The cost c (in dollars) od making n feet of cabinet is represented by c = 18n + 45. how many feet of cabinet are made when the cost is $441?

22 feet

Step-by-step explanation: Because of the +45 in the equation, you subtract that from the total cost. That leaves you with 396. You divide that by 18 to get n alone, which gives you 22.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

this is answer of 144 cubic meters
