<span>If x represents the year then that implies that y is equal to the number of new diseases every year.
Therefore in order to solve this equation you need to input x.
y= -2(15)^2 + 36(15) +6
Now solve, but please remember to use PEDMAS order in order to solve this problem.
P= Parentheses
E= Exponents
D = Division
M= Multiplication
A= Addition
S= Subtraction
So solve the parentheses first
y= -30^2 + 540 + 6
Now the exponent.
y= 900 + 540 + 6
Now add them all together.
y= 1446
So 1,446 is the number of new cases in year 15.
