Liam wants to buy a car and pay for it in three installments. the total cost of the car is $29,000. two times the first installment is $1,000 more than the sum of the third installment and three times the second installment. liam must pay 15% interest on the second and the third installments: the interest will amount to $2,100. if x, y, and z represent the first, second, and third installments, respectively, identify the augmented matrices that model liam's situation.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
