In the form of the exponential function:f ( x ) = a · b^x,the base of the function is b.In this case: a = 7,000 ( starting value ) and b = 1 - 0.1 = 0.9f ( x ) = 7,000 · ( 0.9 )^xwhere x represents the number of the years : x = 0, 1, 2, ...Answer: The base is 0.9.
3/2 and 9/10. Look at the denominators. 2 times what number equals 10. That number would be 5. So if you multiply the first fractions denominator by 5 you get 10. Do the same to the top. you get a new fracrion which is 15/10. Add normally. 15/10 + 9/10 = 24/10. In lowest terms it is 2 2/5 (2 wholes and 2 out of 5)
Eliminate parentheses using the distributive property.

5260x = 4562
x = 4562/5260
x = 2281/2630
6 1/4! explanation: 2 3/4 + 3 = 5 3/4 next, 5 3/4 + 2/4 = 6 1/4
