8. When you’re making subsets, you have two options for each element in the original set: you can either include it or not. This gives you 2 x 2 x 2 = 8 possible ways you can put a subset together from the three elements in {3, 4, 5}.
That represents exponential growth because we are multiplying by 2.1 every time. Since you are multiplying by a number greater than 1 that means that the number is getting bigger as x gets bigger. This means that we have exponential growth.
70 because mulitplying 7 by 10 gives you 70 and 1/10 of 70 is 7
Solve for m:
8 = m/4
8 = m/4 is equivalent to m/4 = 8:
m/4 = 8
Multiply both sides of m/4 = 8 by 4:
(4 m)/4 = 4×8
(4 m)/4 = 4/4×m = m:
m = 4×8
4×8 = 32:
Answer: m = 32 thus m - 12 = 32 -12 = 20
4 and 3 fifths i think 4 3/5
