Find the equation of the line through (8,−6) which is perpendicular to the line y=x3−7.
ycow [4]

Answer:

y = (-1/3)(x + 10)

Step-by-step explanation:

The slope of the new (perpendicular) line is the negative reciprocal of the slope of the given line, which appears to be 3.  Thus, the perpendicular line has the slope -1/3.

Using the slope-intercept form y = mx + b, and substituting the givens, we obtain:

y = mx + b    =>    -6 = (-1/3)(8) + b, or

-6 = -8/3 + b.  We must solve for the y-intercept, b:

Multiplying all three terms by 3 removes the fraction:

-18 = -8 + 3b.  Thus, -10 = 3b, and so b must be -10/3.

The desired equation is    

y = (-1/3)x - 10/3, or

y = (-1/3)(x + 10)

What is the store paid $75 for a clarinet and sold it for $100 did the store mark up the price by 30% what the answer
nevsk [136]

Answer:

Mark up  = 33.33%

Step-by-step explanation:

Given that:

buying price = $75

selling price = $100

First we will find the difference between two prices:

Difference = 100 - 75 = $25

We will find now that 25 is what percent of 75 so:

=25/75* 100

=  0.333333 * 100

= 33.33%

So the store marked the price by 33.33% instead of 30%

i hope it will help you!

What is the smallest degree of rotation that will map a regular 18-gon onto itself?
Korolek [52]
Because the 18-gon is symmetrical, you can rotate it by 360/18 or 20 degrees. This is because when you rotate it by 20 degrees(to the left for explanation matters), any angle will now be in the position of its angle to its left.

2x+3y= -18 on the graph
enot [183]

Answer:

graph two points at the coordinates (-6, 0) and the coordinates (-8, 3), and make a line through them.

Step-by-step explanation:

First simplify. 2x+3y= -18.,   -----------> 3y= -2x -18., ---------> y= -2/3x -6

To graph this you would first go to the coordinates (-6, 0) and put a point there. Next, you would go to the coordinates (-8, 3) and put a point there. Then make a line and you are done. That should be right.
