Divide the total centimeters by centimeters per inch:
51.78 / 2.54 = 30.386 inches.
F(x) = 4x - 1
All you have to do is substitute the values in the domain for x in the function.
f(-1) = 4(-1) - 1
f(-1) = -4 - 1
f(-1) = -5
f(0) = 4(0) - 1
f(0) = -1
f(1) = 4(1) - 1
f(1) = 4 - 1
f(1) = 3
And so on.
B=30. all you have to do is minus 9 from both sides then multiply 6 to each side so all thats left is the variable
