can you guy help me to do that

Answer: To convert a percentage to decimal form, you need to divide the number in the percent by 100. In reality, that just looks like moving the decimal point to the left two places.

83% / 100 = 0.83

83% in decimal form is 0.83.

Hope that helped! =)

83% / 100 = 0.83

83% in decimal form is 0.83.

Hope that helped! =)

Write an equation in slope-intercept form for a line that is (a) parallel (b) perpendicular to the line y=-5x-3 and has a y-intercept if 6

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

The given equation is y = -5x-3

Compared to y = mx + c, the slope, m is - 5

a) if two lines are parallel, it means that they have equal slope. Therefore the slope of the line parallel to y = -5x-3 is - 5. Since the y intercept is 6, the equation would be y = - 5x + 6

b) if two lines are perpendicular, the slope of one line is the negative reciprocal of the line perpendicular to it. Since the slope of the given line is - 5, the slope of the line perpendicular to it is 1/5. The equation becomes

y = x/5 + 6

Michael, a freelance editor, charges the rates shown in the table below to edit manuscripts. The cost per page increases as the quality of editing improves. Michael also gives a 5% discount if the entire amount is paid up front. A 2 column table with Type of Editing and Cost per page as the column headings. Express Proofreading costs 2.20 dollars, Basic Proofreading 2.80 dollars, Extended Proofreading 3.90 dollars, and Deep Editing 12 dollars Maria has a 25-page manuscript. The equation below shows the relationship between the total cost of editing 25 pages, T, and the cost per page, c, if she gets the 5% discount: 25c − 0.05(25c) = T Using the equation, what is the best quality of editing that Maria can get done for a maximum of $66.50?

Using the equation, the cost per page Maria can afford is

25c -.05(25c) = 66.50

0.95*25*c = 66.50

c = 66.50/(0.95*25) = 2.80

The best quality of editing that Maria can afford is ...

Basic Proofreading

25c -.05(25c) = 66.50

0.95*25*c = 66.50

c = 66.50/(0.95*25) = 2.80
