2y + 2(y-2) = 5y - 3(y-10)
2y + 2y - 4 = 5y -3y +30
4y - 4 = 2y + 30
4y - 2y = 30 + 4
2y = 34
y = 34/2
y = 17

Suppose Quadrilaterals A and B are both squares. Are A and B necessarily scaled

nevsk [136]

Answer:

Yes

Step-by-step explanation:

A rectangle can be scaled into a square + rhombus. The difficult part is a trapezoid. If you can scale the sides, then the answer will remain yes because you would just make the top side longer both ways to straighten it and shorten the side lines.

سا (a) From the definition of derivatives determine dy÷dx if y = -2÷x

harina [27]

Step-by-step explanation:

Given: $y = -\dfrac{2}{x}$

Derivative of a power function $x^n$ :

$\dfrac{d}{dx}(x^n) = nx^{n-1}$

Therefore,

$\dfrac{dy}{dx}=-2(-1)x^{-2} = \dfrac{2}{x^2}$
