Answer:

\frac{dy}{dx}=\frac{-y\sin xy}{1+\sin xy}

Step-by-step explanation:

\frac{dy}{dx}=-\frac{d}{dx} (xy) \sin(xy) \\ \\ =-\left(x \frac{dy}{dx}+y \right) \sin(xy) \\ \\ =-x \frac{dy}{dx} \sin(xy)-y\sin(xy) \\ \\ \frac{dy}{dx}(1+x\sin(xy))=-y \sin xy \\ \\ \frac{dy}{dx}=\frac{-y\sin xy}{1+\sin xy}

Zeros: x = 2, x = 4

Turning point: (halfway between the zeros) x = 3, y = -1

y-intercept: where x=0, at f(0) = 8.

Axis of symmetry: the vertical line through the turning point: x = 3.

3x + 2y = 14. X + y = 5. Work put the values of x and y
andrey2020 [161]

Answer:

x = 4 , y = 1

Step-by-step explanation:

3x + 2y = 14 → (1)

x + y = 5 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the y- term

- 2x - 2y = - 10 → (3)

Add (1) and (3) term by term to eliminate y

x = 4

Substitute x = 4 into (2) and evaluate for y

4 + y = 5 ( subtract 4 from both sides )

y = 1
