Answer:
4/12
Step-by-step explanation:
rate of change formula
f(b) - f(a) / b-a
f (5)- f (1) / 12-0
5-1 / 12-0
3x + 1 = x + 5
2x + 1 = 5
2x = 4
x = 2
y = 3(2) + 1 = 6 + 1 = 7
y = 7
(2,7)
this is the equation of a line in slope intercept form with a slope of 1/4 and a y intercept of -5
410/1080=(0.915)^x
0.379=(0.915)^x
ln0. 379/ln0.915=x
X=10.903
