Answer:
y = 2x
Step-by-step explanation:
The equation that represents a proportional relationship that has a constant of proportionality equal to 2 is y = 2x
12(20-17) - 3*6
12 (3) - 18
12*3 - 18
36 - 18
18
Answer:
Option 2, 3, 4
Step-by-step explanation:
It cannot be the 1st option because a linear function doesn't have an 
and adding an x to an x will not make it squared. ax + by = c is the linear equation.
It can be the 2nd option because the quadratic formula is f(x) = a + bx + c and the middle portion could cancel when adding 2 together.
It can be option 3, because f(x) = a + bx + c plus ax + by = c could give you the resulting function f(x) = -3 +5
It can be option 4 because multiplying ax + by = c by ax + by = c would give you an .
It cannot be option 5 because a + bx + c multiplied by a + bx + c would give you a function with
