<h2>Answer:37 paintings of $50 and 15 paintings of $75</h2>
Step-by-step explanation:
Let be the number of paintings Ella sells for $
.
Let be the number of paintings Ella sells for $
.
Profit made through $ paintings is
Profit made through $ paintings is
So,total profit is given by
It is given that total profit is $
So, ..(i)
Given that the total number of prints is
So, ..(ii)
using (i) and (ii),
Equation of a line is .
A perpendicular bisector is a line that cuts a line segment connecting two points exactly in half at a 90 degree angle. To find the perpendicular bisector of two points, all you need to do is find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form.
Given that,
Endpoints of the line segment are () = (4, 1) and (
) = (2, -5).
First find the midpoints of the given line segment.
M =
=
M =
Now, Find the slope of the line :
It is perpendicular to the line with (4,1) and (2,-5)
Slope between () and (
) =
so,
the slope between (4,1) and (2,-5) =
= 3
perpendicular lines have slopes the multiply to get -1
3 times m=-1
m=
The equation of a line that has a slope of m and passes through the midpoints M(3,-2) is
if we want slope intercept form
If we want standard form
Hence, Equation of a line is .
