Step-by-step explanation:
Given that Tim has developed a money saving strategy that uses the formula S=450+100r.
a) 450 will be savings always and for every r an additional 100 would be saved
b) Slope = 100 represents the increase of S for a unit increase of 1.
S intercept = 450 is the savings even when r=0
c) Since max savings is 1250 and min is 450
Range = (450,1250)
For 450 range, domain r =0 and for range 1250, domain r = 8
Domain =(0,8)
B) The Slope represents the time it takes to make 100 dollars, and S represents the total amount of money Tim has.
C) If Tim got to 1250 dollars, it would be 8 for R. So 8 would be the domain and 1250 for the range.

Answer:
1 5/36
Step-by-step explanation:
need a common denominator which would be 36
to get from 9 to 36 you multiply by 4 so 5 would be multiplied by 4 to get the fraction 20/36
do the same with 7/12 12x3 is 36 and 7x3 is 21 so 21/36
then add 20+21=41
put over 36 41/36
Find if you can lower it which you can:
41 is bigger than 36 by 5 so your ending fraction would be 1 and 5/36 because 5 and 36 don't have a common factor.
