Me on this one math if you dont know it dont answer!

f(x) = 18/(6+5*e^(-0.1*x))

f(6) = 18/(6+5*e^(-0.1*6)) replace every x with 6

f(6) = 18/(6+5*e^(-0.6))

f(6) = 18/(6+5*0.54881163609391)

f(6) = 18/(6+2.74405818046956)

f(6) = 18/8.74405818046956

f(6) = 2.05854074029428

f(6) = 2.1 round to the nearest tenth (one decimal place)

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
