let me know if it is right or not
We can compare by converting Johnny's reading time into the same unit of Jacky's, hours.
There are 60 minutes in an hour, so use this:

15 < 20, so Johnny read faster. This is 5 pages faster per hour than Jacky.
sqrt(575) = 23.979
so 23 is one number
575/23 = 25
the two numbers would be 23 * 25
25 is the largest one
