Solve the equation for a. K = 4a + 9abThe goals against average (A) for a professional hockey goalie is determined using the formula A = 60 a equals 60 left-parenthesis StartFraction g Over t EndFraction right-parenthesis.. In the formula, g represents the number of goals scored against the goalie and t represents the time played, in minutes.

a = k/(4+ 9b)

Step-by-step explanation:

Given the equation above, we want to make a the subject of the formula

k = 4a + 9ab

Factor a out from the right hand side

k = a ( 4 + 9b)

Divide both sides by (4 + 9b)

a = k/(4 + 9b)

step-by-step explanation:

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
