The answer is d because x is horizontal

The correct answer is C. as when the slope is undefined, and the only coord you have is the x coord and it stays the same for all the points, then your answer would be a graph that has a line going straight up-and-down on the x=4 coord. Only when you have the y coord alone without an x coord is it going left-to-right on the graph. Hope this helps

Find the inverse of the function y=2x^2+2

GREYUIT [131]

Y = 2x^2 + 2
2x^2 = y - 2
x^2 = ( y - 2)/2

x = sqrt (1/2y - 1)

inverse = +/- sqrt ( 1/2 x - 1)

What is the quotient? n+3/2n-6 divided by n+3/3n-9

Stolb23 [73]

First some rewriting:

$\dfrac{n+3}{2n-6}\div\dfrac{n+3}{3n-9}=\dfrac{n+3}{2(n-3)}\div\dfrac{n+3}{3(n-3)}=\dfrac{\frac{n+3}{2(n-3)}}{\frac{n+3}{3(n-3)}}$

We see that the numerators of both fractions $(n+3)$ and a term in the denominators $(n-3)$ will cancel:

$\dfrac{n+3}{2(n-3)}\div\dfrac{n+3}{3(n-3)}=\dfrac{\frac12}{\frac13}$

Then

$\dfrac{\frac12}{\frac13}=\dfrac12\cdot\dfrac31=\dfrac32$

Find the equation of the line perpendicular to y=2x-6 that passes through the point (1,5). If possible, write the equation in sl

mr Goodwill [35]

Answer:

$y=-0.5x+4.5$

Step-by-step explanation:

The slope of $y=2x-6$ is:

$2$

The negative reciprocal of that slope is:

$m=-\frac{1}{2}$

So the perpendicular line will have a slope of $-1/2$ :

$y - y_1 = (-\frac{1}{2} )(x - x_1)$

And now put in the point $(1,5)$ :

$y-5=(-\frac{1}{2})(x-1)$

And that answer is OK, but let's also put it in $y=mx+b$ form:

$y-5=-\frac{x}{2}+\frac{1}{2}$
$y=-\frac{x}{2}+\frac{11}{2}$

$y=-0.5x+4.5$
