Answer:

r = -6

Step-by-step explanation:

6(r - 8) = 8r - 36

distribute 6 into r - 8

6r - 48 = 8r - 36

add 36 to both sides

6r - 12 = 8r

subtract 6r from both sides

-12 = 2r

divide by 2 on both sides

-6 = r

Find an equation of the line perpendicular to the graph.

topjm [15]

Answer:

The equation of the line would be y = -1/4x + 2

Step-by-step explanation:

In order to solve this, start by finding the slope of the original line. You can do this by solving for y.

28x - 7y = 9

-7y = -28x + 9

y = 4x - 9/7

Now that we have a slope of 4, we know that the perpendicular slope is -1/4 (since perpendicular lines have opposite and reciprocal slopes). We can use this and the new point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - 1 = -1/4(x - 4)

y - 1 = 1/4x + 1

y = -1/4x + 2

Answer:

The slope of Function 2 (m=1.1) is greater than the slope of Function 1 (m=1).

Step-by-step explanation:

First, note that p is essentially the y and that r is the x. Thus, to make this easier to see, convert p to y and r to x. Thus:

$y=x+7$

From the above equation, we can determine that the slope is 1. Thus, the slope of Function 1 is 1.

To find the slope of the table, simply use the slope formula. Use any two points. I'm going to use the points (0,8) and (10,19). Let (0,8) be x₁ and y₁, and (10,19) be x₂ and y₂. Therefore:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{19-8}{10-0}=11/10=1.1$

Thus, the slope of Function 2 is 1.1.

1.1 is greater than 1.

Thus, the slope of Function 2 is greater than the slope of Function 1.

Solve 3/x+2 - 1/x = 1/5x. Show your work.

Temka [501]

( 3x - x -2) / x (x + 2) = 1/5x (2x - 2) / x(x +2) = 1/5x 2x - 2 = (x + 2) / 5 10x - 10 = x + 2 9x = 12 x = 12/9 x = 4/3
