Step-by-step explanation:
the equation of the line is given in y=mx+b form and b is where the y axis is intersected, but it is also a point on the line.

<span>The given function is f(x) = (7x + 1)/2. Write it as y = (7x)/2 + 1/2. To determine the inverse do these 3 steps. Step 1: Swap x and y to obtain x = (7y)/2 + 1/2. Step2: Solve for y. First, multiply through by 2 to obtain 2x = 7y + 1. Second, subtract 1 from each side to ontain 2x - 1 = 7y. Third, divide through by 7 to obtain (2x - 1)/7 = y. Step 3: Set y to the inverse of f(x) to obtain f^(-1) (x) = (2x - 1)/7.</span>
Answer:
x=27
Step-by-step explanation:
3=x/9
9*3=(x/9)*9
27=x
x=27
Multiply by 9 on both sides to get the x by itself because x(1/9)*9=x, and when you do something to one side of the equation you also have to do it to the other side.
