Solution:
x/3-2/5 = 2x/15-3/5
(x/3)/15 - (2/5)/15 = (2x/15)/15 - (3/5)/15
5x - 6 = 2x - 9
5x = 2x - 9 + 6
5x - 2x = -9 + 6
3x = -3
3x/3 = -3/3
x = -1
Therefore the value of x is -1

Answer:
y=2x+12
Step-by-step explanation:
Turning points are inflection points
think
1st degree (linear) has no turning/inflecion points
2nd degree (quadratic, parabola) has 1 turning/inflection point
so
nth degree has n-1 turning/inflection point
this is 11th degree since highest power is 12
12-1=11
11 turning oints
