Jeff, an electrician, had a job that lasted 5.5 hours, during which time he earned $32 per hour and charged a $25 service fee. The function J(t) represents the amount Jeff earns in t hours

Step-by-step explanation:

This is a linear relationship:

Rate per hour is the slope, service fee is the y-intercept:

The equation is:

The amount of charge per 5.5 hour job:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

a - base

b - exponent

so,
