Answer:
f(x) = -2x+6
Step-by-step explanation:
Given the equation 10x+5y=30, in order to write as a function form, we need to make y the subject of the formula from the given function as shown;
10x+5y=30
Subtract 10x from both sides
10x+5y - 10x= - 10x+30
5y = -10x + 30
Divide through by 5
5y/5 = -10x/5 + 30/5
y = -2x + 6
Hence the required equation in function form is f(x) = -2x+6
