Madeline Rollins is trying to decide whether she can afford a loan she needs in order to go to chiropractic school. Right now, Madeline is living at home and works in a shoe store, earning a gross income of $1,260 per month. Her employer deducts a total of $320 for taxes from her monthly pay. Madeline also pays $190 on several credit card debts each month. The loan she needs for chiropractic school will cost an additional $290 per month.

Calculate her debt payments-to-income ratio with and without the college loan. (Remember the 20 percent rule.) (Enter your answers as a percent rounded to 2 decimal places.)

With college loan: __%

Without college loan: __%

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

8

step-by-step explanation:

i think the answer is b x = 1, y = 35/2
