What is the solution of the system of equations? y=6x^2+ 3x – 11
y= 3x - 5
A. (x, y) = (-2,1) and (x, y) =(-8,-1)
B. (x, y) = (1,-1)
C. (x, y) =(-1,-8)
D. (x, y) = (1,-2) and (x, y) =(-1,-8)

easy math just plug in a and b

step-by-step explanation:

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

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.
