WebStep 2: Substitute that equation into the other equation, and solve for x x x x. 5 x + 4 y = 32 Equation 2 5 x + 4 ... -1 = x + y Now to get x by itself, we can subtract y from both sides. -1 = x + y-1 - y = x + y - y-1 - y = x Hope that helps. WebCorrect option is D) Given y=x 4. ⇒y=4x 3. ⇒y =12x 2=0 for x=0. Hence, x=0 is a possible point of inflection, but we need to verify. So, check in the neighborhood of 0, f (0 +)=12(0 +) 2>0 and f(0 −)=12(0 −) 2>0.
