We assume w is the number of <em>inches</em> of width (as opposed to <em>feet</em> or some other measure). The length is 7 inches more than the width, so is w+7. The area is the product of these dimensions, and the problem statement tells us that area is greater than 375 in².
... w(w+7) > 375 . . . . . the inequality that can be used to find dimensions
<h2>Answer</h2>

<h2>Explanation</h2>
The first thing we need to do is find the slope of our line. To do it we are using the slope formula:

where
is the slope of the line
are the coordinates of the first point on the line
are the coordinates of the second point
From our graph we can get the points (0, 43) and (2, 55), so
,
,
, and
. Let's replace the values in our slope formula:



Now that we have our slope, we can use the point-slope formula:



But remember that the equation of a line in standard form is
, so we need to subtract
and add 43 to both sides of our point slope equation:



We can conclude that the equation in standard form that represent the relationship in the graph is
.
Your answer would be A.
i chose this by substituting the 11 and 7 for "d", which is distance.
c= .50(11)+1.7
c=7.2
c=.50(7)+1.7
c=5.2
Answer:
The parabola obtained is x=y²
Step-by-step explanation:
Given the focus (1/4,0) and directrix: x=-1/4
A point on the parabola is determined by the distance of that point with the focus and with the directrix:
Distance between the parabola and the directrix:
Distance between the parabola and the focus:
=
=



x=y²
