Combining like terms, move the one with coefficient a to the left, and move the constant to the right
\dfrac{a}{2} -  \dfrac{2}{3} =a+ \dfrac{1}{5}
\dfrac{a}{2} - a =\dfrac{1}{5} + \dfrac{2}{3}

equalize the denominators in like-terms
\dfrac{a}{2} - \dfrac{2a}{2} =\dfrac{1 \times 3}{5 \times 3} + \dfrac{2 \times 5}{3 \times 5}
\dfrac{a}{2} - \dfrac{2a}{2} =\dfrac{3}{15} + \dfrac{10}{15}

do the operation to the numerators
\dfrac{-a}{2} =\dfrac{13}{15}

solve for a
-a = \dfrac{13}{15} \times 2
-a = \dfrac{26}{15}
a = - \dfrac{26}{15}

There is a rule:

One input(x-value) can only have one output(y-value) in order to be a function.

If one input has more than one output, it is not a function.

(This doesn't apply to outputs, one output can have more than one input and still be a function)

The 1st option is not a function because the inputs 9 and 10 have more than one output.

The 2nd option is not a function because the input 3 has more than one output.

The 3rd option is a function because each input only has one output.

The 4th option is not a function because the input 5 has more than one output.

frutty [35]

Answer:

the answer is the first one

Step-by-step explanation:

39.99 rounded up is 40.00

40.00*0.05 = 2, 40-2 = 38

20.00*0.15 = 3, 20-3 = 17*.05 = 0.85, 17-0.85 = 16.15

38+16.15 = 54.15
