Answer:

1/5

Step-by-step explanation:

2/5 - 1/7 = ???

find the least common denominator!

45 would be the least common demoninator!

so...

2 (7) / 5(7) - 1 (5) / 7 (5) = ?

14/ 45 - 5 /45 = ?

14 - 5 = 9

9/45. Simplify!

9/45 divide 9 from both sides

9/9 / 45/9

= 1/5, one fifths is your answer!

What is the rule for the pattern 3 12 6 24 12 48 24

schepotkina [342]

Multiply by 4 is your rule

3 x 4 = 12

6 x 4 = 24

12 x 4 = 48

To solve for the answer for 24, multiply it by 4

24 x 4 = 96

96 is the match for 24

hope this helps

In 2003 there were 1078 JC Penney stores and in 2007 there were 1067 stores.

Tamiku [17]

Answer:

a) $f(s)=\frac{-11}{3}s+\frac{3245}{3}$ $f(1)=1078 stores$ b) 2012, 1049 stores. 2014, 1041 stores. c) Yes it is a downsizing company.

Step-by-step explanation:

s=year | f(s) = number of stores per year

1 | 1078

4| 1067

$m=\frac{1067-1078}{4-1}\Rightarrow m=\frac{-11}{3}\\1078=-\frac{11}{3}*1+b\Rightarrow b=\frac{3245}{3}\\f(s)=\frac{-11}{3}s+\frac{3245}{3}$

s=1 in 2003

$s=1 year =2003\\ Testing\\f(1)=\frac{-11}{3}(1)+\frac{3245}{3}=\frac{3234}{3}=1078\\ f(1)=1078$

b) For 2012, s=9. For 2014, s=11

$\\f(s)=\frac{-11}{3}s+\frac{3245}{3}\\ \\f(9)=\frac{-11}{3}(9)+\frac{3245}{3}\cong1049\\\\f(11)=\frac{-11}{3}(11)+\frac{3245}{3}\cong=1041$

c) In deed. Since the function shows a decreasing amount of JC Penney stores. Maybe this is a downsizing from this company, progressively closing some stores.
