3) all of 3 is 63 degrees

all of those are rigid motions, meaning none of the angles change

4) Same length and same distance from each other. We know this because a translation is a rigid motion

Hope this helps.

If y = 3x and 2x + 4y = 12, then 2x + 4(3x) = 12

Kamila [148]

Answer:

x=6/7 and y=18/7

Step-by-step explanation:

If y = 3x and 2x + 4y = 12,

then substitute the value of y with 3x

2x + 4(3x) = 12

2x+12x=12

14x=12

x=12/14=6/7

y=3x=3*(6/7)=18/7

Xy=1 for x=2, dx/dt= -2 find dy/dt

dexar [7]

$\bf xy=1\iff y = \cfrac{1}{x}\iff y = x^{-1}\\\\
-----------------------------\\\\
\cfrac{dy}{dt}=-x^{-2}\cdot \cfrac{dx}{dt}\impliedby \textit{using the chain-rule}
\\\\\\
\left. \cfrac{dy}{dt}=-\cfrac{\frac{dx}{dt}}{x^2} \right|{
\begin{array}{llll}
x=2\\
\frac{dx}{dt}=-2
\end{array}}\implies \cfrac{dy}{dt}=-\cfrac{-2}{2^2}$

Bisector is simply a straight that divides the line (through which it's passing) into two equal halves. Or simply, it passes through the midpoint of any line. It may make any angle with the line through which it passes.

Perpendicular Bisector is also the same but the only difference is that it makes an angle of 90° with the line through which it passes or cuts.
