Answer:
Step-by-step explanation:
A(10,10) B(b,10b)
ax-2y=30
Divide both parts of the equation by 10:
a=5
Hence,
5x-2y=30
5(b)-2(10b)=30
5b-20b=30
-15b=30
Divide both parts of the equation by -15:
b=-2
Thus,
a=5 b=-2
Divide both parts of the equation by 2:
2.5x-15=y
The equation of the perpendiqular bisector
Hence,
Let 
and 
be, respectively, the length and the width of the rectangle.
If the length is 4 inches more than the width, we have
Moreover, the perimeter of a rectangle is given by
And we can substitute 
to get
We know that the perimeter is 34 inches:
Which implies

She would make $98.50 in 10 hours.
Explanation :
255/20 = 12.75
12.75 - 2.90 = 9.85
9.85 x 10 = 98.50
