Equation A is linear and equation B is nonlinear
You can plug them each of them into a graphing calculator into y= and then check the table and compare which one is correct. Hope this helps
B = (2x+3)(4x^2-6x+9)-2(4^3-1)
B = 8x^3-99
Hope it helps : )
start with y= m(x+9)
Use the distributive property:
y= mx+9m
Now you want x to decrease by 6:
so y ' = m(x-6) + 9m
Use distributive property again:
y'= mx - 6m + 9m
y' = (mx+9m) - 6m
y' = y - 6m
So the value of y decreases by 6m.
Answer:
the first two answers are perpendicular
