Answer:
Line A: constant of proportionality is 4/3
Step-by-step explanation:
The equation in question is y = (4/3)x, where (4/3) is the constant of proportionality as well s the slope of the line. The only line here that has a slope greater than 1 is the blue line (A).
I'm assuming you mean to list the terms of the expression. Those are mn, -2n, and +8. There are 3 terms there.
I think the answer is 37.7
You must multiply 5x-3 with 5, then you will get
25x-15 = 1
25x = 1+15
25x = 16

x = 0.64
now solve the quadretic eq. for the value of a
