Given that <span>Rashawn read 25 pages of his book each day until he finished the book. His book was 400 pages long.
The number of days it takes him to finish the book is given by 400 / 25 = 16 days.
In 0 days, he has 400 pages remaining and in 16 days he has 0 pages remaining.
Therefore, the graph that represents the situation is a</span><span>
graph in the first quadrant containing a line segment. The x axis is
labeled Days and the y axis is labeled Pages remaining. The endpoints of
the line segment are (0, 400) and (16, 0).</span>
Answer:
<em>a = 1 ; b = - 8 </em>
Step-by-step explanation:
x² + 2x - 7 = (x² + 2x + 1) - 1 - 7 =<u><em> (x + 1)² - 8 </em></u>
<em>a = 1 </em>
<em>b = - 8</em>

Answer:
axis of symmetry: x = 2
see below for a graph
Step-by-step explanation:
You can complete the square to put the equation in vertex form.
y = (x^2 -4x +4) -1 -4
y = (x -2)^2 -5 . . . . . . vertex is (2, -5)
The equation of the axis of symmetry is the equation of the vertical line through the vertex:
x = 2 . . . . . axis of symmetry
__
Points on the graph are easily found by using integer values on either side of x=2. Points on one side of the axis of symmetry are mirrored on the other side of it.
One example could be, 2 • (9x + 6y)
