Given:
The equation is
![\dfrac{1}{3}x=\dfrac{1}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B3%7Dx%3D%5Cdfrac%7B1%7D%7B5%7D)
To find:
The coefficient and reciprocal.
Solution:
We have,
![\dfrac{1}{3}x=\dfrac{1}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B3%7Dx%3D%5Cdfrac%7B1%7D%7B5%7D)
Here,
is multiplied with x.
So, the coefficient of x is
.
To find the reciprocal, we need to interchange numerator and denominator of a fraction.
So, the reciprocal of
is ![\dfrac{3}{1}=3](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B1%7D%3D3)
Therefore, the reciprocal is 3.
Her check register will have a surplus of 64 dollars compared to her actual balance.
example
100 +32 = 132 (incorrect)
100 -32 = 68 (correct)
132 -68 = 64 surplus
Hello from MrBillDoesMath!
Answer:
f(x) = 8 * 3^x
Discussion:
x = 0: f(x) = 8
x = 1: f(1) = f(0) * 3 = 8*3
x = 2: f(2) = f(2-1)*3 = f(1) * 3 = (8*3)*3 = 8 * 3^2
x=3 : f(3) = f(3-1)*3 = f(2)*3 = (8 * 3^2) * 3 = 8 * 3^3
Based on this we guess that
f(x) = 8 * 3^x
Thank you,
MrB
