4y + 5+ 3y
The coefficients would be 4 and 3 because they have a variable after them and the constant would be 5.
1) I'm guessing your question is x * x^3
the answer for that would be x^4
2) T^21
3) the answer is not reasonable as the sum of those 2 numbers is 354.94
4) -12x
To solve this, write an equation.
300 is your starting balance, add this to your equation.
300
You get 7% more each year, but you can't multiply by 7% because that will make it decrease by 93%. You have at add 1 to 7%.
300(1.07)
Lastly, the 18 variable for the years.
300(1.07)^18
Solve the equation and get $1013.97968 or $1013.98
