You buy the same number of brushes, rollers, and paint cans. Write an expression in simplest form that represents the total amou
Soloha48 [4]

If you buy ' N ' of each item, then you'll pay  3.99N  for brushes,
21.79N  for cans of paint, and  6.89N  for rollers.

The question assures us that you bought the same number of
each item.  So your total bill at the hardware store checkout is

                      3.99N + 21.79N + 6.89N

                 =  N (3.99 + 21.79 + 6.89)

                 =        32.67 N .

How do you graph? <br> y=−4/3x+8y
trasher [3.6K]

How do we graph anything? Make a table of values for x and y and then plot each point. After plotting each point on the xy-plane, connect each point with a straight line or curve (depending on the function).


In this case, we must first isolate y.


y = (-4/3)x + 8y


y - 8y = (-4/3)x


-7y = (-4/3)x


y = (-4/3)x ÷ (-7)


y = (4/21)x


Now follow the steps above.

How do you find surface area of a triangular prism ?
RSB [31]
The formula to find the surface area of a triangular prism is basically finding out the area of one of the faces of a traingle, which is:

<span>(base)*(height)/2

</span>So, basically you take the face of the triangle that your trying to find the surface area of and plug in your values for the base length and height, multiply them together, hen divide that product by 2 to find your surface area :)


Thank you for the question! I hope this helped! Have an amazing day!! :D

The equation for the line g can be written as x-y=9. Line h is parallel to line g and passes through (4,5). What is the equation
Gnoma [55]

Answer:

y = x+1

Step-by-step explanation

The equation in slope intercept form is expressed as y = MX+c

m a the slope

Get the slope of the line

Given the line x-y =9

-y = -x+9

y = x-9

Slope of the line is 1

Since it is parallel to the given line, the slope o the required line is also 1

Substitute m = 1 adnd (4,5) into the point slope form

y-y0 =m(x-x0)

y - 5 = 1(x-4)

y-5 = x-4

y= x-4+5

y = x+1

Hence the required equation is y = x+1
