Which expression fits this description? • The expression is the quotient of two quantities.
• The numerator of the expression is the product of 5 and the sum of u and y.
• The denominator is the product of negative 8 and 2.
5(x + y)
512+
5x +

a. 19,958,400

step-by-step explanation:

hope this

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

the ordered pairs for the given function are of the form
