To find the difference between these numbers you need to subtract 8.3 - 3.9
and that equals 4.4<span />
In this problem, you are simply going to input 14 for x in your equation.
y = 3x + 1
y = 3(14) + 1
y = 42+1
y = 43
This means, when x=14, y=43
Hope this helps!
4x + 1 = x^2 + 3x - 1
4x = x^2 + 3x - 2
0 = x^2 -x - 2
0 = x^2 -x + 1 - 3
0 = (x - 1)^2 - 3
3 = (x - 1)^2
sqrt 3=(x-1) and (-(x-1))
x = 1+sqrt 3 and 1-sqrt 3
sqrt means square root
