Answer:
f(12) = 1680
Step-by-step explanation:
Substitute n = 12 into f(n) , that is
f(12) = 250 + 130(12 - 1) = 250 + 130(11) = 250 + 1430 = 1680
5/-3
Slope = (y2 - y1)/(x2 - x1)
m = (8 - 3)/(-7 + 4)
m = 5/-3
x=3
5x+6=21
5x=15
3
Step-by-step explanation: You divide 45 and 60 then you mutiple the number by 4 then find your answer after you done solved this is how you solve it 45 divided by 60=0.75 mutiply by 4=3
