Pick the correct description of the line x+3y=1
a)titled right upwards
b)titles right downwards
c)horizontal
d)vertical

I believe that the right answer is A.

Step-by-step explanation:

The equation has the type of: ax + bx = g

therefore:

x | 0 | 1

y | 1/3 | 0

so you take the points: (x, y) = (0, 1/3) and

(x, y) = (1, 0)

I don't know if that is correct, I am just stating my opinion!

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

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.
