answer: there are x+184 pages in olivia's book.
let the total number of pages in the book which olive has already read be x.
then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read
therefore, the total number of pages in olivia's book=
hence, there are x+184 pages in olivia's book.
to plot points for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere
now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.
you have just plotted a point! now when you finish plotting all of them connect them with a ruler
plot each point as (-3, 7), (0,4), (3,1), (8,-4) in the parenthesis on the left of the comma is x and the right is y.
the given function is ,
the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.
if a quadratic equation is of the form ,
sum of the roots = a + b +c= 0+8+10=18=
product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =
product of roots = a b c = 0=
there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
