Answer:
10
Step-by-step explanation:
Plug in 5 for x, and 10 for y in the expression:
5 + 7(5) - 3(10)
Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponent (& Roots)
Multiplication
Division
Addition
Subtraction
First, Multiply:
7 * 5 = 35
-3 * 10 = -30
5 + 35 - 30
Combine like terms:
(5 + 35) - 30
40 - 30 = 10
10 is your answer.

Step-by-step solution:
7x + 3 + 6x + 11 = 0
7x + 6x + 11 + 3 = 0
13x + 11 + 3 = 0
13x + 14 = 0
13x = 0 - 14
13x = -14
x = -14 / 13
x = -1.077 approx.

A) Total = Principal * (1 + rate)^years
Total = 500 * (1.015)^years
b) The equation has to be solved for years.
http://www.1728.org/compint2.htm
Years = {log(total) -log(Principal)} ÷ log(1 + rate)
Years = [log (800) - log(500)] / log (1.015)
Years = (2.903089987 -2.6989700043) / 0.0064660422492
