6 years
A parent increases a child’s monthly allowance by 20% each year. If the allowance is $8 per month now. This is an exponential function, An exponential function is given by:
Let x be the number of years and y be the allowance. The initial allowance is $8, this means at x = 0, y = 8
Since it increases by 20% each year, i.e 100% + 20% = 1 + 0.2 = 1.2. This means that b = 1.2
Therefore:
To find the number of years will it take to reach $20 per month, we substitute y = 20 and find x
x = 6 years to the nearest year

Step-by-step explanation:

Answer:
2x
Step-by-step explanation:
f(x) – g(x)
f(x) = 5x – 3 and g(x) = 3x – 3
f(x)- g(x) = 5x – 3 -( 3x – 3)
Distribute the minus sign
5x -3 -3x+3
Combine like terms
5x-3x-3+3
2x
Answer:
9/22
Step-by-step explanation:
1/2 + x=10/11
Subtract 1/2 from each side
1/2-1/2 + x=10/11-1/2
x = 10/11 -1/2
Getting a common denominator of 22
x = 10/11*2/2 -1/2 *11/11
x = 20/22 - 11/22
x = 9/22
