Lee has a credit card with a 22.3% apr and a 30-day billing period that uses the average daily balance method to calculate the finance charge. his daily balances for one billing period are shown in the following chart. lee had a previous balance of $445.93, made a payment of $350, and has new purchases that total $1,643.57. determine lee’s average daily balance.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
