Y= {2,4,6,8,10,12,14,16,18,20}<br>
X={4,8,12,16,20,24,28,32,36,40}<br>
Find the difference Y-X
olganol [36]
Answer:
difference between Y-X = 2
Step-by-step explanation:
you can subtract 2-4 in Y and also in X 4-8
as the difference between 2 (2-4, 4-8) number would be 2. therefore difference is 2
Hope it have benefited u.
X = number of dimes
x + 2 = number of nickels
3(x + 2) = number of pennies
10x + 5(x + 2) + 3(x + 2) = 52
10x + 5x + 10 + 3x + 6 = 52
18x = 36
x = 2
x = 2 (number of dimes)
x + 2 = 4 (number of nickels)
3(x + 2) = 12 (number of pennies)
Check:
2(10) = 20 cents in dimes
4(5) = 20 cents in nickels
12(1) = 12 cents in pennies
Total = 52 cents
Answer:
5^x - 5^-x
Step-by-step explanation:
g(x) = 5^-x
h(x) = 5^x
We want h(x) - g(x)
h(x) - g(x) = 5^x - 5^-x
This cannot be simplified
