Just combine like terms: all of the x^2 together, all of the x's together and all of the numbers:
3x2+5x2+5x-2-1
8x2+5x-3 simplified, so letter A
Answer:
17,500,000 people
Step-by-step explanation:
70% can be rewritten as 0.7 time 25 million
0.7*25,000,000 = 17,500,000
The given condition is an arithmetic sequence with the first term (a1) is 1 penny and the common difference (d) is 1 penny. A year that is not a leap year has 365 days (n). The arithmetic series (S) is calculated through formula,
S = (n/2) (2a1 + (n - 1) x d)
Substituting the known values,
S = (365/2) (2 x 1 + (365 - 1) x 1)
S = 66795 pennies
A dollar is 100 pennies. Therefore, at the end of the year, the total savings is $667.95.
Answer:
b, k = -4
Step-by-step explanation:
3/2 = k + 11/2
=> 3/2 - 11/2 = k
=> -8/2 = k
=> k = -4
