Help asap help please.

Xelga [282]

Answer:

30(x+1)/(x+7)

Step-by-step explanation:

This is not a rational expression because denominator has a domain of which it can be undefined.

To rationalize multiply by the reciprocal of the denominator (1/6+1/x+1)

___5___ *(6)(x+1) --> _____30(x+1)_____ --> 30x+1_ --> 30x+1

1/6+1/x+1 *(6)(x+1)--> 6(x+1)/6 + 6(x+1)/(x+1) --> (x+1)+6 --> x+7

Final Answer: 30(x+1)/(x+7)

Geometry math question please help

Nikolay [14]

AD is perpendicular to BC so slope Ad = -1/slope of BC

Slope of BC = (2 - (-1)) / (- 6- 3) = 3 / -9 = -1/3

So slope of AD = -1 / (-1/3) = -3/-1 = 3 Answer

Write an equation for the line that passes through the given point and is perpendicular to the graph of the given equation.

Nezavi [6.7K]

Answer:

y + 2 = - 3/2(x - 4)

Step-by-step explanation:

Given line:

y + 4 = 2/3(x - 2)

It has a slope of 2/3.

Perpendicular lines have negative-reciprocal slopes, so the perpendicular slope is:

m = - 3/2

Find its equation provided it passes through the point (4, - 2):

y - (-2) = - 3/2(x - 4)
y + 2 = - 3/2(x - 4)
