In this case the two equations<span> describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) will satisfy the </span>equation<span> of either line. Thus the pair (x, y) is the one and only </span>solution to the system of equations<span>.</span>
Answer:
1.) [B]
2.) [C]
(3.) [D]
Step-by-step explanation:
1.) Initial amount = $3168
Annual percentage rate = 12.75
per month percentage rate = 1.06%
Interest after 3 months = P*R*T/100
= 3168*1.06*3/100
= 100.74 (aprox)
Balance after 3 months = 3168-100.74
= $3270.06 (aprox) (B.)
2.) Gross pay = $2759
Total interest rate = 7.65%+12%+7% = 26.65%
interest amount= 26.65% *2759 =$728.24 (aprox)
Housing and fixing expenses= $728.54 (C.)
3.) 1 hour = $8.25
1 week= 35 hours
3 weeks = 35*3 hours = 105 hours
Total income= 105 hours = $8.25*105= $866.25
Total interest to be deducted = 7.65+13+9 = 29.65 %
Income after deducting interest = $866.25-256.843 = $609.407
(D.)
Answer:
Step-by-step explanation:
Evaluate g(- 4) and f(- 4) by substituting x = - 4 into g(x) and f(x), that is
f(- 4) = - 10(- 4) + 9 = 40 + 9 = 49
g(- 4) = (- 4)² + 12 = 16 + 12 = 28
Then
= =
