Answer:
8+2j like you say let j be the variable and more than means+
Y= 4/3x -1 use y2-y1 over x2-x1
63/240 seats or 21/80
The greatest common denominator is 3, so you would divide both by 3.
The answer is y=-3/4+5 because y=mx+b
m:slope
(x,y):any point on the line
(0,b): y-intercept of the line
The domain is actually the x value of the function, so we need to find the value of x
suppose the width is x, the length is then 3x+5
the area is 50^2 inches, so x(3x+5)=50 => 3x^2+5x-50=0
Factor this quadratic equation: (x-5)(3x+10)=0 =>x=5 or x=-10/3
width can not be negative, so the width is 5
the domain is x=5
