Slope intercept form: y = mx + b

m = slope and b = y-intercept

From y = 5x - 1 we can already see that the slope is 5 since it is already in slope intercept form.

The slope of the perpendicular line is the negative reciprocal of the slope for the equation y = 5x - 1.

The negative reciprocal of 5 is -1/5.

So the incomplete equation for the perpendicular line is y = -1/5(x) + b

To find b plug in the x and y values from (2,-4) into the equation to get

         -4 = -1/5(2) + b

          b = -4 + 1/5(2)

          b = -4 + 2/5

          b = -18/5

The equation of the perpendicular line is y = -1/5(x) -18/5

Macy's buys a coat from the manufacturer for $22.00. They markup the coat by 75%. Ms. Tonyes buys the coat and uses a 15% off co
Arlecino [84]

Answer:

Toney buys the coat for $ 14.8.

Step-by-step explanation:

Cost of coat =$ 22

Mark up by 75 %

discount = 10 %

Let toney pay $ R for the coat.

So, according to the question

R + 75 % R = 1.75 R

Now the cost is

1.75 R - 15 % of 1.75 R = 22

1.75 R - 0.2625 R = 22

R = 14.8

So, he buy the coat for $ 14.8.

Choose the correct answer in scientific notation.
vladimir2022 [97]

Answer:

B. 1.55 x 106

Step-by-step explanation:

This is an example of the distributive property. In order to turn it back to the regular form, you need to do this:

3.40

-

1.85

--------

1.55      

Don't forget to put the 106!

3.40

-

1.85

--------

1.55      x       106

You can do it in both forms and get the same answer. It depends on what the question asks for or whichever form you like best/you think is the easiest.
