21x -15 + 5 = 10x - 5
21x -5 = 10x
11x = 5
x = 5/11
The cash price of the car includes the amount of the loan plus the amount of the down payment
Cash price=the loan of the car+down payment
First find the amount of the loan by using the formula of the present value of an annuity ordinary which is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv the amount of the loan ?
PMT payment per month 355
R interest rate 0.071
K compounded monthly 12
N time 5years
Pv=355×((1−(1+0.071÷12)^(−12
×5))÷(0.071÷12))
=17,885.56
Cash price=17,885.56+2,500
=20,385.56....answer
The independent variable would be the fixed rate of $3 because the amount for each mile driven changes based on how far they drive
4 = 7 - 3
1 = 4 - 3
-2 = 1 - 3
-5 = -2 - 3
=> An = A (n-1) - 3, where A1 = 7
The next term is A6 = A5 - 3 = - 5 - 3 = - 8
So the answer is the fourth option.
Slope = change in y / change in x
= (8 - -3) / (1 - 2) = (8 + 3) / ( 1 - 2)
= 11 / -1
= -11
Slope is negative.
