During a week:
Kevin works 3z during 5 days
kevin work (4z-7) during 1 day.
Kevin work 0 during 1 day.
z=unit time
f(z)= number of hours kevin works in one week.
f(z)=5(3z)+(4z-7)+0
f(z)=15z+4z-7
f(z)=19z-7
The number of hours kevin woirs in one week in terms of z is:
f(z)=19z-7
Answer:
A The solution is a point in the coordinate plane.
Step-by-step explanation:
The slope of each of these lines is the coefficient of x. The slopes are different, so the lines must intersect in one point. That point is not on either of the x- or y-axes.
The solution set is a point in the coordinate plane.
__
Since these are equations, the solution set is not a region. It would be a region if these were inequalities.
