I need to know if this H(3,2),J(4,1),K(-2,-4),M(-1,-5) is parallel perpendicular or neither I need to show my work and write my

Shkiper50 [21]

Answer:

Step-by-step explanation:

H(3,2) & J(4, 1)

$Slope = \dfrac{y_{2} -y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{1-2}{4-3}\\\\\\=\dfrac{-1}{1}\\\\= -1$

K(-2,-4) & M(-1 , -5)

$Slope =\dfrac{-5-[-4]}{-1-[-2]}\\\\=\dfrac{-5+4}{-1+2}\\\\= \dfrac{-1}{1}\\\\\\= -1$

Line HJ and KM have same slopes. So, they are parallel

<h3>Answer:</h3>

a. -(3√13)/13

<h3>Step-by-step explanation:</h3>

The cosine can be found from the tangent by way of the secant.

tan(θ)² +1 = sec(θ)² = 1/cos(θ)²

Then ...

cos(θ) = ±1/√(tan(θ)² +1)

The <em>cosine is negative in the second quadrant</em>, so we will choose that sign.

cos(θ) = -1/√((-2/3)² +1) = -1/√(4/9 +1) = -1/√(13/9)

cos(θ) = -3/√13 = -(3√13)/13 . . . . . matches your selection A

Inverse for f(x)=1/2x+3

Semenov [28]

Answer: $f^{-1}(x)=2x-6$

Step-by-step explanation:

To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.

$y=\frac{1}{2}x+3$ [switch x and y]

$x=\frac{1}{2}y+3$ [subtract both sides by 3]

$x-3=\frac{1}{2} y$ [multiply both sides by 2]

$y=2x-6$

Now, we know that $f^{-1}(x)=2x-6$ .
