What is the equation for the line of reflection for ABCD to A’B’C’D’? Explain.

expeople1 [14]

Answer:

$y = \frac{4}{5} x - \frac{1}{5}$

Step-by-step explanation:

calculate midpoint of AA'

calculate midpoint of DD'

A(-5,1)

A'(-1,-3)

D(1,5)

D'(3,1)

then midpoint is

$\frac{x_{d} + x_{d^{1}}}{2} = 2 \\ \frac{y_{d} + y_{d^{1}}}{2} =3 \\ \\ \frac{x_{a} + x_{a^{1}}}{2} = - 3 \\ \frac{y_{a} + y_{a^{1}}}{2} = - 1$

then find slope

$\frac{ y_{2} -y_{1}}{x_{2} -x_{1}} = \frac{4}{5}$

then apply equation

$y = \frac{4}{5} x + b$

substitute any point of the 2 midpoints to find b

$b = \frac{ - 1}{5}$

then the equation is

$y = \frac{4}{5} x - \frac{1}{5} \\$

10 points! thank you

timurjin [86]

Answer:

Step-by-step explanation:

The equation of a line is represented as $y = 5x$ .

If we have no y-intercept (b) on the line, then we know that the point passes through the origin because it's a proportional relationship with no added constant: if x is 0, 5 times 0 is 0.

This means that the x-value of the x-intercept is 0.

Hope this helped!

Solve formula for V B=3 V/h

Rudiy27

Answer: $V=\frac{hB}{3}$

Step-by-step explanation:

We are given the equation $B=\frac{3V}{h}$ . We want to isolate V.

$B=\frac{3V}{h}$ [multiply both sides by h]

$hB=3V$ [divide both sides by 3]

$V=\frac{hB}{3}$

Now we know $V=\frac{hB}{3}$ .

Which expression is equivalent to (16x^8y^-12)1/2

Lady_Fox [76]

$(16x^8y^{-12})^\frac{1}{2}=(4^2x^8y^{-12})^\frac{1}{2}=(4^2)^\frac{1}{2}(x^8)^\frac{1}{2}(y^{-12})^\frac{1}{2}\\\\=4^{2\cdot\frac{1}{2}}x^{8\cdot\frac{1}{2}}y^{-12\cdot\frac{1}{2}}=4^1x^4y^{-6}=4x^4y^{-6}=\dfrac{4x^4}{y^6}\\\\\text{Used:}\\\\(a\cdot b)^n=a^n\cdot b^n\\\\(a^n)^m=a^{n\cdot m}\\\\a^{-n}=\dfrac{1}{a^n}$
