Domain of fg(x) is determined by the domain of g(x).g(x) has domain such that x is any real number.So domain fg(x) is x such that x is any real number.
15 students/45 tacos=? students/450 tacos
15 x 450=6750
6750/45=150
Gary would be making 450 tacos for 150 students
Equation of a line: y = mx + b
m = slope(rise/run), b = y-intercept
1/2
y = 1/2x - 3
-7/4
y = -7/4x +4
-1/2
y = -1/2x - 3
-1/4
y = -1/4x + 2
1
y = x
-1
y = -x
