The answer for this question is A
A is located at (1,3) D is located at (5,0)
distance formula is sqrt((x2-x1)^2 +(y2-y1)^2)
= sqrt(( 5-1)^2 + (0-3)^2)
= sqrt((4^2 +-3^2)
= sqrt (16+9)
= sqrt(25)
= 5
distance is 5 units
X=number of books that cost 0.60
y=number of books that cost 0.75
x+y=16
0.6x+0.75y=10.95
solve
multiply second equation by 10 for nicity
6x+7.5y=109.5
multiply first equesiotn by -6 and add to second
-6x-6y=-96
<u>6x+7.5y=109.5 +</u>
0x+1.5y=13.5
1.5y=13.5
divide both sides by 1.5
y=9
sub back
x+y=16
x+9=16
minus 6
x=7
seven 0.60 books and nine 0.75 books

Answer:
Step-by-step explanation:
Choosing two points on the dotted line to find equation of line.
The points are:
and
Slope of line can be calculated as:
Using point slope equation to find equation of dotted line.
where represents slope of line and represents y-intercept.
The y-intercept for the dotted line = 6 as it intersects the y-axis at (0,6)
So, the equation of line is:
The dotted line indicates that the line is not included in the solution.
The solution of the inequality is below the dotted line, so thus it would be less than the line.
So, the inequality would be:
